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

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.

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.
