Forecasters See Dexter Rebound Post-Tropical as Atlantic Development Odds Climb

Dexter’s shift into post-tropical status is expected to boost its strength over the North Atlantic, prompting forecasters to update formation probabilities for two other systems.

A map from the National Hurricane Center shows meteorologists monitoring three disturbances, including one tropical storm, in the Atlantic Ocean.

Overview

  • Dexter has regained strength with 45 mph sustained winds about 405 miles south-southeast of Halifax and is forecast to intensify over the next 48 hours as it transitions into an extratropical cyclone.
  • A broad low-pressure system several hundred miles off the Southeast U.S. coast now carries a 40 percent chance of forming into a tropical depression by this weekend as it slowly drifts westward then turns northward.
  • A tropical wave nearing the central Atlantic holds a 50 percent likelihood of cyclone formation later this week as it moves west-northwestward from its position off Africa’s coast.
  • In the eastern Pacific, Tropical Storm Henriette is tracking west-northwest with 50 mph winds and is expected to weaken slightly before holding steady well clear of any land.
  • The National Hurricane Center has not issued any watches or warnings, emphasizing that none of the monitored tropical activity poses an immediate land threat.
