This product, the Tropical Weather Outlook, briefly describes
significant areas of disturbed weather and their potential for
tropical cyclone formation during the next seven days. The issuance
times of this product are 5 AM, 11 AM, 5 PM, and 11 PM PDT. After
the change to standard time in November, the issuance times are
4 AM, 10 AM, 4 PM, and 10 PM PST.
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.
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 72 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-E", "Two-E",
"Three-E", 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 WTPZ61-65 KNHC, and under AWIPS header MIATCUEP1-5.
