The Tropical Cyclone Public Advisory is the primary tropical cyclone information product intended for a general audience.
It provides critical tropical cyclone watch, warning, and forecast information for the protection of life and property.
The Public Advisory has five sections:
1) A summary table of several cyclone parameters is placed at the top of the product in a fixed format that is suitable
for parsing by computer software. This section contains the cyclone position in latitude and longitude coordinates, its
distance from a well-known reference point, the maximum sustained winds, the cyclone’s current direction and speed of motion,
and the estimated or measured minimum central pressure.
2) A summary of all current coastal watches and warnings for the cyclone with recent changes to the watches and warnings highlighted at the top.
3) A discussion of the cyclone’s current characteristics, including location, motion, intensity, and pressure and a general description of the
predicted track and intensity of the cyclone over the next 72 hours. When conditions warrant, a discussion of the cyclone’s forecast track and
intensity through 5 days will be included. Any pertinent weather observations will also be included in this section.
4) A section that includes information on hazards to land, generally within the time period when watches and/or warnings are in effect. This
section includes information on hazards such as storm surge, wind, rainfall, tornadoes, and rip currents associated with the cyclone. When
numerous locations are affected by storm surge or rainfall, weblinks will be provided to direct users to pertinent graphical hazard information.
5) A section that states the time of the next advisory issuance.
Public advisories are issued for all Atlantic, eastern, and central Pacific tropical or subtropical
cyclones. Public advisories on potential tropical cyclones may be issued for disturbances that are
not yet a tropical cyclone, but which pose the threat of bringing tropical storm or hurricane conditions
to land areas within 72 hours. Post-tropical cyclone public advisories are issued when a cyclone continues
to pose a significant threat to life and property after it is no longer tropical, and if the transfer of
responsibility to another office would result in an unacceptable discontinuity of service.
Public advisories for Atlantic tropical cyclones are normally issued every six
hours at 5:00 AM EDT, 11:00 AM EDT, 5:00 PM EDT, and 11:00 PM EDT (or 4:00 AM EST, 10:00 AM EST, 4:00 PM EST, and 10:00 PM EST).
Depending on the cyclone’s location and forecast track, advisories may also be issued in Central Time (CDT or CST), Atlantic Standard
Time (AST), Cabo Verde Standard Time (CVT), or Greenwich Mean Time (GMT).
Public advisories for Eastern Pacific tropical cyclones are normally issued every six
hours at 2:00 AM PDT, 8:00 AM PDT, 2:00 PM PDT, and 8:00 PM PDT (or 1:00 AM PST, 7:00 AM PST, 1:00 PM PST, and 7:00 PM PST).
Depending on the cyclone’s location and forecast track, advisories may also be issued in Central Standard Time (CST), Mountain
Standard Time (MST), or Hawaiian Standard Time (HST).
Public advisories for Central Pacific tropical cyclones are normally issued every six
hours at 5:00 AM HST, 11:00 AM HST, 5:00 PM HST, and 11:00 PM HST.
Intermediate public advisories are issued every 3 hours when coastal watches or warnings are in effect.
United States tropical cyclone watches or warnings can be issued with regular or intermediate public advisories.
Additionally, special public advisories may be issued at any time due to
significant changes in warnings or in the cyclone.
The numbers 1-5 in the headers are assigned on a rotating basis by
cyclone number, i.e., advisories on the first, sixth, or eleventh
cyclones of the Atlantic season would be sent under the
WMO
header WTNT31 KNHC; advisories on the
second, seventh, or twelfth cyclones of the Atlantic season would be sent
under the
WMO
header WTNT32 KNHC, and
so on.

The Tropical Cyclone Forecast/Advisory contains current and forecast storm information in a fixed format suitable
for parsing by computer software. It contains the cyclone position, intensity, and direction and speed of motion.
It also includes the current maximum radial extent of 4-meter seas, as well as the maximum radial extent of winds of
34, 50, and 64 kt in each of four quadrants around the storm. The Forecast/Advisory contains quantitative forecast
information on the track, intensity, and size of the cyclone valid 12, 24, 36, 48, 60, 72, 96, and 120 h from the
forecast’s nominal initial time. Tropical storm and 50-kt wind radii are forecast out to 120 h and hurricane-force
wind radii are forecast out 72 h.
