FRANKLIN COUNTY (April 14) — Watch out tonight, and consider staying inside if you can.
The entire county — and all of South-Central Pennsylvania — is under a tornado watch as well as a flash flood watch.
Locally, the tornado watch is in effect until 3 a.m. tomorrow. The flood watch will remain in effect until 6 a.m., according to the National Weather Service.
Severe thunderstorms with damaging winds of 60 miles an hour or greater are possible, forecasters said.
Tornadoes form in unusually violent thunderstorms when there is sufficient instability and wind shear present in the lower atmosphere.
Those two conditions will be present most of the night, according to NOAA forecasters.
Heavy rain from tonight’s thunderstorms, coupled with rain a good part of the day today, may also lead to regional flooding, something that is not uncommon at this time of year in Franklin County.
While tornadoes are not a common, generally thought to hit hardest in the US’s “tornado alley’ in the central Midwest, they aren’t unheard of here in Franklin County.
Make sure you have a way to receive warnings tonight, Franklin County Emergency Services advises.
NOAA Weather Radio All Hazards (NWR) is a nationwide network of radio stations broadcasting continuous weather information directly from the nearest National Weather Service office.
Locally they include WXM42 out of Hagerstown and WWG52 from Huntington.
