Much of southern and coastal Maine is under a winter storm warning this morning.

"Adding up what fell Thursday night, plus what's coming on Friday, storm totals for areas closer to the coast will end up around five to nine inches," Senior Weather Producer Justin Gehrts said.

The National Weather Service in Gray urges caution for those who have to venture out as roads will be slick.

The NWS predicts a dry weekend before another storm arrives Sunday night into Monday, bringing more snow, high winds and coastal flooding.

As of 8:30 a.m.,Central Maine Power reported nearly 4,000 customers were without power, the vast majority of those in York County.

Just before noontime, that number had dropped to 634 total, with the majority of those still in York County. Most of the outages were reported in Acton, Kennebunkport and South Berwick.

Farther north, Versant reported no major outages, according to its website.

School districts statewide canceled classes for the day Friday, including Portland, Bangor, Lewiston, Regional School Unit 14 (Windham), RSU 21 (Kennebunk area) and RSU 1 (Bath area).

Some larger cities, such as Lewiston and Bangor, have parking bans in effect through Friday morhning.

In Portland, the city has not issued a ban but asked residents for "voluntery compliance" in using snow ban lots and other off street parking.

Portland City Hall will have a delayed opening at 10 a.m. Some towns, such as Gray, have advised that municipal offices will also close due to the snow.
