I've had a bunch of calls today, presumably following up from Nate Silver's post at the NYT, on potential damage from Irene.
I have used the ICAT Damage Estimator to look at all storms that fall within the spread of the various model projections (displayed above, as of 9AM MT) and here are the top 6 storms that come up.
|New England||Sep 21,1938||8||46,160,000,000||306,000,000||NY||2||100|
|Storm 7 in 1944||Sep 14,1944||31||10,670,000,000||90,000,000||NY||1||85|
|Storm 7 in 1944||Sep 14,1944||36||8,320,000,000||10,000,000||NC||2||105|
|Storm 8 in 1933||Aug 23,1933||52||4,880,000,000||27,000,000||NC||1||80|
None of the storms is really a good analogue. We should expect to see damage along the entire eastern seaboard, as well as a considerable amount of damage from inland flooding (not included in these numbers).
It wouldn't be anything more than a guess to speculate at this point on Irene's total impact, but it does seem safe to say that it's effects will be widespread and the damage total considerable.
