The NBC10 First Alert Weather Team issued a First Alert for pockets of heavy rain and scattered storms. People were told to expect wet roads during your drive and the potential for flooding in areas where downpours take place. The First Alert expired Tuesday afternoon.
Leftover pockets of rain will still be lingering into Wednesday, however they won't bring the major road closures and disruptions seen earlier on Tuesday.
Before daybreak Tuesday, parts of Berks, Chester, Delaware and Montgomery saw heavy downpours. The National Weather Service issued a flood advisory in those areas due to "excessive rainfall." A flash flood warning was then put in effect until 11 a.m. for parts of Chester, Delaware, Montgomery and Philadelphia counties.
The rain fell so fast in Montgomery County Tuesday morning that part of the eastbound Schuylkill Expressway (Interstate 76) flooded, causing major delays near the merge for Route 202.
The worst of the downpours pushed through the northern and western suburbs during the morning and were drenching Philadelphia, Delaware and South Jersey by midday. The worst of the heavy rain was gone by late afternoon.
One to 3 inches of rain are expected to fall before the system finally moves out Wednesday, with the highest amounts coming during the day on Tuesday. As of late Tuesday morning, more than 2.5 inches of rain had already fallen in Coatesville, Pennsylvania, and Millville, New Jersey.
The highest rainfall total for the region, as of Tuesday afternoon, was reported at the Welcome Center along Interstate 95 in Delaware County, coming in at 4.67 inches at 3:05 p.m.
Meteorologists Michelle Rotella and Steve Sosna spoke about the soaking they experienced Tuesday morning. A good bet was to ride out the worst of the rain until later in the day and plan on having a change of clothes, if needed.
The recent drought watch actually helped us in not seeing more widespread flooding from this rain event.
Flooding wasn't the only concern as southern parts of New Jersey and Delaware were also under a risk for severe thunderstorms into Tuesday afternoon. A tornado can't be ruled out, as evidenced by the earlier warning in Cape May County.
Cooler temperatures have settled in due to clouds and rain with highs only in the 70s Tuesday and Wednesday.
The on-and-off rainfall is expected to taper out by late Wednesday. Sunshine returns Thursday and Friday, with highs back in the lower 80s.
