Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 AM EDT Wed Sep 22 2021

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

The National Hurricane Center is issuing advisories on Tropical 
Depression Peter, located a couple of hundred miles north-northeast 
of Puerto Rico, and on recently downgraded Tropical Depression 
Rose, located about 1000 miles west-northwest of the Cabo Verde 

Showers and thunderstorms are becoming better organized in 
association with a tropical wave located several hundred miles 
southwest of the Cabo Verde Islands.  However, satellite wind data 
indicate that the system still lacks a well-defined center. 
Environmental conditions are expected to remain conducive for 
additional development, and a tropical depression is likely to form 
in a day or two while the system moves westward at 10 to 15 mph 
across the eastern and central tropical Atlantic Ocean.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 5 days...high...90 percent.

A gale-force, non-tropical low pressure system, the remnants of 
Odette, is located about 500 miles west of the westernmost Azores. 
This low could acquire some subtropical characteristics over 
marginally warm waters during the next few days while it makes a 
counter-clockwise loop over the north-central Atlantic Ocean. 
However, by the weekend, this system is expected to move into an 
environment of strong upper-level winds.  Additional information on 
this system, including gale warnings, can be found in High Seas 
Forecasts issued by the National Weather Service.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...medium...50 percent.
