What to Know About the Multi-Day Nor'easter Approaching New England This Weekend

The still strengthening storm is expected to bring heavy winds and rain, causing possible flooding and power outages



    Strong Winds, Torrential Rain Approaching New England

    Wednesday: Showers expand, ramp up to rain. Becoming windy. Highs in the 50s. Overnight Wednesday Night: Windswept, torrential rain. Lows around 50. Thursday: Windswept, heavy rain. Some power outages with northeast gusts to 45 mph, higher Cape. Highs in the 50s. (Published Wednesday, Oct. 9, 2019)

    The much anticipated nor’easter has developed over the waters south of New England and will continue strengthening over the next 24 hours.

    This storm center is fueled by all of the classic ingredients for storm development: atmospheric energy provided by the jet stream winds aloft, cool air surging south from Canada and warmth over the Gulf Stream waters of the western Atlantic.

    When will the nor'easter hit New England?

    The clash of temperature, combined with the available energy, is allowing the developing storm center to our south to gain footing, and we’ve seen both the cloud structure and wind pattern becoming more organized through the day on Thursday.

    The cool air pushing south out of Canada means business, however, and is also dry by nature, pushing back effectively against the southern surge of moisture and making any northward progress of rain very slow Thursday.

    How will it impact Columbus Day weekend leaf-peeping/tourism?

    Surprisingly, it looks like the key leaf-peeping areas may dodge the bulk of this storm.

    In fact, while our First Alert Weather Team expects showers to trudge north to the New Hampshire border by Thursday evening, anywhere farther north than Manchester, New Hampshire, will stay much drier – and for some, entirely dry – over the coming days.

    While a dry forecast for the North Country bodes wonderfully for the all-important foliage-oriented tourism weekend of Columbus Day, with only a gusty breeze to dislodge some of the peak color foliage but no leaf-stripping rain, it’s a different story for southern New England.

    You’ve heard the term, but did you know that a nor’easter just refers to the direction of the wind?

    Will the storm cause damage and power outages?

    After a slow ramp-up in rain and wind Wednesday, late Wednesday evening through the overnight expect northeast gusts to exceed 40 mph on Cape Cod, and isolated power outages are possible by daybreak. The impactful wind – and heaviest rain – are expected throughout the day Thursday into Friday.

    Thursday’s wind gusts should exceed 60 mph on the Outer Cape and exceed 50 mph along the eastern Massachusetts coast, with 40 mph gusts reaching very far inland across southern New England, all contributing to scattered power outages.

    What about flooding?

    Additionally, heavy rain to the tune of two to four inches with localized amounts over half a foot possible not only will cause pockets of flooding, particularly when combined with falling leaves clogging storm drains, but also will soften the ground enough so uprooted trees are a possibility in strong wind gusts.

    While the most intense rain and wind is expected Thursday, Friday surely will deliver a wind-whipped rain again, and some new power outages will be possible.

    At the coast, the persistent onshore wind will build seas to 20 feet, meaning beach erosion will be a concern and coastal flooding is a possibility at the roughly midday high tide Thursday, Friday and perhaps Saturday.

    While the storm will be much weaker Saturday, the onshore wind will continue and likely will deliver areas of steady drizzle and light rain.
