Icy roads were responsible for more than a dozen crashes in Harford County on Saturday, while more freezing rain caused about 10 more accidents Sunday morning.

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.
