BOSTON (AP) — Commuters heading back to work in Massachusetts for the first time since the blizzard are being urged to use caution and leave extra time.

Many secondary roads still have a thick coating of snow, and high snow banks that block sight lines at intersections and near highway ramps make turning and merging hazardous.

In many communities, snow removal crews were out early, making driving even more tricky.

State officials are urging commuters to take public transportation when possible.

The MBTA says regularly scheduled service will resume Monday, but warns that customers should expect significant delays.

Schools in Boston and many other communities remain closed, which could ease some congestion.

Nearly 113,000 Massachusetts electric customers remained without power Monday morning, mostly on the South Shore and Cape Cod.
