Overview

• Low pressure developing off the Carolinas is forecast to lift north Sunday into Monday, bringing periods of heavy rain, strong onshore winds and coastal flood concerns from the mid-Atlantic into New England.
• Coastal flood watches are posted in parts of Southern New England starting Sunday, with models pointing to 1–4 inches of rain (locally higher near the coast) and peak gusts commonly 30–60 mph.
• Hampton Roads forecasters expect widespread weekend downpours with the worst tidal flooding near Sunday afternoon; the Carolinas’ coast faces 30–40 mph gusts onshore and gale conditions offshore.
• South Florida is under a flash-flood risk Friday with slow-moving downpours capable of 3–5 inches in spots, compounded by king tides and dangerous rip currents, before a drier, cooler pattern arrives Sunday.
• Out West, the National Weather Service projects measurable rain and a sharp cool-down in Southern California Monday–Tuesday, with up to 1–2 inches possible in parts of Los Angeles and Ventura counties, while Tropical Storm Jerry strengthens over the Atlantic and turns away from the U.S.
