Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 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-northwest of the northern 
Leeward Islands, and on Tropical Storm Rose, located over the 
eastern tropical Atlantic Ocean.

Showers and thunderstorms are currently somewhat limited associated 
with a tropical wave located a few hundred miles southwest of the 
Cabo Verde Islands. However, environmental conditions are expected 
to become more conducive for development, and a tropical depression 
is likely to form by Thursday or Friday 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...90 percent.

A storm-force, non-tropical low pressure system, the remnants of 
Odette, is located about 700 miles west-northwest of the westernmost 
Azores. This low could acquire some subtropical characteristics over 
marginally warm waters during the next few days while it executes a 
small cyclonic loop over the north-central Atlantic Ocean. However, 
by the end of the week, this system is expected to encounter more 
hostile environmental conditions. 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...20 percent.
* Formation chance through 5 days...medium...40 percent.
