What are the sources for hurricane risk?
Hurricane track data is obtained from publicly available USGS records. Atlantic hurricane coverage is from 1896 to the late 1990’s, covering a total of 950+ storms. Pacific hurricane coverage is from 1949 to the late 1990’s, covering a total of 660+ storms. Storm locations are tracked every six hours while the storm maintains the minimum wind speed required to be classified as a tropical storm. Along with location, the database includes information on wind speed and barometric pressure. The risk indexes are calculated using an area of decreasing severity along the path of the storm track and a width 100 miles to each side.
