What scares me is that a lot of people will not take this one seriously. Think of this as a nor'easter with the engine of a category 3 hurricane. The models show that the wave and surge threat from this will have the equivalent effect of a category 4 hurricane on the coastline (or a rank of 5.2 on a scale that maxes out at 6). The low pressure at landfall will be 950 millibars (mb )or lower. I lived where the eye of Hurricane Juan slammed Nova Scotia a few years ago, and it's low pressure was 974mb. The lower the pressure, the higher the wind and heavier the rain. The storm surge from this will be huge, and occurring during monthly high-tide. Now for the wind. Unlike a hurricane, the wind-field from this will be enormous geographically, with sustained winds at or near hurricane or tropical storm force. As this is a slow mover, also unlike a hurricane, these winds and larger gusts will be sustained for over 24-36 hours. Trees still have leaves on them, and the ground will be saturated. Many trees will topple, and current models expect over 10 million people to be without power for several days.
Anybody who lives in the warning areas and does not take this storm seriously is a moron.
