A winter storm that’s expected to drop up to 10 inches of snow across much of Maine is prompting state officials to warn drivers to stay off the roads.

Maine State Police tweeted Monday that “troopers are going from call to call responding to slide offs” on I-95.

“Please stay home if you can,” they tweeted. “If you have to drive, drive slow and give crews a safe distance to work.”

By mid-afternoon, police had responded to 64 crashes and slide-offs since the storm started. Most were caused by drivers going too fast, police said.

The storm has also caused thousands of power outages in York County, according to Central Maine Power.

As of 2:45 p.m. Monday, CMP reported 27,100 customers without power in York County, 105 in Cumberland County and 304 in Lincoln County.

CMP spokesman Jon Breed said most of the York and Cumberland County outages were caused by "snow covered limbs and fallen trees."

Versant Power, which serves northern and eastern Maine, reported one outage.

The storm, which is predicted to continue through much of Monday, caused widespread school and government office closures and another round of parking bans.

The National Weather Service in Gray is warning that northwest winds will increase this afternoon, which could lead to more power outages.

Monday's storm follows one on Friday that brought the season’s first measurable snowfall to much of the state.

Prior to Monday’s storm, Central Maine Power warned that wet snow and strong wind gusts, particularly near the coast, could bring power outages.

They echoed the warnings of police to slow down on the roads, noting that about one-quarter of the outages on Friday were “the result of car accidents causing damage to utility poles.”
