<p>Forecast probabilities of winds associated with tropical cyclones are
needed to support operations at WFOs with marine responsibility over the
coastal, offshore and high seas zones and WFOs which may be impacted by
land falling cyclones.</p></td>
</tr>
<tr class="even">
<td colspan="20"><p>15. KNOWN OR PROPOSED SOLUTION</p>
<p>The Tropical Prediction Center (TPC) issues forecast probabilities of
wind associated with tropical cyclones. These products are event driven,
and will be issued from the TPC when a tropical cyclone is forecast to
develop within or enter the U.S. and its territories forecast area of
responsibility in the Atlantic and Pacific Oceans. Occasionally wind
probability products are issued when tropical cyclone conditions warrant
the issuance of special forecast advisories.</p>
<p>Forecasters preparing products for marine, coastal, and inland zones
will use these probabilistic wind products as guidance for operational
product issuance. These products will also be disseminated to the public
via the NOAAPort.</p>
<p>Products will be disseminated for a maximum of four forecast cycles
per day at the synoptic times 00, 06, 12, and 18 UTC. For each wind
category threshold, 4 products per day will be prepared for the 00, 12,
24, 36, 48, 60, 72, 84, 96, 108, 120 forecast periods. These products
are depictions of probability expressed in percentage over three wind
thresholds; 34 knots, 50 knots, and 64 knots. Areas of wind above these
thresholds associated with extra-tropical cyclones will be set to
zero.</p>
<p>The products will be issued in the AWIPS grid 231 at 0.5 degrees
horizontal resolution, in Grib 1 format until 2005. TPC expects to
transition to use Grib 2 format for the products in 2005.</p></td>
