| Tropical Cyclone Report (TCR) |
The Tropical Cyclone Report (TCR) is a post-event
overview of a tropical cyclone comprised of a
narrative describing the overall storm and a
detailed listing of 6-hourly location and
intensity data in both text and graphic format.
The National Hurricane Center (NHC) and the
Central Pacific Hurricane Center (CPHC) prepare
TCRs within 90 days of any tropical cyclone that
occurs within their respective Area of
Responsibility (AOR). NHC issues TCRs for
tropical cyclone activity in the Atlantic and
eastern north Pacific (north of the equator and
east of 140 degrees west longitude) basins. CPHC
issues TCRs for tropical cyclone activity in the
central North Pacific (north of the equator
between 140W and 180 degrees west longitude)
basin.

| Tropical Cyclone Forecast Advisories (TCM) |
The is a text product prepared by the National
Hurricane Center (NHC) and the Central Pacific
Hurricane Center (CPHC) for tropical cyclones in
their respective basin of responsibility. TCMs
are issued for the Atlantic and eastern Pacific
basins by the NHC. TCMs are issued for the
central Pacific by the CPHC. The product title
depends on the intensity of the tropical cyclone,
to include: Tropical Depression Advisory, Tropical
Storm Advisory, Hurricane/Typhoon Advisory. This
product is also issued for subtropical storms.

| Tropical Cyclone Position Estimate (TCE) |
The Tropical Cyclone Position Estimate (TCE) is an
event-driven (non-routinely issued) alphanumeric
product comprised of information concerning the
location of the center of a tropical cyclone as
determined by land-based radar fixes. The
National Hurricane Center (NHC), the Central
Pacific Hurricane Center (CPHC), and the Weather
Forecast Office (WFO) Guam prepare TCEs on an
event-driven basis for tropical cyclone activity
within the effective range of land base radars.
NHC issues TCEs for tropical cyclone activity in
the Atlantic and eastern north Pacific (north of
the equator and east of 140 degrees west
longitude) basins. CPHC issues TCEs for tropical
cyclone activity in the central North Pacific
(north of the equator between 140W and 180W
longitude) basin and WFO Guam for the northwest
Pacific (U.S. territories or the Republic of
Palau, Federated States of Micronesia, and
Republic of the Marshall Islands north of the
equator and from 130W - 180W longitude).

| Tropical Cyclone Summary-Fixes (TCS) |
The TCS is an alphanumeric product which the
Central Pacific Hurricane Center (CPHC) provides
when there is a classifiable (using the Dvorak
technique) tropical cyclone activity in the north
central or south Pacific. The TCS is a
satellite-based estimate of tropical cyclone
location, movement, and intensity with a brief
remarks section. Pacific Region's CPHC prepares
TCS for a portion of their area of responsibility
(AOR). The AORs for CPHC/Weather Forecast Office
(WFO) Honolulu (CPHC is collocated with the
Weather Forecast Office Honolulu) varies
depending upon the program (tropical cyclone,
aviation, marine, public, and satellite). For
TCS program, CPHC's AOR is the area north of the
equator between 140W - 180 longitude and from the
equator to 25 S latitude between 120W to 160E.

| Tropical Cyclone Update (TCU) |
The TCU is a brief alphanumeric text product which
the National Hurricane Center (NHC) and the
Central Pacific Hurricane Center (CPHC) issue to
inform customers of unexpected or sudden changes
in a tropical cyclone or to post or cancel
watches and warnings. NHC and CPHC issue TCUs on
an event-driven basis in lieu of or preceding
special advisories.

| Tropical Weather Outlook (TWO) |
The TWO is a text product prepared by the National
Hurricane Center and Central Pacific Hurricane
Center for their respective areas of
responsibility. It is a general assessment of
activity in the tropics, pertaining to tropical
cyclone formation by providing possible areas
where tropical cyclones could development.

| Tropical Weather Summary (TWS) |
The TWS is a monthly narrative alphanumeric
product which the National Hurricane Center (NHC)
and the Central Pacific Hurricane Center (CPHC)
issue to summarize tropical cyclone activity
during the previous month. NHC issues summaries
which cover tropical cyclone activity over the
Atlantic and eastern north Pacific (north of the
equator and east of 140W longitude) basins. CPHC
issues summaries which cover tropical cyclone
activity over the central North Pacific (north of
the equator between 140W and 180W longitude)
basin. The centers issue new summaries the first
day of each month from June through December. The
last TWS of the tropical cyclone season (December
issuance) covers activity during the entire
season from June through the end of November.

| Hurricane/Typhoon Local Statement (HLS) |
The HLS is an alphanumeric product alerting the
public of present and anticipated local tropical
cyclone affects. Coastal and selected inland
Weather Forecast Offices issue HLSs when their
County Warning Area and adjacent coastal waters
is affected by a tropical cyclone watch/warning
or evacuation orders.

| Tropical Cyclone Danger Area |
The Tropical Cyclone Danger Area is a graphical
marine product depicting a tropical cyclone's
track (out to 72 hours) and shades in a danger
area determined by adding 100, 200, and 300
nautical miles plus the 34 knot wind radii to the
24-, 48-, and 72- hour forecast position
respectively in the Atlantic and east Pacific.
For the central Pacific the shaded danger area
will varying in width dependent upon the
hurricane specialists confidence in the track and
the length of the 34 knot wind radii. In
addition, areas of possible tropical cyclone
genesis (out to 36 hours) are included and
depicted as either a circular, rectangle, oval,
or polygon shaped area. The product is prepared
by the TPC and covers the entire Atlantic north
of the equator and the Pacific north of the
equator from the Mexican and Central America
coast west to 140 west. CPHC prepares a
separate chart for 140 west to the International
Dateline north of the equator.

| Tropical Cyclone Discussion (TCD) |
The TCD is a text product prepared by the National
Hurricane Center (NHC) and Central Pacific
Hurricane Center (CPHC) for tropical cyclones in
their respective basin of responsibility. The
TCD provides forecasters' reasoning behind the
analysis and forecast of a tropical cyclone.
Discussions include prognostic reasoning;
objective techniques employed; NHC, CPHC, and
Hydrometeorological Prediction Center guidance
used; coordinated 12-, 24-, 36-, 48-, 72-, 96-,
and 120-hour tropical cyclone forecast positions
and maximum sustained wind speed forecasts; other
meteorological decisions; and plans for watches
and warnings. This product is also issued for
subtropical storms.

| Tropical Cyclone Storm Surge Probabilities |
The product consists of a graphic and GRIB2 data
for creating the graphic for the Gulf of Mexico
and Atlantic coastal areas of the continental
United States. The graphic shows probabilities,
in percent, of storm surge exceeding
5 feet. This storm surge graphic is based upon
an ensemble of Sea, Lake, and Overland Surge from
Hurricanes (SLOSH) model runs using the National
Hurricane Center (NHC) official advisory and
accounts for track, size, and intensity errors
based on historical errors.
