High winds forecast for Monday storm

Winds could gust to 70 mph Down-Cape

Statement from the National Weather Service in Boston concerning Monday's forecast storm:

A significant coastal storm is on the way from late Sunday night into early Tuesday. The brunt of the storm will come late Monday afternoon and Monday night. It will be multi-faceted. But the most dangerous part of the storm will be the winds and rough seas.

A High Wind Warning is in effect for Cape Cod and the Islands already. We are forecasting gusts of 60-70 mph, highest on Nantucket and outer Cape Cod, late Monday afternoon and Monday evening. Storm Warnings are in effect for the adjacent coastal waters, where gusts to near hurricane force (60 knots) are expected. Seas will be building rapidly up to 20-23 feet just off the coast. Very dangerous situation for mariners. We are expecting some power outages and tree damage in the Warning area. Wind gusts of 40-50 mph will be common across the rest of RI and eastern MA.

Heavy rain...of 2 to 3 inches...is expected in eastern MA and RI, which will cause urban and poor drainage flooding. However, if we get 3 inches or more, there is a possibility of some isolated small stream flooding, so a Flood Watch has also been issued for those areas.

Farther to the northwest, a wintry mix of snow, sleet, freezing rain, and eventually rain is expected. Right now we are thinking Advisory-level snow (2 to 5 inches) in the slopes of the Berkshires and northern Worcester County hills. Perhaps up to 6 inches in northwest Franklin County, MA. A lot of sleet is possible in those areas. Also, a tenth or two of ice accretion is possible in the same areas. None of these, individually, add up to Winter Storm Warning criteria, but it will be messy. A very slight change in the temperature in the lower atmosphere could affect the snow/sleet totals - either less or more. Stay tuned.

High Wind Warning 10:00 a.m. Sunday 01/22/2017
