Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM 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 
Depression Peter, located a couple of hundred miles northeast 
of Puerto Rico, and on Tropical Storm Rose, located about 1000 
miles west-northwest of the Cabo Verde Islands. 

Showers and thunderstorms associated with a tropical wave located 
several hundred miles southwest of the Cabo Verde Islands have 
increased since this morning and are beginning to show signs of 
organization. Recent satellite wind data also indicate that a broad 
area of low pressure has formed, but the system lacks a well-defined 
center. Environmental conditions are expected to remain conducive 
for additional development, and a tropical depression is likely to 
form within the next 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 executes a 
small counter-clockwise 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 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.
