Warren County flood warning

Tropical Storm Gordon is teaming up with a frontal boundary to put Warren County under a flood watch.

According to the National Weather Service office in State College, “a long duration, heavy rain event” is putting the county in a flood watch through Monday evening.

“We’re expecting an additional one to three inches (of rain), maybe more locally,” Meteorologist Michael Colbert said. “There’s a big, old frontal boundary that’s been hung up over us.”

“We’ve had plenty of rain falling over a very large area,” Colbert said. “There’s cool, dry air to our north, hot, humid air to the south. Along those boundaries there is commonly precipitation.”

The fronts are the main source of the “substantial rain” in the area, he said, but the remnants of Gordon “is also contributing to the rainfall now.”

That rain could cause flooding of low-lying areas and along rivers and creeks, he said.

The good news is that the county did not receive significant precipitation on Saturday.

“It does help out that you didn’t get much yesterday,” Colbert said. “That cut down on your storm totals. Points farther south weren’t as lucky.”

The watch remains in effect through 8 p.m.

Forest and Venango counties were among those under a flood advisory through Monday morning.

Parts of Clarion and Jefferson counties form the northern border of a large swath of the state under a flood warning through Monday morning.
