The Saucon Valley is under a Flash Flood Watch issued by the National Weather Service.
In a statement Sunday, the NWS said the watch will be in effect from 6 p.m. through late Sunday evening for Lehigh, Northampton and other counties in eastern Pennsylvania and western New Jersey.
“Showers and thunderstorms with heavy rain will move through eastern Pennsylvania, northeastern Maryland, Delaware and New Jersey during the balance of today and into tonight,” the statement said. “Rainfall amounts up to 2 to 4 inches are possible. The heavy rain will fall in a short amount of time and it may result in flash flooding.
Heavy rain falling in a short period of time could result in rapidly rising levels of streams and creeks and in areas of poor drainage, particularly because the ground is already saturated from torrential rain that fell Saturday afternoon and evening.
“Significant roadway flooding may occur,” the National Weather Service said.
A Flash Flood Watch means flash flooding is possible. In the event of flooding, a Flash Flood Warning will be issued for any affected location.
Motorists are reminded never to drive through flood waters, as the water may be deeper than they think it is. A vehicle can easily become trapped in flood waters, endangering both its occupants and those who come to their rescue.
