The weather system is expected to bring 1 to 2 inches of rain with isolated amounts closer to 3 inches in some areas. The rain showers and thunderstorms began moving in early Thursday and will continue through the day, according to the National Weather Service.
Forecasters warn that the already wet ground along with swollen streams and Delaware River will increase the risk for flooding. The weather system is the third rain event in the last week.
The National Weather Service hydrograph forecast shows the Delaware River and Neshaminy Creek will remain below flood level but higher than average following the weather system.
