CHESTER COUNTY, PA — A National Weather Service Flash Flood Watch is in effect from September 8, 04:00 PM EDT until September 9, 02:00 AM EDT for eastern Chester County in Pennsylvania.
From this afternoon through late tonight, thunderstorms with heavy rain are forecasted to move through the region this evening. Given the very saturated soils from recent heavy rain events, additional brief heavy rainfall of one to two inches may quickly lead to flooding of flood-prone and other low-lying areas due to rapid runoff.
Today: A chance of showers and thunderstorms, mainly after 3pm. Some of the storms could produce heavy rainfall. Mostly sunny, with a high near 83. South wind 5 to 15 mph, with gusts as high as 30 mph. Chance of precipitation is 30%. New rainfall amounts of less than a tenth of an inch, except higher amounts possible in thunderstorms.
