Cummins said BGE crews had to remove the downed lines and pole, and then repair the damage.

State Highway Administration crews then had to treat the road.

Shortly after 11 a.m. Friday, Thomas said county roads were passable, but drifting snow was a concern.

The Harford County Department of Emergency Services 911 Center reported 23 accidents occurred throughout the county from 4 p.m. Thursday until 4 a.m. Friday. Four of the 23 accidents resulted in personal injuries.

There was a collision between a tanker truck and an SUV on Route 152 at the I-95 exit ramp shortly after 9 a.m. Friday that had traffic backed up on Route 152 and forced detours for several hours. Minor injuries were reported by the Joppa-Magnolia Volunteer Fire Company which responded.

According to Thomas. the Harford County Emergency Operations Center north of Bel Air activated to Level 1 staffing at 5 a.m. Friday, with Harford County Emergency Manager Rick Ayers and emergency management staff to monitor the storm and conditions throughout the county.

Despite winds gusting to 35 to 40 miles and early morning temperatures in the teens, power outages were minimal. As of 7 a.m., there were less than 15 customers without power in the county, according to the county news release.

In an early morning Facebook post, Ayers had expressed concern about drifting snow on roads and widespread power outages. Those concerns had lessened by mid-morning, but emergency officials continued to advise people to stay off the roads if possible.

"Today one of our concerns is the subfreezing temperatures and wind chill," Ayers said. "Those who venture outdoors should dress for blizzard like conditions and stay hydrated."

"Because of the icy conditions on our roads, those who do not have to travel should wait until conditions improve," Ayers added.

Thomas said Harford County Executive David R. Craig decided to close government offices because of the severe weather and hazardous driving conditions.

The county's emergency services department reported 14 emergency calls in response to road conditions between 3 and 7:30 p.m. on Saturday, according to a press release.

Only two accidents included injuries and one accident involved a rescue, according to the release.

On Sunday morning, the Harford County Sheriff's Office reported two or three accidents caused by the ice.

There did not seem to be any injuries from them, spokesman Edward Hopkins said.

The emergency services department reported 10 accidents, causing only property damage, from 7 a.m. to noon, spokesman Bob Thomas said.

The National Weather Service issued a freezing rain advisory for Harford County from 6 a.m. to noon Sunday, but then extended it until 3 p.m.

The temperatures were expected to rise Sunday afternoon and into Monday.

A "polar vortex" is set to move in from the Midwest on Tuesday, causing dramatically low temperatures with a wind chill possible of up to 10 degrees below zero.

"As roads refreeze motorists must reduce speed, keep a safe distance from vehicles in front of them and exercise caution," emergency operations spokesman Rick Ayers said Sunday.
