1000 simulations are run of all tracks that passed through the one degree box.
The 50th percentile (500th of the sorted 1000 simulations) of hurricane strength area (> 64 kt) and mainland landfalls are binned into 5 by 5 degree boxes and plotted.
Hurricane strength area is in units of 6 hour residence.
Mainland landfall is defined as an ocean to land crossing.
A white map indicates the 50th percentile of the entire area is zero.
Zero contours are indicated by a dashed line.
