The National Weather Service issued a number of warnings, watches, and advisories for Warren County on Thursday.

A flash flood watch ran from early afternoon through early Friday morning.

Sudden, heavy rains added to already wet conditions to bring the water level up throughout the county. Yards were deluged, homeowners had to pump out basements, and roadways were flooded.

Stretches of Jackson Run Road in Sugar Grove Township and Davey Hill Road in Pittsfield Township were closed, according to PennDOT.

A flooded roadway can be dangerous.

When faced with water, especially moving water, on a road, motorists are advised to be cautious.

Moving water can undermine a road. That change may be invisible from a motorist’s point of view.

According to the NWS, six inches of water is enough that most drivers will lose control of their vehicles.

And, the buoyant force of 18 to 24 inches of moving water is enough to wash most vehicles off a road.

The NWS reminder in cases of flooded roadways — “Turn around, don’t drown”

According to the NWS, there are about 100 drowning deaths in floods each year and mor than half of those are in vehicles that the driver attempted to more through the flooded area.

Whether told by a police or fire officer, faced with a sign, or simply looking at a flooded road, drivers might not want to simply go back and look for the nearest road that parallels the desired route, according to Public Safety Director Ken McCorrison. Conditions are likely to be similar and the dangers on a smaller road could be even greater.
