Weather Service Calls for Flash Flooding

The National Weather Service in Mount Holly has issued a flash flood watch for the surrounding area including Bucks and Montgomery counties.

The watch is in effect from 10 p.m. this evening through Wednesday afternoon.

According to the Weather Service, a complex low pressure system will move from the Ohio Valley into our region later tonight and produce a copious amount of rain over a rather short time period. Rain will be heavy at times tonight and early Wednesday morning as the system wraps up and moves to our northeast. Widespread rainfall amounts of one to three inches are possible in the watch area with even higher amounts from isolated thunderstorms.

Impacts could include small stream, poor drainage, urban area, basement, and roadway flooding. The larger rivers, including the Delaware, should be able to take the excessive rainfall amounts but they may run high and a few may possibly approach flood stage.

Here’s the forecast through Thanksgiving:

Late Afternoon: Rain. High near 53. East wind around 7 mph. Chance of precipitation is 90%. New rainfall amounts between a tenth and quarter of an inch possible.

Tonight: Rain, with thunderstorms also possible after 1am. Some of the storms could produce heavy rainfall. Low around 51. East wind 7 to 9 mph becoming south. Chance of precipitation is 100%. New rainfall amounts between 1 and 2 inches possible.

Wednesday: Showers and possibly a thunderstorm before 9am, then showers likely. High near 62. North wind between 7 and 15 mph. Chance of precipitation is 90%. New rainfall amounts between a half and three quarters of an inch possible.

Wednesday Night: Mostly cloudy, then gradually becoming clear, with a low around 35. North wind between 8 and 17 mph, with gusts as high as 34 mph.
