 According to the National Weather Service, in the Florida Keys and Key West there is no known occurrence of snow flurries since the settlement of the region (at least 300 years).In Miami, Ft. Lauderdale, and Palm Beach there is only one known report in more than 200 years of snow flurries observed in the air, this occurred on January 1977 (though debate exists as to if this was rime or snow).In any event, Miami, Ft. Lauderdale, and Palm Beach have not seen snow flurries before or since this 1977 event.
