Flood Watch After A Month's Worth Of Rain Fell Saturday

The Philadelphia region is under a flood watch Monday, as another round of heavy rainfall is expected this afternoon. The area is already heavily saturated, with some communities in the suburbs getting as much as four inches of rain in the past two days, according to data from the National Weather Service.

A flood watch is in place until 1 a.m. Tuesday. The same communities that got four inches of rain Saturday are now expected to get another round of rain today. A half inch to one and one-half inches are expected, the NWS said.

Be thankful it wasn't cold enough for the precipitation to be snow on Saturday. According to experts, each inch of rain equates to 13 inches of snow. That means some areas could have received 52 inches of snow.

AccuWeather confirms some communities received a month's worth of rain on Saturday night. In the Philadelphia region, the average rainfall for November is three inches all month, according to U.S. climate data.

Monday's additional heavy rainfall will only worsen the existing flooding threat, and could lead to more road closures up and down the I-95 corridor, AccuWeather notes. As of Monday at 11 a.m., there has been no flooding along the Delaware River, NWS maps show. You can see the levels here.

"Leaf clogged drains and coastal flooding could further exacerbate flooding issues. River flooding may continue into Wednesday or Thursday, well after the heavy rain has ended," the NWS said in its flood watch announcement.

The heavy rainfall Saturday caused roads to flood, and rivers and creeks to rise. At Tyler State Park in Newtown Township, the creek flooded the pedestrian bridge.
