Hurricane Dorian Update: Tropical Storm Watch Issued for Cape Cod, Nantucket, Martha’s Vineyard

A Tropical Storm Watch has been issued for Cape Cod and the Islands by the National Weather Service, in effect from Friday night through Saturday morning.

Wednesday’s strong to severe thunderstorms came with the leading edge of some nice dry air from Canada.

That dry air is coming in with high pressure today, plenty of sunshine, light wind and high temperature in the upper 60s to mid 70s.

The front is pushing off to the south and attracting Hurricane Dorian up along the coast from South Carolina to North Carolina.

Dorian actually became a little bit more organized Wednesday, and is maintaining strength this morning very close to the South Carolina coastline.

Dorian will continue to crawl agonizingly close along the beach to North Carolina on Friday, and then race south of New England Friday night and early Saturday.

The hurricane will undergo a transition from a pure tropical system to a post tropical system; in other words, Dorian turn from a hurricane into a powerful nor’easter as it goes by New England early Saturday.

For us, that means clouds return Friday with a high temperature close to 70. Rain comes up to the South Coast Friday evening and wind begins to increase. Late at night we may have gale to storm force winds, especially from Rhode Island to Cape Cod, and the coast of Maine, along with wind swept rain especially along Interstate 95, and points south and east to the beaches of southern and eastern New England.

Ocean surf will build to 10 to 15 feet, resulting in possible coastal erosion. The most vulnerable is at high tide near the South Coast before sunrise, and then near the eastern shore early in the afternoon. But most of the wind and wave action should happen when the tide is not high.

Any impact from Dorian will end quickly Saturday afternoon, followed by a mix of sun and clouds and fairly cool air. There is still a weak front around so we will have limited sunshine this weekend with a chance of spot showers both Saturday and Sunday afternoon, but most of the weekend should end up seasonable and mostly dry.
