Hurricane Irene: What Are The Primary Threats To Southern New England?

By Terry Eliasen, Meteorologist, WBZ-TV Exec. Weather Producer

BOSTON (CBS) – As Category 3 Hurricane Irene continues to churn through the Bahamas, folks along the East Coast from the Carolinas to New England are keeping a close eye on the projected path and forecasted strength.

Weather models overnight and this morning made a pronounced shift to the west. Most models yesterday had the path over eastern Massachusetts, now this morning, many have shifted west towards Long Island and Connecticut.

This is a very significant change for many reasons.

First, the core of the hurricane force winds typically only extend out some 50-to-100 miles from the center of the storm.

WBZ-TV Meteorologist Barry Burbank looks at recent New England Hurricanes:

So, the farther away the center passes, the less chance that we would experience hurricane force winds.

Also the heaviest rainfall is always to the west of the path of the hurricane, therefore with a track well to our west we could also miss out on the heaviest rain amounts.

We have to stress that the storm is still three days away and the track will continue to shift.

The eye is continually reforming, causing slight shifts in track and also Irene’s interaction with the Jet Stream over the U.S. will be vital.


Storm Surge and Coastal Flooding

This is likely the biggest threat that we will face from this storm with the most potential damage. The storm surge could be as large as 10-to-15 feet along the South Coast and seas could swell up to 30 feet just offshore.

Tides are astronomically high on Sunday due to a new moon.

The high tide we are most concerned with is Sunday night’s which occurs around 8 p.m. on the South Coast and just before midnight in the Boston area.

With the right storm track there could be significant funneling in Buzzards Bay and Narragansett Bay, leading to destructive flooding.


Obviously the winds are the first thing people think of when a hurricane is headed their way and the track of the storm will ultimately determine the strength and location of the wind.

The strongest and most damaging winds always occur on the east side of the hurricane. Therefore those located in the closest vicinity of the storms center and to the right would experience the worst of the wind.

Currently with a track farther west, many folks in eastern Massachusetts could be in line for significant wind gusts, and those closer to the track in central Massachusetts perhaps even stronger winds.

If Irene maintains hurricane strength in New England, winds would likely be sustained at 70 mph or greater along the South Coast and could gust to near 100 mph.

The winds would likely diminish somewhat the farther inland you go, but 50 mph+ would still be easily attainable.


The heaviest rainfall is typically to the west of the storm track.

Given the current forecast path, this would leave most of us in southern New England out of the heaviest rain totals.

They would be confined to western Massachusetts and New York State where 5-to-10 inches+ could fall causing significant flooding.

There would be bands of rain in eastern and central Mass. and New Hampshire arriving as soon as Saturday afternoon

The heaviest rain would occur for about a 6-to-10 hour period as Irene approaches and passes by.

Residents east of the track could still receive 2-to-5 inches +, nothing to sneeze at.


We will continue to monitor any trends today and changes in the forecast, but we urge everyone to begin to prepare now for the worst case scenario.

This storm still has the potential to deliver a very significant blow to Southern New England not too dissimilar from Hurricane Bob in 1991 or Hurricane Gloria in 1985.

    Translated, this article means we have whipped up a hurrican is coming, the world is ending frenzy – wait -never mind.

    Sounds like Earl all over again. Whe a REAL storm comes and everybody ignores it let’s beat the boy who cried wolf with an iPad until both are left in a heap!

    • Aaron Root

      Apparently you dont know the difference between east and west. If you did you would know his sounds nothing like Earl.

  • Becky Tornblom

    I do wish forecasts would be more considerate of Central and Western Massachusetts – I get the feeling that the discussion is flavored by a tendency to minimize any track which takes it away from greater Boston. This makes many of us in Central Mass feel a bit, shall we say, diminished…

    • jn

      Well said Becky. I was thinking exactly that, all they care about here are those in southern and eastern mass, don’t worry about the rest of us out in the western/central part of the state!

    @ TODD: When a hurricane approached New England, does the wind field usually expand?

  • qwerty

    Another boring non-event hyped beyond all imagination by the local media. I expect the thunderstorms this afternoon to be worse.

    I don’t know about the rest of you, but I hope it does turn out to be a non event. If the forecasters didn’t warn everyone and the worst happened, everyone would complain about that too. So, be prepared just in case, and don’t complain if you get hit while you’re not looking.

    • Italo

      I’m watching The Weather Channel now (with mute button always at the ready, b/c of their constant ad breaks about every 34 seconds, as usual), and I’m getting the sense that an epic Armageddon event is about to start its way up the eastern coast. I have a feeling that this storm will continue to move westward, so much so that it will make shore inland off New Jersey or Pennsylvania, being much like just a big summer nor’easter for our area.

  • Ellen

    Yes indeed be prepared, but don’t overreact either. Have faith in God, buy not only food, milk, batteries and so forth but how about red wine, and cupcakes to go with it. Enjoy, relax and celebrate life.

    • cellbody

      Sounds like you’ve got it easy.

    • Willow

      Amen to that, Ellen. :)

    • Aaron Root

      Good idea Ellen. With all the forecasted power outages milk will be the best thing to have.

  • Mrs. anonymous

    Wbz – “50mph winds”, NECN – “110mph winds/gusts up to 140mph”, TWC – “65 mph winds”. WHO & WHAT are we to believe? I just wish all the weathermen would just PLEASE get on the same page!
