PHILADELPHIA, Pa. — A First Alert Weather Advisory is in effect across the Philadelphia region, with forecasters warning of heavy rain, gusty winds, and possible localized flooding throughout the day Thursday.
Meteorologists say the storm system will bring 1 to 3 inches of rainfall across the Delaware Valley, with the heaviest rain expected during the morning and evening commutes.
Wind gusts could reach 45 to 50 mph, creating hazardous travel conditions, especially on elevated roadways, bridges, and areas prone to poor drainage.
