Severe thunderstorm watch expires; Flood Watch in effect for Philly region until midnight

PHILADELPHIA (CBS) -- Sunday was a Next Weather Alert Day as storms brought heavy rain and flash flooding to the Philadelphia region. 

The severe weather risk was very low as storms produced intense downpours. 

The main line of showers and storms moved through the area Sunday afternoon and evening.

The heavy rain hit areas northwest of the city like Berks and parts of Montgomery County hard. The rain caused flash flooding in Berks County displaced at least 39 residents. The Red Cross is currently assisting them at a shelter.  

A Severe Thunderstorm Watch for the region has expired. 

Parts of the Delaware Valley, including New Castle, Delaware, Philadelphia, lower Montgomery, lower Bucks, Salem Gloucester, Camden and northwestern Burlington Counties are under a Flood Watch until midnight, the National Weather Service said. 

The risk for both flash flooding and damaging winds exists across the region, but the highest risk for flash flooding is generally near and northwest of the I-95 corridor. 

Hundreds of flights have already been delayed or canceled at Philadelphia International Airport due the severe weather.
