Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 AM EDT Fri Oct 27 2023

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

1. Northwestern Atlantic (Post-Tropical Cyclone Tammy):
A strong extratropical cyclone (formerly Tammy) associated with an 
occluded front is located a few hundred miles east of Bermuda. This 
system is forecast to become separated from the front later today, 
and environmental conditions are forecast to become more conducive 
over the northwestern Atlantic to the east of Bermuda through 
Saturday. Regardless of tropical redevelopment, the system is likely 
to bring gusty winds and heavy rainfall to Bermuda during the next 
couple of days. Interests on Bermuda should monitor the progress of 
this system. For additional information, including storm and gale 
warnings, see High Seas Forecasts issued by the National Weather 
Service and products from the Bermuda Weather Service.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 7 days...medium...50 percent.

2. Western Caribbean Sea:
A broad area of low pressure is forecast to develop over the 
southwestern Caribbean Sea during the next few days. Environmental 
conditions could support some slow development of this system early 
next week while it moves generally northward over western or central 
portions of the basin. 
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...30 percent.
