The flood threat

Snow is gone, but heavy rains may pose a flood threat.

The flood threat


The temperature reached the big 6-0 yesterday, and the snowpack is all but history in the immediate Philadelphia area. Nonetheless, the National Weather Service advises that heavy rains could set off some flooding later in the week.

The water content of the snowpack in the headwater regions of the Schuylkill and Delaware River remains impressive, although some of that should get wrung out during the next two days.

This will be a slow-motion storm, with rain possible from late Thursday into Saturday. The fact that it will be a prolonged event, however, is not necessarily a bad thing.

What matters in terms of flooding is how much falls and how fast, and while it won't be raining all the time, the downpour factor is a concern, said Mike Gorse, meteorologist at the National Weather Service office in Mount Holly.

"It looks like there would be at least some time frame when there would be heavy rain," Gorse said.

It's too early for any flood watches, but the weather service has posted a heads-up statement.
