Overview
- The National Weather Service issued multiple county-specific flash flood warnings and broader flood watches on Friday and Saturday after Doppler radar indicated slow-moving storms dumping intense rain over the region.
- Radar and NWS bulletins recorded common short-term totals of 1 to 1.5 inches with localized storm rates of 1.5 to 3 inches per hour and 24-hour totals near 5 inches in spots such as Elizabethtown.
- Local crews and viewer video documented urban flooding, water pouring from elevated lots into streets, hazardous road conditions, reports of lightning strikes to homes, and trees down on vehicles in the Philadelphia area.
- Forecasters warned that saturated ground amplifies runoff and flash-flood potential, advised motorists to 'turn around, don't drown' when encountering flooded roads, and said storms should taper overnight with a heat ridge bringing drier weather next week.
- Flood watches remain in effect in parts of the affected areas as officials urged people to avoid low-lying and poorly drained roadways and to seek shelter during sudden heavy downpours.
