Tropical Weather Outlook NWS National Hurricane Center Miami FL 200 PM EDT Mon Aug 22 2022

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

  1. Eastern Tropical Atlantic: Showers and thunderstorms have become a little more concentrated today in association with a tropical wave located a few hundred miles west of the Cabo Verde Islands. Environmental conditions could support some slow development of this system while it moves westward to west-northwestward at around 10 to 15 mph across the tropical Atlantic during the next several days. * Formation chance through 48 hours…low…10 percent.
  • Formation chance through 5 days…low…30 percent.


A tropical wave extends along 28W from 09 to 22N, moving W at 15 kt. A 1012 mb low pressure is analyzed along the wave axis near 16N. Scattered moderate convection is noted from 15N to 17N, between 27W and 30W. Environmental conditions could support some slow development of this system while it moves W-WNW at 10-15 kt across the eastern and central tropical Atlantic for the next several days. Currently, this system has a low chance of tropical cyclone development through 5 days.

A central Atlantic tropical wave extends along 48W from 07N to 21N, moving W at 15 kt. A recent scatterometer pass found a subtle shift in the surface winds, though convection remains limited near the wave axis.

A central Caribbean tropical wave extends along 78W from 06N to 20N, moving W at 15 kt. Isolated showers and thunderstorms are observed throughout the central Caribbean with the strongest convection south of Cuba.
