What to Know
Severe thunderstorms moved into the region Tuesday afternoon and evening.
A First Alert is in effect from 1 to 9 p.m. Tuesday for the threat of downpours, flooding, hail and strong wind.
Thunderstorms may produce 1 to 2 inches of rain in a short period of time leading to flash flooding.
The NBC10 First Alert Weather Team has issued a First Alert due to severe thunderstorms packing strong winds, flooding and hail.
The First Alert is in effect until 9 p.m. Tuesday.
“Many neighborhoods will see the thunderstorms come through during the evening commute,” NBC10 First Alert Weather meteorologist Bill Henley said.
We experienced hot and humid conditions through the morning and into early afternoon where temperatures pushed into the low 90s. Then a cold front triggered strong storms during the afternoon and evening.
A Flash Flood Warning is in effect for Berks, Chester and Montgomery counties until 6:30 p.m. Flooding was reported in Pottstown and three people had to be rescued from flooded vehicles.
Flooding also caused problems for SEPTA with service suspended between Thorndale and Malvern in both directions. Inbound train #570 was canceled from Thorndale to Center City due to high flood waters.
Here is the timing for the storms:
3 to 6 p.m. – Lower Pennsylvania suburbs and I-95 Corridor including Philadelphia, Trenton and Wilmington
5 to 9 p.m. – South Jersey and southern Delaware

Thunderstorms may produce 1 to 2 inches of rain in a short period of time leading to flash flooding. Besides the downpours, thunderstorms could also generate damaging wind and hail.
A Flood Warning is in effect for western suburbs and a Flash Flood Watch is in effect for Philadelphia and the immediate Pennsylvania and New Jersey suburbs.
The storms caused the cancellation of community events from the suburbs (no Dining Under the Stars in Haverford) to the shore (no family movie night in Wildwood) so be sure to check with organizers before heading out to an outdoor event Tuesday night.
Showers and thunderstorms will move offshore overnight. Skies clear Wednesday with much lower humidity and highs in the mid 80s.
