With a moderate but steady rainfall expected to arrive beginning Wednesday evening and lasting into Thursday night, the National Weather Service at Wilmington has issued a flood watch effective from Wednesday evening through Friday morning.
The watch area includes Scioto, Pike and Adams counties.
According to the weather service, showers will develop along a cold front today. This front will lay out along the Ohio and West Virginia border Wednesday night and Thursday. After an initial round of rain today, steady and moderate rainfall is expected overnight and Thursday northwest of this boundary, roughly following the Interstate 71 corridor. More rain will fall overnight Thursday, associated with an elevated low-pressure trough.
With several inches of rain possible, some flooding may occur.
People in the watch area, especially those living in areas prone to flooding, should be prepared to act should flooding develop. Monitor the latest forecasts and be alert for possible flood warnings.
