Developing Coastal Storm to Threaten East Coast With Coastal Flooding and High Winds Sunday Into Monday

Forecasters warn that elevated astronomical tides will intensify inundation during multiple high-tide cycles.

Overview

  • A low forming off the Southeast coast Friday is projected to track north with the National Weather Service calling for significant impacts from later Saturday through Monday.
  • Coastal flood watches and warnings are posted from Florida’s Space Coast and the Carolinas to New Jersey, with Hampton Roads expecting moderate to major tidal flooding at Sunday afternoon’s high tide.
  • Onshore wind gusts are forecast to reach roughly 30–50 mph along many shorelines with 55–60 mph possible at exposed capes and beaches, raising risks of beach erosion and scattered power outages.
  • Rainfall near the coast could total 1–3 inches with localized 3–5 inches in some model solutions, while drier antecedent conditions inland lower the widespread flash-flood risk.
  • Marine hazards include gale to near storm-force winds offshore, very rough surf and a high rip-current risk, as Tropical Storm Jerry strengthens well out to sea with no U.S. land threat.
