200 PM EDT Tue Sep 28 2021

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

The National Hurricane Center is issuing advisories on Hurricane 
Sam, located several hundred miles east of the northern Leeward 
Islands.

1. Showers and thunderstorms remain disorganized in association with a 
a broad area of low pressure located several hundred miles 
southwest of the Cabo Verde Islands. Environmental conditions are 
conducive for gradual development, and a tropical depression is 
likely to form during the next couple of days while the system 
moves slowly westward to west-northwestward over the central 
tropical Atlantic.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...80 percent.

2. A broad area of low pressure located over the far eastern Atlantic 
several hundred miles south-southeast of the Cabo Verde Islands is 
producing a large area of showers and thunderstorms.  This shower 
activity is gradually becoming better organized, and a tropical 
depression is expected to form in a day or so while the disturbance 
moves west-northwestward at 10 to 15 mph over the eastern tropical 
Atlantic.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.

3. A well-defined low pressure area associated with the remnants of 
Peter located about 400 miles east-northeast of Bermuda is producing 
gale-force winds. The associated showers and thunderstorms have 
become less organized during the past few hours, and the chances of 
this system becoming a short lived tropical depression or storm 
appear to be decreasing. This system is expected to move 
northeastward at about 10 mph into a region of very strong 
upper-level winds on Wednesday.  Additional information on this 
system can be found in High Seas Forecasts issued by the National 
Weather Service.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...40 percent.
