The latest GFS (Global Forecast System) model run shows Hurricane Matthew impacting Florida twice. While double landfalls are rare Florida has seen this occur 7 times in the past.
Unnamed CAT 3 October 18 1906 with winds at 105 knots hitting Marathon Fl (1st landfall)/Near Flamingo which is the southernmost headquarters of Everglades National Park, in Monroe County, Florida. This was point of the second landfall.
Great Miami Hurricane which was a CAT 4 made landfall on September 18th and 20th 1926 with wind speeds at 125 knots. Palmetto Bay (1st landfall)/Orange Beach, AL (2nd landfall)
While the second landfall did not go out to sea and back again to hit Florida a second time, it did have a dramatic impact on both eastern and western portions of the state
Unnamed CAT 4 September 15 1945 saw winds at 115 knots that struck North Key Largo (1st landfall)/Florida City (2nd landfall)
Unnamed CAT 4 hit September 21–22 1948 with winds at 115 knots and arrived in Saddlebunch Keys which are a series of mangrove islands about 7 miles east of Key West, Florida(1st landfall)/Near Chokoloskee which is part of the Naples–Marco Island area (2nd landfall).

Who could forget hurricane Andrew which was CAT 5 hurricane that made landfall on August 24 1992 and had wind speeds measured at 145 knots arriving at Elliott Key (1st landfall)/Near Homestead (2nd landfall). Elliott Key is the northernmost of the true Florida Keys, and the largest key north of Key Largo. It is located entirely within Biscayne National Park, in Miami-Dade County, Florida, east of Homestead, Florida.
Finally Hurricane Charley a strong CAT 4 storm that made landfall on August 13 2004 with wind speeds at 130 knots arriving in Cayo Costa (1st landfall)/Near Punta Gorda (2nd landfall). Cayo Costa is located west of Cape Coral and just north of North Captiva Island.
Could Hurricane Matthew become part of this family of multiple landfall hurricanes? It certainly looks like it could but there is still a lot of uncertainty at the moment. What we do know is the time to take action is NOW.
