More rain, thunderstorms and flooding are on their way to the Philadelphia area today.
The National Weather Service has issued a flash flood watch that will be in effect from 10 a.m. until midnight.
"Several bands of showers and thunderstorms with heavy rain are expected to occur today," the watch says.
Most areas are expected to see an inch to an inch and a half of rain, but three to four inches could fall in some places, forecasters say.
Forecasters expect the heaviest rain to hit Pennsylvania and Maryland by late morning, then spread to other parts of the watch area -- which covers the bulk of northern Delaware, northern Maryland, eastern Pennsylvania and western New Jersey -- this afternoon.
In Philadelphia, rain appears most likely between noon and 5 p.m., according to the weather service.
Flooding is expected in poor drainage areas, small streams and creeks.
Cities across the mid-Atlantic and Northeast are likely to experience showers and threats of flooding today, AccuWeather says.
The high temperature today is expected to reach 79 degrees.
Friday should be sunny, the weather service says, but the potential for yet more scattered showers and thunderstorms returns Saturday.
The showers come after Philadelphia saw record rainfall in both June and July.
