Mainers woke to a mix of snow and ice Wednesday morning, which has caused some schools to cancel or postpone classes but has led to remarkably few car crashes in southern Maine.

However, the Maine Turnpike Authority did report two early-morning crashes at mile 77 southbound in Auburn, temporarily blocking the left lane.

The speed limits on the Maine Turnpike and Interstate 295 were lowered through much of the morning because of slippery roads.

Emergency dispatchers with Maine State Police, Cumberland County Regional Communications Center and the Sanford Regional Communications Center in York County reported few crashes and none serious.

The National Weather Service in Gray said it expected up to an inch of snow and one-tenth of an inch of ice by Wednesday morning in southern and coastal Maine, prompting a winter weather advisory, but later in the morning it changed to rain. Skies are expected to clear Wednesday night.

Temperatures Wednesday are expected to be in the upper 20s to low 30s, according to the National Weather Service.

Among the cancellations and delays: Portland schools are closed, Brunswick schools delayed the start of classes for two hours and the University of Southern Maine started classes at 10 a.m.
