One named cyclone, Alberto, already formed this year in May. The
next named storm that forms this season will be called Beryl.

This product, the Tropical Weather Outlook, briefly describes
significant areas of disturbed weather and their potential for
tropical cyclone formation during the next five days. The
issuance times of this product are 2 AM, 8 AM, 2 AM, and
8 PM EDT. After the change to standard time in November, the
issuance times are 1 AM, 7 AM, 1 PM, and 7 PM EST.

A Special Tropical Weather Outlook will be issued to provide
updates, as necessary, in between the regularly scheduled
issuances of the Tropical Weather Outlook. Special Tropical
Weather Outlooks will be issued under the same WMO and AWIPS
headers as the regular Tropical Weather Outlooks.

A standard package of products, consisting of the tropical cyclone
public advisory, the forecast/advisory, the cyclone discussion,
and a wind speed probability product, is issued every six hours
for all ongoing tropical cyclones. In addition, a special
advisory package may be issued at any time to advise of
significant unexpected changes or to modify watches or warnings.

The National Hurricane Center (NHC) has the option to issue
advisories, watches, and warnings 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 48 hours. For
these land-threatening “potential tropical cyclones”, NHC will issue
the full suite of advisory and watch/warning products. Potential
tropical cyclones share the naming conventions currently in
place for tropical depressions, being numbered from a single list
(e.g., “One”, “Two”, “Three”, etc.).

The Tropical Cyclone Update is a brief statement to inform of
significant changes in a tropical cyclone, to post or cancel
watches or warnings, or to provide hourly position updates between
intermediate advisories when the storm center is easily followed
by radar. The Tropical Cyclone Update is also used in lieu of
or to precede the issuance of a special advisory package.
Tropical Cyclone Updates, which can be issued at any time, can
be found under WMO header WTNT61-65 KNHC, and under AWIPS header
MIATCUAT1-5.
