Query: Year-ahead prediction of US landfalling hurricane numbers   We present a simple method for the year-ahead prediction of the number of
hurricanes making landfall in the US. The method is based on averages of
historical annual hurricane numbers, and we perform a backtesting study to find
the length of averaging window that would have given the best predictions in
the past.
