This is an unusual event: when meteorologists say this is a ‘historic’ storm and a combination of events which will accelerate the storm in its last stages into a sharp turn, and drive the central pressure below the 955 MB it was last night. Pressure difference means serious wind, and it is well possible it will come in not as a tropical storm but re-accelerated. Several things are exacerbating this: the energy in the nor’easter, the fact it’s a high tide, and the angle at which it will come in. Exacerbating the potential for damage: trees are still in full leaf, which, sail-like, increases the surface exposed to the wind, ergo the strain on the tree, and falling trees will bring down electric power. This is not only bigger than Irene, it’s got those several complicating factors which put this into territory the scientists say they haven’t seen before. Here’s a technical explanation from two days ago of WHY the cold of northern waters isn’t causing the storm to peter out: note that it’s already sunk below that record pressure cited in the article.Technicals on Sandy
Please, if you’re in that region, err on the side of caution.
