AccuWeather: Flash Flood Watch Into Late Tonight

PHILADELPHIA (WPVI) -- A FLASH FLOOD WATCH is in effect through late tonight for the entire Delaware Valley, including the Lehigh Valley (which was added overnight). Occasional storms and showers could bring heavy downpours which could cause street flooding. Flashy creeks and streams could also be affected. Do not walk or drive through flooded areas. Fast rising water could lead to life-threatening situations.

It's a mostly cloudy Friday with occasional drenching showers and storms that could lead to flash flooding. The high is 81. It's warm and humid.

TONIGHT: Look for mostly cloudy and humid conditions with more showers and thunderstorms possible, along with isolated downpours that could lead to flash flooding. The low is 71.
