Heavy rains kept local emergency crews busy with rescues and evacuations Thursday, and meteorologists warned residents to prepare for another couple inches of precipitation over the weekend.

At least two school districts announced plans to close early Friday as tributaries were being overwhelmed and basements were taking on water around York County.

York County Control was continuing to receive reports of standing water on roads Friday at press time, with several roads having been closed for flooding, said county spokesman Carl Lindquist.

Motorists were trying to drive through standing water, and there had been at least three water rescues since the start of rain Thursday, he said Friday morning.

People were assisted in West Manchester Township, at Indian Rock Dam Road and Hokes Mill Road, and in Fairview Township at Old Trail Road North at Old Mill Inn Road.

Evacuations: Rescue crews at a third site, on Pine Road in Dover Township, used a boat to remove residents from an oft-flooded mobile home park.

In Hellam Township, about 10 residents from Prince Mobile Home Park were evacuated.

Chief Kent Rudisill of Hellam Fire Co. said the evacuation started at 8 p.m. Thursday at the mobile home park along Freysville Road.

Residents went to the higher ground of the mobile home manager's office, Rudisill said. The York-Adams Chapter of the American Red Cross was called to the scene to assist residents.

Rudisill said he didn't know how long the evacuation would last, as it depended on how long it continued raining.

Forecast: It could be a while.

The National Weather Service had extended the flood warning from midnight to 4 p.m. Friday for York, Adams and Lancaster counties. The weather service also issued a flood watch until 8 p.m. Friday.

Rain, heavy at times, will continue through the weekend, according to John LaCorte, a meteorologist with the National Weather Service in State College.

More than five inches of rain had been reported for York County between Thursday morning and 8 a.m. Friday morning, he said.

LaCorte said a low along the Atlantic Coast fed the storm moisture, and the storm has essentially stalled over the region, creeping west instead of moving with the normal jet stream.

"Anytime we get this kind of rain it's not normal," he said. "There's a pool in the atmosphere and it's just going to spin itself out ... moving very slowly."

LaCorte warned that motorists should not attempt to drive through areas where water covers the roads and should watch out for flash floods while traveling at night.

Siding with safety, Northeastern and Southern school districts were dismissing students early.

The weather service also advised that people living in areas prone to flooding should have safety plans in place in case a flood develops.

Rain drops out of the forecast on Monday, which is expected to be mostly sunny with high temperatures in the upper 60s.