The Forecast/Advisory also contains the predicted status of the cyclone for each forecast time. This status may include
any of the following: inland, dissipated, post tropical, or change in status from subtropical to tropical (or vice versa).
“Post tropical” describes a cyclone that no longer possesses sufficient tropical characteristics to be considered a tropical
cyclone; however these cyclones can continue to produce heavy rains and high winds. A remnant low is a post-tropical cyclone
that no longer possesses the convective organization required of a tropical cyclone and has maximum sustained winds of less
than 34 knots. An extratropical cyclone is a cyclone of any intensity for which the primary energy source results from the
temperature contrast between warm and cold air masses.
Forecast/Advisories are issued on all Atlantic,
eastern Pacific
, and
central Pacific
tropical and subtropical
cyclones every six hours at 0300, 0900, 1500, and 2100 UTC
(learn about UTC time)
Forecast/Advisories on potential tropical cyclones
may be issued for disturbances that are not yet a tropical cyclone, but which pose the threat of bringing tropical
storm or hurricane conditions to land areas within 72 hours. Post-tropical cyclone Forecast/Advisories are issued
when a cyclone continues to pose a significant threat to life and property after it is no longer tropical, and if
the transfer of responsibility to another office would result in an unacceptable discontinuity of service.
Special Forecast/Advisories may be issued at any time due to significant changes in warnings or in the cyclone.
The numbers 1-5 in the headers are assigned by cyclone number, i.e.,
advisories on the first, sixth, or eleventh cyclones of the Atlantic
season would be sent under the
WMO
header WTNT21 KNHC; advisories on the second, seventh, or twelfth

The Tropical Cyclone Discussion describes the rationale for the forecaster’s analysis and forecast of a tropical cyclone.
It will typically discuss the observations justifying the analyzed intensity of the cyclone, a description of the environmental
factors expected to influence the cyclone’s future track and intensity, and a description of the numerical guidance models. It
may also describe the forecaster’s degree of confidence in the official forecast, discuss possible alternate scenarios,
highlight unusual hazards, and provide a summary of key messages. The product also includes a table of forecast positions and
intensities in knots and miles per hour out to 120 h. This table also indicates the forecast status of the cyclone, which may
include any of the following: inland, dissipated, post tropical, or change in status from subtropical to tropical (or vice versa).
“Post tropical” describes a cyclone that no longer possesses sufficient tropical characteristics to be considered a tropical
cyclone; however these cyclones can continue to produce heavy rains and high winds. A remnant low is a post-tropical cyclone
that no longer possesses the convective organization required of a tropical cyclone and has maximum sustained winds of less than
34 knots. An extratropical cyclone is a cyclone of any intensity for which the primary energy source results from the temperature
contrast between warm and cold air masses.
Tropical Cyclone Discussions are issued on all Atlantic,
eastern Pacific
, and
central Pacific
tropical and subtropical
cyclones every six hours. Tropical Cyclone Discussions on potential tropical cyclones may be issued for disturbances that are not
yet a tropical cyclone, but which pose the threat of bringing tropical storm or hurricane conditions to land areas within 72 hours.
Post-tropical cyclone Discussions are issued when a cyclone continues to pose a significant threat to life and property after it is
no longer tropical, and if the transfer of responsibility to another office would result in an unacceptable discontinuity of service.
Special tropical cyclone discussions may be issued at any time due to significant changes in warnings or in the cyclone.
Tropical Cyclone Discussions for Atlantic tropical cyclones are normally issued every six
hours at 5:00 AM EDT, 11:00 AM EDT, 5:00 PM EDT, and 11:00 PM EDT (or 4:00 AM EST, 10:00 AM EST, 4:00 PM EST, and 10:00 PM EST).
Depending on the cyclone’s location and forecast track, advisories may also be issued in Central Time (CDT or CST), Atlantic Standard
Time (AST), Cabo Verde Standard Time (CVT), or Greenwich Mean Time (GMT).
