GRAY — The National Weather Service Friday has issued a winter storm watch for Sunday, as a coastal storm could bring 6 to 10 inches of snow.

A fast moving low pressure system is expected to move up the northeast coast and across Cape Code Sunday night, spreading snow into Maine and New Hampshire Sunday evening into early Monday morning, Dec. 30.

This latest storm is likely to produce a band of heavy snowfall, although some of the precipitation may fall as rain near the immediate coast of Maine and across southern New Hampshire. Inland areas of central New Hampshire and western Maine, along with the Midcoast are expected to be most impact by heavy snowfall, according to the NWS in Gray.

The winter storm watch is in effect from Sunday afternoon through Monday morning. Heavy snow will cause travel difficulties, and areas that still have ice on trees from the ice storm earlier in the week may be more susceptible to accumulations, causing additional broken limbs, downed wires and power outages.

Winds are expected to be 10 to 15 mph with gusts up to 20 mph, and temperatures will be in the 20s.

Friday afternoon: Sunny, with a high near 33 F. West wind around 10 mph.
