700 PM EST Tue Nov 21 2023
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
1. Central Caribbean Sea (AL99):
Showers and thunderstorms associated with a weak low pressure over
the central Caribbean have diminished since yesterday. Nearby dry
air is forecast to prevent any additional development of the system
as it moves slowly westward during the next couple of days.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...near 0 percent.
2. Central Subtropical Atlantic:
An area of low pressure is expected to develop along a frontal
boundary over the central subtropical Atlantic within the next day
or so. This non-tropical low is forecast to move southeastward
across the central subtropical Atlantic over warmer sea surface
temperatures during the next few days, and environmental conditions
could allow for this system to gradually acquire tropical or
subtropical characteristics. A subtropical or tropical storm could
form by the latter part of this week or this weekend, as the system
turns northeastward by the weekend.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...medium...60 percent.
