Tropical Storm Gabrielle Expected to Reach Hurricane Strength by Sunday, Track to Pass East of Bermuda

Lower wind shear is improving conditions for strengthening with guidance keeping the system well offshore of the United States.

Overview

  • As of the 5 p.m. AST Friday advisory, Gabrielle had sustained winds near 50 mph and was moving west-northwest at about 12 mph.
  • Forecasts call for intensification over the weekend, with the National Hurricane Center indicating hurricane strength could be reached by Sunday.
  • Reliable model guidance shows the center passing at least about 130 nautical miles east of Bermuda, where there remains a 20% to 25% chance of tropical-storm-force winds.
  • NHC forecasters expect no direct impacts to the U.S., though swells, rip currents and marine hazards are likely over portions of the Atlantic.
  • Separately, a disturbance south-southwest of the Cabo Verde Islands carries about a 20% chance of development over the next seven days, according to the NHC.
