Another round of thunderstorms is headed for the Philadelphia area, but they are not expected to be as severe as had been projected in earlier forecasts.

The system bringing severe storms has shifted farther south, with the main action now likely to hit the lower Chesapeake Bay, according the National Weather Service Storm Prediction Center.

The thunderstorms that are forecast to arrive in the region in the late afternoon could produce gusty winds and heavy rains.

The National Weather Service has issued a flash flood watch, effective starting at 2 p.m., for Philadelphia, Delaware, Chester, Montgomery, and Bucks Counties in Pennsylvania and for Camden, Gloucester, Burlington, and Ocean Counties across the river.

The daytime high temperature is expected to be around 83 degrees in Philadelphia and at the Shore. Dew points in the 70s will make it feel muggy. There’s a moderate risk of rip currents, which means beach goers should swim within sight of a lifeguard, and never swim alone or at night.

The stormy weather could cause problems for anyone hoping to view the Perseid meteor showers.

The weather for the rest of the work week looks unsettled, with a chance of thunderstorms in the forecast for every day through Friday. Daytime highs will be in the low- to mid-80s.

Saturday will be warmer, with a high of 88 expected under partly sunny skies.
