BOSTON (CBS) – It’s all concerning the tropics proper now, and never a lot of the information is sweet. Fred’s remnants introduced a drenching 2-5” of rain throughout a lot of the realm, significantly north and west of Boston Thursday. Now our consideration turns to Henri, which might ship an already drenching summer time into the notorious class if issues don’t change within the subsequent couple of days.
I feel a have a look at the “wettest summer time on file” leaderboard is instructive at this level. In Worcester, the highest years are 1955, 1938, and 2011 (this summer time is now simply shy of fifth). It is a assortment of notorious tropical years in New England with extraordinarily damaging floods. In 1955, it was twin bother in Connie and Diane. Two programs that arrived inside per week of one another and introduced an amazing quantity of water in a brief period of time. Some cities obtained over 20” of rain. To this present day, these August floods are up there as one of many absolute worst on file in southern New England.
The yr 1938 is thought for a disastrous hurricane that struck in September, however the floods that got here with highly effective winds had been a results of a soaking summer time earlier than the hurricane motored up the shoreline. For the Connecticut River, solely 1936 had a better water degree (extra flood controls had been put in after these very damaging years). And in 2011, a moist summer time stretch was adopted by Tropical Storm Irene. The burst of heavy rainfall worn out roads and bridges throughout western New England and New York, delivering the worst flood in Vermont since 1927.
So that you see a theme. What occurs *earlier than* a storm issues. And we’ve undoubtedly primed our space over the previous two months. Some cities have obtained over 20” of rain throughout that point. Water tables are excessive, rivers are unusually excessive for late August, and we simply had a big rainstorm three days earlier than one other tropical system goes to threaten. Not an excellent mixture.
It is a large concern with Henri, and all of it comes all the way down to what occurs as soon as it will get near southeastern Massachusetts. At this level, there may be growing confidence of a monitor over southern New England on Sunday into Monday.
Both approach, coastal flooding appears to be a threat. The timing is something however optimum, with the moon giving us our highest tides of the month Saturday evening and Sunday evening. It could solely take a foot or two of surge to start out flooding, and a interval of onshore winds at tropical storm power would carry extra surge than that. Particularly if unfold out over a few tide cycles (that left hook/slower monitor).
Backside line is that we regularly deal with winds with tropical programs, and sure that could be a threat as properly. Early estimates name for Henri to be at tropical storm or class 1 hurricane energy on arrival, weakening because it spins close by. However water appears to be our greatest menace for now, each from rain and from the ocean.
So be sure that the sump pumps are working, mills are in good situation, and batteries are able to go. It’s additionally a good suggestion to arrange, even when nature throws us a last-minute curveball that brings a significantly better and lower-impact forecast. Make sure that there’s no particles clogging storm drains or gutters. And we’ll preserve you up to date on any developments because the storm approaches!
