The remnant moisture from what was one Tropical Storm Chantal will continue to push north today, bringing an elevated threat of flooding as far north as southeastern Pennsylvania and western New Jersey today. The threat also exists for much of Delaware and portions of eastern Virginia and Maryland.
Flood Watches go in effect today at 10am and remain up for most of the day for many counties across this region. They include , Hunterdon, Somerset, Middlesex, Monmouth, Mercer, Salem, Gloucester, Camden, Burlington, and Cumberland in New Jersey, Delaware, Philadelphia, Chester, Montgomery, and Bucks in Pennsylvania, Dorchester, Wicomico, Somerset, Westmoreland, Richmond, Northumberland, Lancaster, Middlesex, and Essex in Virginia, Cecil, Kent, Baltimore, Anne Arundel, St. Marys, Calvert, Queen Annes, Talbot, Caroline, and Harford in Maryland, and New Castle, Kent, and Sussex in Delaware.
The remnants of Chantal will move into the Mid Atlantic this morning bringing areas of heavy rain. The tropical airmass will bring generally 1-2″ of rainfall across the urban corridor but will have the potential to bring isolated amounts up to 5″ leading to flash flooding. The showers and thunderstorms will generally come to an end by 7 to 8 pm this evening with any residual flooding from showers today coming to an end during the overnight hours.
“Turn around, don’t drown; never drive through flood waters,” warns the National Weather Service.
As of 5 am today, the center of Tropical Depression Chantal was located near latitude 36.8 North, longitude 78.1 West. The depression is moving toward the northeast near 15 mph and this motion is expected to continue. Maximum sustained winds are near 30 mph with higher gusts. The estimated minimum central pressure is 1009 mb or 29.80″. The National Weather Service’s Weather Prediction Center, which has taken over responsibility for Chantal now that it has weakened and moved over land, says little change in strength is expected today.
In addition to the flood risk, life-threatening surf and rip current conditions are expected to continue at beaches along the U.S. east coast from northeastern Florida to the Mid-Atlantic states during the next day or so. The National Weather Service is encouraging people to stay out of the ocean until this threat passes.
Chantal was the third named storm of the 2025 Atlantic Hurricane Season and the second to impact the United States. The first, Barry, brought lethal flash floods to portions of Texas in recent days, claiming more than 80 lives.
The 2025 Atlantic Hurricane Season is expected to peak by September and run through to the end of November.
