Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 AM EDT Tue Sep 21 2021

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

The National Hurricane Center is issuing advisories on Tropical 
Storm Peter, located about 100 miles north of the northern Leeward 
Islands, and on Tropical Storm Rose, located over the eastern 
tropical Atlantic Ocean.

1. Showers and thunderstorms associated with a tropical wave located a 
few hundred miles south-southwest of the Cabo Verde Islands continue 
to show some signs of organization. Environmental conditions are 
expected to become more conducive for development, and a tropical 
depression is likely to form later this week while the system moves 
westward at 10 to 15 mph across the eastern and central tropical 
Atlantic Ocean.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...high...80 percent.

2. A storm-force, non-tropical low pressure system, the remnants of 
Odette, is located several hundred miles southeast of Newfoundland.  
This low could acquire some subtropical characteristics during the 
next few days while it moves slowly southeastward over warmer waters 
across the north-central Atlantic Ocean.  However, the system is 
expected to turn northward back over cooler waters this weekend, 
which should end its chances of becoming a subtropical storm. 
Additional information on this system, including storm warnings, can 
be found in High Seas Forecasts issued by the National Weather 
Service.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...30 percent.
