Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Mon Sep 20 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 150 miles northeast 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 
several hundred miles south of the Cabo Verde Islands continue to 
show some signs of organization, although recent satellite wind data 
indicate that the system lacks a surface circulation. Upper-level 
winds, however, are expected to become conducive for further 
development during the next day or two, 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...40 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 by the 
middle of this week as it moves slowly southeastward over warmer 
waters across the north-central Atlantic Ocean, before it moves 
northward over cooler waters over the weekend.  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.

High Seas Forecasts issued by the National Weather Service can be 
found under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and
