Tropical Storm Isaias is expected to track up the Hudson Valley Tuesday evening and overnight, bringing some rain and occasionally gusty winds to Cape Cod. Most of the storm's effects were expected to be felt well to our west; read the latest updates here.
A tornado watch was issued for Southern New England, including the Cape, through 9 p.m. Tornadoes and waterspouts are common when tropical storms make landfall and weaken.
Isaias could still produce scattered power outages on Cape Cod, officials warn. While the winds will be similar to a typical fall coastal storm, trees are still covered in leaves and are more susceptible to wind damage.
At midday Tuesday, the Barnstable County Regional Emergency Planning Committee reported that peak winds are expected at around 9 p.m., with sustained winds of 50 to 55 mph gusting to 65mph. Most of the rain will be on the Upper Cape, with possible thunderstorms and a slight chance of a tornado. Storm surge from Isaias will be minimal, but up to two feet of surge could occur on Nantucket Sound-facing beaches.
"Citizens who are camping in tents should consider seeking other accommodations today and this evening," the REPC advisory reads. "Businesses and organizations using tents for outside seating and services should make sure all structures are secure."
The storm will make its way out of Cape Cod region by early morning on Wednesday, possibly leaving scattered power outages and communication outages in its wake.