Tropical Cyclone Discussions for Eastern Pacific tropical cyclones are normally issued every six
hours at 2:00 AM PDT, 8:00 AM PDT, 2:00 PM PDT, and 8:00 PM PDT (or 1:00 AM PST, 7:00 AM PST, 1:00 PM PST, and 7:00 PM PST).
Depending on the cyclone’s location and forecast track, advisories may also be issued in Central Time (CDT or CST), Mountain Time
(MDT or MST), or Hawaiian Standard Time (HST).
Tropical Cyclone Discussions for Central Pacific tropical cyclones are normally issued every six
hours at 5:00 AM HST, 11:00 AM HST, 5:00 PM HST, and 11:00 PM HST.
For select tropical cyclones, the Tropical Cyclone Discussion will have a companion

FOPZ11-15 KNHC (MIAPWSEP1-5) – Eastern Pacific
FOPA11-15 PHFO (HNLPWSCP1-5) – Central Pacific (issued by
CPHC
The
Tropical Cyclone
Surface Wind Speed Probabilities text product provides probabilities, in percent,
of sustained wind speeds equal
to or exceeding 34-, 50-, and 64-knot wind speed thresholds. These wind speed
probabilities are based on the track, intensity, and wind structure forecasts and uncertainties
from the
National Hurricane Center
and the
Central Pacific Hurricane Center
and are computed
for coastal and inland cities as well as offshore locations (e.g., buoys).
These text products are issued on all Atlantic and
eastern Pacific
tropical and subtropical
cyclones, and potential and post-tropical cyclones when appropriate, every six hours at 0300, 0900, 1500, and 2100 UTC
(learn about UTC time)
Special tropical cyclone surface wind speed probabilities may be issued at any time due to significant changes in warnings or in the cyclone.
The numbers 1-5 in the header are assigned on a rotating basis by cyclone number, i.e.,
probabilities on the first, sixth, or eleventh cyclones of the Atlantic season would be sent
under the WMO header FONT11 KNHC; probabilities on the second, seventh, or twelfth cyclones of
the Atlantic season would be sent under the WMO header FONT12 KNHC, and so on.
Three types of tropical cyclone wind speed probability values are created
. Not all of these values will be distributed or placed on the Internet.
For each probability value, the event in question is a sustained (one-minute average)
surface (10 m) wind speed of at least a particular threshold value (34, 50, or 64 kt)
at a specific location.
Cumulative
– These values tell you the overall probability the event will
occur sometime during the specified cumulative forecast period (0-6 hours, 0-12,
0-18, etc.) at each specific point. These values are provided in both the text
and
graphical formats.
In the
text product
, the numbers are in parentheses.
The
graphical products
depict
only cumulative values. The text product is transmitted
to users via normal NWS dissemination methods. The graphic is available on the internet from the
National Hurricane Center
and the
Central Pacific Hurricane Center
Individual
– These values tell you the probability the event will
start
sometime during the specified individual forecast period (0-12 hours, 0-24 hours, 0-36 hours, etc.)
at each specific point. These periods are individual, since nothing that
occurs before or after the specified period affects the probability. These values
are provided only in the text NHC product. They are the values outside of the
parentheses (cumulative values are in the parentheses). The term "individual" also
makes a clear distinction from the cumulative period values for users.
Incremental
– These values tell you the probability the event will
occur
sometime during the specified forecast period (0 - 6 hours, 6-12, 12-18, etc.) at each specific
point. These values are incremental since they can increase in value by accounting for the
possibility the event might start in an earlier period and still be occurring in the specified
period. Incremental probabilities are not available in the Tropical Cyclone Surface Wind Speed
Probabilities text product, but they are available in the National Digital Forecast Database (NDFD).

WTPZ71-75 KNHC (MIATUSEP1-5) – E. Pacific Spanish
WTPA61-65 PHFO (HFOTCUCP1-5) – C. Pacific
The TCU is a brief alphanumeric text product containing either block paragraph
text, a formatted storm summary section, or both. TCUs are issued to inform
users of significant changes in a
tropical cyclone
in between regularly scheduled public advisories. Such uses include, but are not limited to the following:
To provide timely information of an unusual nature, such as the time and
location of landfall, or to announce an expected change in intensity that
results in an upgrade or downgrade of status (e.g., from a
tropical storm
to a
hurricane
).
