Hurricanes cover a large area. It's unlikely a storm could evade ship and air traffic even in 1933. Of course, there is always an Admiral Halsey who steers his fleet through the center of the same typhoon twice.

full hurricanes maybe. of course sometimes they form well out in the eastern atlantic and die out there, and then there are questionable-nature storms in the subtropics... and the very weak or very flash-in-the-pan storms that move onshore in central america. there is a distribution bias in the historic database (i.e., number of storms on average in different parts of the basin in satellite/modern era vs. the older period). suggests the older data is missing some. great handle by the way. -HF
