For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

Northeastern Gulf of Mexico (AL91):
Showers and thunderstorms associated with an area of low pressure 
over the northeastern Gulf of Mexico have increased and become 
better organized during the overnight hours. Environmental 
conditions appear marginally favorable for additional development 
over the next day or so, and a short-lived tropical depression or 
storm could form over that time span as the system meanders over the 
northeastern Gulf of Mexico. However, by this weekend environmental 
conditions are forecast to become unfavorable for additional 
development as the system drifts southward, likely remaining 
offshore over the Gulf of Mexico. An Air Force Reserve Hurricane 
Hunter aircraft is scheduled to investigate the system later today, 
if necessary.

Regardless of development, locally heavy rainfall could occur over 
portions of the Florida Peninsula through this weekend. Additional 
information on the rainfall and flooding potential can be found in 
products issued by your local National Weather Service forecast 
office and Excessive Rainfall Outlooks issued by the Weather 
Prediction Center.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 7 days...medium...50 percent.

Today marks the first day of the Atlantic hurricane season, which 
will run until November 30. The long-term averages for the number of 
named storms, hurricanes, and major hurricanes are 14, 7, and 3, 
respectively.

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 2 AM, 8 AM, 2 PM, 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.

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.  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 WTNT61-65 KNHC, 
and under AWIPS header MIATCUAT1-5.
