The National Weather Service's flood watch remains in effect for York County and surrounding areas until 7 p.m. Sunday.
The warmer temperatures on Saturday led to significant melting and ice break-up on waterways in South Central Pennsylvania, said Craig Evanego, a meteorologist with the weather service in State College.
Although some might find it unusual to have a flood watch with no rain in Sunday's forecast, the main concern is ice jams, which block waterways and cause flooding, he said.
But no flooding has been reported in York so far, Evanego said.
"I don't think anyone has seen anything major," he said.
Sunday's forecast calls for sunny skies with a high of 46, followed by an overnight low of 28.
The next precipitation in the forecast is Monday night, when there's a 60 percent chance of rain. Tuesday will see a 50 percent chance of rain during the day and a slight chance of snow showers overnight.
