Southeastern Pennsylvania, including Berks County, is under a flash flood watch starting Wednesday afternoon and running through Thursday morning, according to the National Weather Service.
The National Weather Service issued the hazardous weather outlook for Berks, Chester, Montgomery, Bucks, Delaware and Philadelphia counties, as well as for the Lehigh Valley and western New Jersey. A line of thunderstorms is expected to move through the area in the afternoon, bringing up to 2 inches of rainfall to an area that was hit in the past week with remnants of Hurricane Ida.
The storms are also expected to bring high winds with the possibility of tornadoes, according to the National Weather Service.
“Given the very saturated soils from recent heavy rain events, additional brief heavy rainfall of 1 to 2 inches may quickly lead to flooding of flood prone and other low-lying areas due to rapid runoff,” the agency said in its warning.
Wednesday’s forecast calls for a high of 85 degrees. Until the rain starts in the afternoon, the day should be otherwise sunny with some clouds.
Flash flooding usually occurs within three to six hours of heavy rain. It can lead to rapidly moving water in creeks and rivers as well as streets and underpasses.
The American Red Cross has these tips for staying safe:
- Turn around if you’re driving on a road that gets flooded and find another route.
- If your car gets caught in the flood waters, get out and find higher ground right away.
- Keep children and pets out of the water.
- Take extra precautions at night, when it’s harder to see flood danger.
The flash flood watch runs through 2 a.m. Thursday.
