10-Day Tropical Monitor

All-Clear the next 10 days BUT tropical waves are emerging Fig. 1: Satellite view of the North Atlantic basin. Discussion: A tropical wave moving across the Bahamas will merge with a cold front along the Atlantic Seaboard TUE/WED enhancing already heavy rainfall. In the tropics heavy convection is starting to percolate and tropical activity for August is ahead but northing important over the next 10 days in the North Atlantic basin. The North Atlantic is warming ahead of peak of season (Fig. 2). Fig. 2: NOAA/NHC weekly SSTA analysis for the North Atlantic basin. The subtropics are very warm. The tropics are normally warm although cool off the West Coast of Africa.
