Hurricanes

Turns out that the current streak (9-years) of no land-falling major hurricane in the US has a probability of occurring once every 177 years. If we get through this season (which had 1 major hurricane thus far, Danny, and was only projected to have 1 major hurricane) then that will be 10-years of such "luck".
