After making landfall in North Carolina this morning, Hurricane Dorian is racing to the northeast. It will pass well off the coast off Nantucket overnight Friday and early Saturday morning, bringing heavy rain and gusty winds to part of New England.
A Tropical Storm Warning is in effect for Cape Cod and the Islands and also some parts of Maine, from Bar Harbor to Eastport. We’re expecting tropical storm gusts in that area overnight and early Saturday morning.
Before that happens, winds will be steady off of the ocean at 10 to 20 mph as clouds thicken up Friday. A few spot showers or downpours will break out during the mid- to late-afternoon south of Boston. As the evening progresses, the rain will fill in as it continues to spread north.
The heaviest rain arrives Friday night and very early Saturday morning, as wind gusts hit 40 to 60 mph in southeastern Massachusetts. Closer to Boston, expect gusts of 35 to 45 mph. A few isolated power outages are possible and ferry cancellations are likely.
Dorian will quickly move into the Canadian Maritimes though, so the rain will wind down early in the day.
In western New England, any rain will likely end between 4 and 6 a.m.
In central Massachusetts and parts of New Hampshire, the steadiest rain will end between 6 and 8 a.m., with just a few spot showers for the rest of the morning.
Around Greater Boston, the worst of the rain will end between 8 and 10 a.m., with spot showers possible through lunchtime.
On the Cape and for parts of the Maine coast, the heaviest rain departs by lunch.
By afternoon, pockets of sun will develop and wind speeds will gradually die down.

Offshore waves will also slowly subside during the afternoon after reaching 10 to 20 feet during the morning.
A spot afternoon shower is actually possible in the mountains of Northern New England, but that’s separate from the storm itself.
When it is all said and done, rainfall will be in the 1 to 3 inch range for much of extreme southeastern Massachusetts, with lower totals as you move north and west.
Sunday looks quite nice, with lots of sun and highs in the 70s in southern New England. We’ll have more clouds, a spot shower, and 60s in northern New England.
Expect 60s under a mostly clear sky for kickoff at Gillette Stadium on Sunday night.
