DOVER, Del. (AP) — Utility crews were working to restore power to more than 25,000 residents of northern Delaware after a winter storm pelted the region with rain, sleet and snow.

Schools and government offices in New Castle County were closed Tuesday, and state lawmakers canceled a scheduled legislative session.

With the storm approaching, Gov. John Carney issued a driving warning Monday urging New Castle County residents to stay off the roads. Carney's office said the warning would be lifted at noon Tuesday but that motorists should still exercise caution.

The city of Newark was closed, and morning classes at the University of Delaware were canceled, with the campus to open at noon.

Delmarva Power reported more than 27,000 customers without power Tuesday morning in New Castle County, and another 13,000 in neighboring Cecil County, Maryland.

Meanwhile, a flood advisory was in effect until noon Tuesday for much of Delaware and northern counties on Maryland's Eastern Shore.

Heavy winds continued to rake the Delmarva peninsula late Tuesday, with sustained winds of more than 20 mph and gusts up to about 50 mph.
