Cat 3

Expected to be Cat 4 by tonight:

Irene is forecast to move to the northwest, passing over all of the Bahamas by Thursday evening, then curving to the north. Irene then makes landfall in the US near or at the Outer Banks Saturday afternoon, then traveling along the mid-Atlantic coastline of the US. After Saturday, Irene may pose a threat to Long Island and the New England coastline. However, NHC is quick to remind us that the average forecast error for day 4 is 200 miles, so don’t stop your hurricane preparations if you aren’t in the immediate area of landfall. It is also important to note that the windfield of Irene is expected to be large, affecting areas distant from the immediate track of Irene’s center. Tropical storm forces winds are expected to be found out to at least 150 miles away from Irene’s center on Friday afternoon.

One thought on “Cat 3

  1. As a former resident of my beloved New Orleans, the thing that strikes me about the predicted track is that the entire coast is on the wet side of the hurricane. (It circulates counterclockwise, so on a track moving northward while east of the coast, all the moisture it picks up over the ocean gets dumped on land.) That means potential flooding, whether the high winds at the center are over land or out to sea.

    This really does look like it could be nasty. If you’re in a basement apartment, go stay with friends, if you can.
