If you have outdoor plans Monday, they may need to be put on hold.
The National Weather Service has issued a Flash Flood Watch for the Lehigh Valley for the afternoon and evening, when it says showers and thunderstorms will bring torrential downpours to the area.
“Rainfall amounts of 1 to 2 inches will be common, with localized totals of 3 to 4 inches possible,” the NWS said in a statement Sunday. “The bulk of these rainfall amounts could fall in a very short period. The heaviest rain will likely fall during the afternoon and early evening.”
Flash flooding of creeks, streams and roadways will be possible, especially in urban and poor drainage areas.
A Flash Flood Watch means conditions may develop that lead to potentially dangerous flash flooding.
Monday’s weather could affect the operation of the Hellertown Pool, which closed early twice last week due to weather conditions.
