100 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 small area of low
pressure over the central Caribbean have not become any better
organized today. Nearby dry air is forecast to prevent additional
significant development of the system as it moves slowly westward
during the next few days.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...10 percent.
2. Central Subtropical Atlantic:
An area of low pressure is expected to develop along a frontal
boundary over the central subtropical Atlantic later today or
tonight. 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
appear conducive for this system to gradually acquire tropical
characteristics. A subtropical or tropical storm could form by the
latter part of this week, as the system continues moving eastward
followed by a turn northeastward by the weekend.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...medium...60 percent.
