Flash Flood Watch into Friday

National Weather Service has issued a flash flood watch in Central Pennsylvania into Friday due to expected periods of heavy rain “to excessive rain.”

“An extensive plume of tropical moisture will combine with a warm front over the region to focus several rounds of showers and thunderstorms today into early Friday. Some of the thunderstorms could train northeast over the same areas, elevating the threat for Flash Flooding,” the NWS at State College warns.

The watch is for all of Central Pennsylvania through Friday morning.

Here’s more of what forecasters predict: “Several rounds of moderate to heavy showers, and the potential for localized training of thunderstorms across the same locations, could lead to excessive rainfall rates of 1 to 2 inches in less than an hour, and bring the threat of flash flooding.”

Be aware, forecasters said, that “flood prone roads adjacent to streams could be eroded and washed out by high, fast-moving water. If you encounter water over the roads turn around and seek and alternate route. Washed out roads and the depth of water over the roads is especially difficult to discern at night.”
