Irene looking mean…8/26/11
After reviewing as much data as time would permit, I would like to share with you on what I believe may be the worst storm to hit eastern Massachusetts in 50 years. Some may call it a cop out for waiting until 48 hours before the event to make my final call, but lessons from past experiences held me from making a prediction for such a storm too far in advance. With that being said, if you’ve been following my posts the past several weeks, the talk of a tropical system hitting New England was clearly indicated! -Now on to more serious matters at hand…the storm!
First, I would like to applaud the National Hurricane Center, NOAA, and the National Weather Service for the advancement in technology in trying to forecast the exact path and strength of these often unpredictable and fickle storms. No one has nailed anything yet, but just the fact that they have been able to get the warnings out to the public, speaks volumes as to how far we’ve come over the past 60 years. Just think, back in 1938, there was very little warning for the Great Hurricane of 1938, when 600 people died.
As stated earlier, I believe that Irene will be the worst storm to hit eastern Massachusetts in 50 years. With computer models having first predicted the storm’s eye passing close to the Cape, then shifting it west passing over New York City, they now seem to have come to a compromise somewhere in the middle. This is ultimately the worst track for eastern Massachusetts. Why? Because the most dangerous areas of hurricanes are normally found on the eastern side of the storm. This is where the most damaging winds and coastal flooding take place. In addition, the hurricane will generally remain over open ocean as it makes its way due north up the coast. This will prevent the storm from weakening too much. I am expecting Irene to be a strong category one hurricane when making landfall along the southern New England coast on Sunday evening. At that point, Irene will begin to move inland to the north, then northeast passing through central Mass., then curving northeast through New Hampshire weakening to a tropical storm as it travels further inland.
Now for the forecast. Since the hurricane will affect many of us here in New England, I am going to break down the forecast areas into zones to cover each area. First for the area which I think will be hit hardest by the storm. If you live anywhere from a line from Providence, R.I. to Worcester, Mass. to Nashua N.H. eastward to Portsmouth, N.H. and all points to the south and east, batten down the hatches!!!! Expect conditions to deteriorate rapidly come Sunday afternoon. Watch for heavy rains to develop Saturday night spreading from south to north with increasing southerly winds. Sunday is going to be very stormy! Expect south winds to increase to 40 to 70 m.p.h. with gusts up to 90 m.p.h. during the late afternoon as the hurricane passes to our west. In addition, there will be tropical downpours with 3 to 6″ of rain falling resulting in some flooding. With landfalling hurricanes, there may even be a few week tornadoes touching down to add to the misery. Expect widespread power outages and tree damage. If you live anywhere along the south coast, be prepared to evacuate to higher ground! As the storm moves in, a storm surge of 5 to 8 feet of sea water will flood low lying coastal areas…very dangerous! For people who live in northern and western New England, don’t expect a to get off so easily. No, it won’t be as windy, be you will be dealing with flooding tropical rains to the tune of 6 to 10 inches. Such rainfall falling in a short period like that may produce flash flooding and flooded out roadways. In addition, winds will reach tropical storm force, which range from 40 to 70 m.ph. This is strong enough to break large branches, and cause power outages. People who live along the Maine coast north of Portland will have to be on gaurd for strong southeasterly gusts of up to 80 m.ph. with possible storm surges of up to 5 feet.
Needless to say, if you don’t have to go out from Sunday noontime on, just stay inside with family and friends to ride the storm out! Come Monday morning, the sun will be shining and the clean up will be underway! For what it’s worth, the next two weeks look to bring sunny, warm and drier weather to most of New England. We are going to need it after this weekend!
Well that’s about it for now. In my next blog, I will be reviewing the impacts from the hurricane, and also be giving my Labor Day forecast for you. In the meantime, be prepared for a dangerous period of weather come Sunday into Sunday night, hopefully Irene’s bark is worse than her bite!