To provide a continuous flow of information regarding the center location
of a tropical cyclone when watches or warnings are in effect and the center
can be easily tracked with land-based radar.
To provide advance notice that significant changes to storm information
will be conveyed shortly, either through a subsequent TCU or through a Special
Advisory.
To announce changes to international watches or warnings made by other
countries.
To announce the forthcoming issuance or cancellation of a U.S. watch or
warning, but only if the TCU precedes a regular or special advisory that will contain the
same watch/warning information, and indicates the advisory will be issued shortly.
The storm summary section is identical in format to the storm summary section
found in the
TCP
. The storm summary section is required
whenever the TCU is issued to update storm intensity, location, or motion
information. The storm summary section is not required for TCUs issued to provide
advance notice that significant changes to storm information will be conveyed
shortly, or for those issued to convey changes to watches or warnings.

ABPA20 PHFO (HFOTWOCP) – C. Pacific
The Tropical Weather Outlook discusses significant areas of disturbed weather and their potential for development during the next
7 days, including a categorical forecast of the probability of tropical cyclone formation during the first 48 hours, and during
the entire 7-day forecast period. The 48 h and 7-day probabilities of formation for each disturbance are given to the nearest 10%
and expressed in terms of one of the following categories: low probability of development (0-30%), medium probability (40-60%), and
high probability of development (70-100%).
The Tropical Weather Outlook is issued every six hours from 15 May–30 November for the Atlantic and Eastern North Pacific basins, and
from 1 June–30 November for the Central North Pacific Basins at 0000, 0600, 1200, 1800 UTC. Local issuance times are shown in the table below.

A Special Tropical Weather Outlook is issued when there have been important changes with areas of disturbed weather over tropical
or subtropical waters that need to be conveyed before the next scheduled release of the Tropical Weather Outlook. The Special
Tropical Weather Outlook can be used to report the findings of reconnaissance aircraft missions, and can also be used for disturbances
outside of the normal hurricane season when Tropical Weather Outlooks are not routinely issued. The disturbance being updated in the
Special Tropical Weather Outlook will be highlighted at the top of the product, and other systems discussed in previous Tropical
Weather outlooks will also be included.
Please note the (Special) Tropical Weather Outlook has a companion

National Tropical Cyclone Valid Time Event Code (TCV)
World Meteorological Organization (WMO)
and AWIPS (in parenthesis) headers:
WTNT81-85 KNHC (MIATCVAT1-5) – Atlantic
WTPZ81-85 KNHC (MIATCVEP1-5) – E. Pacific
Valid Time Event Code (VTEC) is a standardized code string used to describe the parameters of weather watches, warnings,
and advisories (WWA). It is designed to help automate the delivery of NWS WWA information to customers and partners,
enabling them to relay it more quickly to the public. The National Tropical Cyclone Watch/Warning text product (TCV)
summarizes all new, continued, extended, and canceled tropical cyclone wind and storm surge
watches and warnings
issued by the National Weather Service
for the contiguous U.S., Puerto Rico, and the U.S. Virgin Islands. Separate text products are issued for
Atlantic basin storms and Eastern North Pacific storms.
The representation of watches/warnings in the National TCV is provided only in terms of NWS zones; as a result the TCV can
only convey an approximate description of the watch/warning areas. The precise lateral extent of tropical cyclone wind
watches and warnings along the coastline is specified by breakpoints in the
Tropical Cyclone Public Advisory
The precise extent of storm surge watches/warnings is specified in gridded form through the
National Digital Forecast Database (NDFD)
. The National TCV
will contain a disclaimer indicating where the precise extent of tropical cyclone watches and warnings can be found.
The National TCV will be issued with all routine, intermediate, and special advisories if US watches or warnings are continued, posted, changed, or canceled.
