The National Weather Service has issued a flood watch for York County from early Thursday morning until Friday morning.

Rainfall began Wednesday afternoon, and the continuous showers are expected to produce totals of 3 to 5 inches or higher throughout the area. Barry Lambert, senior forecaster for the National Weather Service in State College, said the flood watch is expected to run from around 2 a.m. Thursday until Friday morning.

“What would really cause flooding issues to arise is if we get a lot of showers, heavy showers and even some thunderstorms, repeating over the same area,” Lambert said.

The potential for flooding is highest near small streams, creeks, areas with poor drainage and low-lying areas, according to the weather service. The threat for flooding in mainstream rivers is low because of extremely dry conditions during the past few weeks, but the waterways will be monitored during the next 24 to 36 hours.

“Three to 4 inches over the period of 48 hours, with the dry conditions … it’s probably not going to cause a lot of problems,” Lambert said.

Residents are advised to monitor forecasts and be alert for potential flooding, the weather service advised. Lambert advised people to keep an eye on the forecast to see if rain continuously hits the same area.

Additionally, he urged people to not drive in standing water.

“You don’t need much water to start moving a vehicle,” he said.

Thursday's forecast calls for at least an 80 percent chance of rain throughout the day, with heavy rain expected during the morning. The high is expected to be in the upper 60s, with the low around 62, according to the weather service.
