Note that the joke isn't claiming that Florida dodged hurricanes for years before now. Note also the general irony of having a record year for hurricanes (and generally fucked-up weather all year) right before the vote whether or not to hang onto the administration that continues to deny that the climate is going wonky and that people seem to have had something to do with it. Then go look up the term "dark humor" and the phrase "whistling in the dark."