When active, the most current Tropical Cyclone Valid Time Event Code (VTEC) product can be
found on the
NHC home page
TCV products are also issued by each NWS Weather Forecast Office (WFO) that has tropical storm, hurricane, or storm surge
watches or warnings in effect. WFO TCVs include plain language information about the threats and impacts expected in each
affected NWS zone in addition to the VTEC as seen in this
WFO TCV example
The WFO TCV products can be found through links in the NHC storm table when an active tropical cyclone threatens U.S. land.
The WFO TCV for Hawaii (TCVHFO) provides all VTEC for active tropical storm, hurricane, and storm surge watches and warnings for Hawaii,
so there is not a separate National TCV product for the Central Pacific basin.
An overview of the VTEC program is available at

FKPZ21-25 KNHC (MIATCAPZ1-5) – E. Pacific
FKPA21-25 PHFO (HFOTCAPA1-5) – C. Pacific
The Aviation Tropical Cyclone Advisory is issued to provide short term tropical cyclone forecast guidance for
international aviation safety and routing purposes. The TCA lists the current TC position, motion, and
intensity, and includes 3, 6, 9, 15, 21, and 27 hour forecast positions and intensities after the advisory issuance time.
Position and intensity forecast information for forecast hours (+06, +12, +18 and +24) is derived from interpolated
forecast information – intensity is rounded to the nearest 5 knots.
Issuance of the Aviation Tropical Cyclone Advisory occurs every six hours at the regular advisory issuance time of 0300,
0900, 1500, and 2100 UTC
(learn about UTC time)
. TCAs for
special advisories will be issued for the same circumstances that apply for a standard advisory.
See Example
Hurricane Local Statement (HLS)
These statements are NOT produced at the National Hurricane Center, but can be found through links in the NHC
storm table
when an active tropical cyclone threatens U.S. land.
Local National Weather Service Weather Forecast Offices (WFOs) produce these local statements to keep the media, local
decision makers, and the public current on present and anticipated storm effects
in their area. The hurricane local statement provides an overview of storm information and potential
impacts on the local area.
Hurricane Local Statements generally present the following:
A headline
A description of the counties, parishes, or cities covered by the statement
Watches and/or warnings in effect and the counties or parishes to which they apply
A short overview of the most important tropical cyclone information/impacts to the local area
Recommended precautionary/preparedness actions
Present tropical storm or hurricane position, movement, and intensity
Information regarding the potential for impacts from storm surge, tropical wind, tornado, and flooding rain
The time of the next statement
When there are active tropical storm, hurricane, or storm surge watches/warnings in effect, a graphical representation of
the potential threats posed by wind, storm surge, flooding rain, and tornadoes can be found on the
Hurricane Threats and Impacts webpage
and selecting the Threats and Impacts tab.
See the
Hurricane Threats and Impacts Graphics FAQ for more information
Tropical Cyclone Reports (TCR)
These reports are available on the
NHC TCR webpage
The National Hurricane Center’s Tropical Cyclone Reports (TCRs) contain information on all tropical
(and subtropical) cyclones that have occurred within the Atlantic and eastern Pacific basins, including
synoptic history, meteorological statistics, casualties and damages, and the post-analysis best track
(six-hourly positions and intensities). Comprehensive versions of these reports are provided for all
tropical cyclones in which coastal watches or warnings were in effect or direct fatalities were reported,
and for other select storms with significant public or research interest (e.g., storms investigated via
research field campaigns). Otherwise, abbreviated TCRs will be produced that include a short description
of the cyclone’s origin, justification of the analyzed maximum winds and minimum pressure, noteworthy
statistics, and the post-analysis best track.
Tropical Cyclone Reports (TCRs) are composed after a tropical cyclone has reached its end of life, and all pertinent data has been
gathered and analyzed. Once completed, the TCRs are posted to the
NHC TCR webpage
Seasonal Summary Table and Track Map
NHC and CPHC provide a seasonal summary table and a seasonal track map for the Atlantic and eastern and central
Pacific basins on each basin’s respective
TCR page
. These
seasonal summary tables and track maps are updated at least monthly, typically at the beginning of each month.
The seasonal summary tables and track maps are also updated once all of the TCRs are completed for each basin
at the conclusion of the season. The table includes the dates of occurrence for all of the season’s tropical
cyclones and basic meteorological statistics, such as the estimated peak intensity.
