The National Weather Service has issued a flash flood warning until 11:45 a.m. for much of the Philadelphia area as thunderstorms and heavy rains pound the region this morning.
The messy weather has wreaked havoc on mass transit. SEPTA is reporting delays on many of its regional rail lines, and the transit system announced about 8 a.m. that all service on the Manayunk/Norristown line has been suspended until further notice.
There are reports of delays of up to 45 minutes at Philadelphia International Airport.
After the flash flood warning expires at 11:45 this morning, a flash flood watch remains in effect until 4 p.m.
The National Weather Service briefly warned of the possibility of tornadoes in Chester County and north Delaware this morning, but no touchdowns were reported.
