With the current (Wednesday PM) track models showing Danny skirting the North Carolina shoreline and heading toward southeastern New England, I put together a list of similar storms from the ICAT Damage Estimator database.
Alma, 1962The average damage for these storms if they all struck in 2009 is about $6 Billion per storm. However, these storms made landfall at varying strengths, from Tropical Storm to Category Three. Since Danny is projected to be a Category One storm during the time of highest impact to land, we can massage the historical damages to see how much damage the storms would cause if they were all Category One storms. From our 2008 paper in the Natural Hazards Review:
Storm #7, 1944
Damage from Category Two = 6x the damage from Category One
Damage from Category Three = 18x the damage from Category One
Thanks for reading.Here is a screenshot of the analogous storms:
