POTTSTOWN PA – A flood watch has been declared for the Pottstown area from the period from Wednesday at noon through Thursday at 5 p.m. (Feb. 3-4, 2016), when potentially heavy rain and unseasonably warm temperatures are likely to increase water levels in the Schuylkill River and area creeks, streams and runs, according to the National Weather Service.
A flood watch means there is a potential for flooding based on current forecasts. It is in effect for all of western Montgomery County, and specifically for Pottstown and Collegeville among several other boroughs, the weather service said.
The water level in the Schuylkill River at Pottstown was measured this morning (Tuesday, Feb. 2) at 2 a.m. as 2.65 feet (as shown by the blue line on the graph above). It is expected to rise to as high at 9.7 feet (shown by the thin maroon line) by Thursday morning at around 8 a.m. Flood stage of the river at Pottstown is 12.5 feet.
Driving also may be difficult this morning in some areas due to dense fog, it added in a “hazardous weather outlook” advisory.
Temperatures could reach a high of 45 degrees today, 60 degrees on Wednesday, and 45 again on Thursday, forecasters predicted. The warmth is expected to cause significant snow melt, and that will be coupled with what the weather service said was a “100-percent chance of precipitation” with rainfall accumulation in amounts “between three quarters and one inch possible.”
