Although temperatures are slated to warm up for the weekend, the last bit of cold weather played havoc with schedules and driving in Harford County Friday morning.
And as it warmed up at mid-day, the county was placed under a flood watch for most of Saturday.
The National Weather Service issued a flood watch for the Harford County area around 2:20 p.m., said Bob Thomas, coordinator of community outreach and public information of the Harford County Department of Emergency Services.
Flood watches indicate the possibility of floods, specifically in low lying areas, based on the amount of rain, said Thomas.
"It doesn't mean that is it absolutely going to happen," Thomas said. "it is telling us that there is a possibility and we should be on alert."
According to the National Weather Service website weather.gov, the flood watch covers the period from 9 a.m. Saturday to 12 a.m. Saturday.
Aberdeen Proving Ground temperatures remained near freezing throughout the day, according to the NWS, which monitors the weather for Harford at APG.
At 5:58 a.m., the NWS reported the temperature at 34 degrees with a slight drizzle. As the morning went on, light freezing rain, fog and midst were reported at APG around 7:58 a.m. with the temperature at 32 degrees.
The temperature rose to 36 degrees at 1:50 p.m. with light drizzle, fog and midst and was still at 36 at 3 p.m., according to the NWS website.
The freezing rain early Friday made streets slick and caused both local schools and the county government to open late.
Harford County Public Schools opened two hours late on Friday with no morning pre-K or preschool services, said Teri Kranefeld, manager of communications for HCPS.
County government offices opened at 10 a.m. on Friday with liberal leave for county employees, said Bob Thomas, coordinator of community outreach and public information for the Harford County Department of Emergency Services.
Several accidents were reported on county roads Friday morning.
"For those having to travel the roadways this morning, freezing rain is coming down, use caution and give yourself some extra travel time this morning," urged the Harford County Fire and EMS blog on Facebook.
A vehicle flipped over a Route 136 and Tucker Road in Darlington around 6:13 a.m., according to Rich Gardiner, spokesperson for Harford County Fire and EMS.
One person was taken to regional trauma by ambulance, Gardiner said.
There was a single vehicle accident at Route 161 and Glenville Road in Darlington around 7:58 a.m.. One person was taken by ambulance to a local hospital, Gardiner said.
Side streets and parking areas in the Bel Air area still had thin coats of ice around 10 a.m., even though it had been raining fairly steadily for several hours and temperatures had begun rising.
With Friday's delayed opening, Harford County Public Schools either have either opened late or were closed because of poor road conditions and freezing four of five days this week. Schools two hours late on Monday because of foggy conditions, were closed because of the record low temperatures on Tuesday and then opened two hours late on Wednesday because of icy roads. Schools were also closed last Friday because of snow.
In addition, several individual schools have been closed in recent days because of mechanical failures at the schools.
Abingdon Elementary School closed early on Monday after officials discovered there was no heat in the building. Joppatowne High School and Fallston Middle School were closed on Wednesday because to mechanical failures.
