A storm system moving into the Northeast tonight will develop into a powerful ocean storm just south of New England over the course of the day on Friday… and slowly spin east and southeast away from the region over the course of the weekend.
This weather system will bring us a prolonged period of onshore winds and likely a 12 to 18 hour period of strong to damaging wind gusts.
During the height of the storm – which as of right now appears to be late Friday afternoon or early evening into the overnight hours – northeast winds will gusts in excess of 50 mph across the entire Cape, gusts to 60 mph will be common in exposed locations and scattered wind gusts of 70 mph will develop. In fact, some model guidance shows a period of time in which a few locations would be vulnerable to a wind gust of 75 to 80 mph.
Winds will only slowly back off during the morning on Saturday and will very gradually diminish – though remain quite strong with gusts of 40 to 55 mph – through Saturday afternoon and night.
Anticipate areas of tree and limb damage and some pockets of power outages.
