This product, the Tropical Weather Outlook, briefly describes
significant areas of disturbed weather and their potential for
tropical cyclone formation during the next 5 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.

The Tropical Cyclone Update is a brief statement to inform of
significant changes in a tropical cyclone or to post or cancel
watches or warnings.  It is 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.
