After a soaking rain and record-setting temperatures yesterday, winter's bite should return today. More than 2 inches of rain fell from Saturday night into yesterday morning at Port Columbus, leading to flood warnings and high water across much of central Ohio.

After a soaking rain and record-setting temperatures yesterday, winter’s bite returned today.

More than 2 inches of rain fell from Saturday night into yesterday morning at Port Columbus, leading to flood warnings and high water across much of central Ohio.

Across the state, numerous low-lying roads and highways were blocked, with flood-prone Findlay among the hardest-hit towns.

According to the Ohio Department of Transportation, the following roads remain closed because of high water:

Franklin County: The ramp from I-270 east to Rt. 23 north (High Street). The detour is I-270 east to Alum Creek Drive to I-270 west to Rt. 23 north. Delaware County: Rt. 257 bewteen Rts. 37 and 47. Union County: Rt. 37 between Richwood and Rt. 739. Pickaway County: Rt. 762 between Rts. 23 and 104. Marion County: Rt. 203 between Rts. 4 and 47; Rt. 95 betweeen Rts. 203 and 95; Rt. 37 between Rts. 309 and 739.

Numerous low-lying roads near overflowing creeks and rivers also are closed this morning throughout central Ohio.

Major flooding is expected in Prospect in Marion County where the Scioto River was at 12 feet 9 inches this morning, nearly 4 feet above flood stage. It is expected to reach 15 feet 1 inch by Tuesday morning, according to the National Weather Service.

Saturday saw a record-breaking high temperature of around 69 degrees shortly before midnight in Columbus, weather service meteorologist Andy Latto said. The record was 64 in 1967.

Yesterday’s high of 68 degrees also set a record, breaking the Dec. 22 record of 62 degrees set in 1941, according to the National Weather Service.

But those springlike thermometer readings are history. The temperature was 34 degrees by this morning, and the high is expected to be in the mid-20s by Christmas Eve.

"It’s going to be cold,” Latto said. “That’ll be the story.”

The weekend storm hit highways hardest in Sandusky, Seneca and Wood counties in northwestern Ohio.

In Findlay, about 100 miles northwest of Columbus, the Blanchard River has risen 12 feet since Friday to major flood-stage levels.

By 7 a.m. this morning, the river was a little over 15 feet, cutting the city in two. The water level is expected to begin falling after today.

The river has flooded four times since 2007.

Today in the Columbus area, flood warnings remain in effect in much of Delaware and Union counties, along Big Darby Creek in Franklin and Madison counties, along the Scioto River in Pickaway County and near Buckeye Lake in Licking and Fairfield counties. Roads also are closed by high water in Knox, Morrow and Wyandot counties.

Emergency-management officials and firefighters were going door to door in parts of Marion County yesterday, advising two dozen households in and near the village of LaRue that it might be time to leave. The American Red Cross opened a shelter in LaRue at Dry Lane Construction Co., 376 Dry Lane Rd. S., for Marion County residents.

Several senior citizens were evacuated just before 9 a.m. from the Kiwanis Retirement Village, said Marion County EMA director Harry Burdick.

“I’m seeing water that I’ve never seen before,” he said. The flooding affected between 50 and 60 houses, he said. Some people spent the night at a shelter opened by the Red Cross.

The Scioto River at Larue has crested, according to the weather service, reaching 13 1/2 feet, or about 2 1/2 feet over flood stage, and should be below flood level by Thursday.

In Delaware County, two houses were flooded by the Scioto River along Riverside Drive and two houses were flooded along Rt. 257, EMA officials said.

The storm caused damage in southern Ohio as well, knocking over trees and power lines near Portsmouth. American Electric Power reported outages for 2,000 customers in Scioto County and 1,300 in Adams County around 1 a.m. yesterday, but most of those customers had service again by yesterday afternoon.
