With an already cold air mass in place, a cold front moved through the area on January 8th. An upper disturbance then passed over the area on January 9th, causing some areas from Tampa north to experience sleet and snow flurries mixed with the light rain. Very cold and very dry Arctic high pressure then built into the area causing temperatures to plummet into the teens and twenties across the area each morning from January 10th through January 12th, and remain below freezing for numerous hours each night. The morning of January 11th was the coldest of all the mornings. Numerous minimum temperature records were broken at several recording stations across the area each night.
The extent of the cold combined with the multiple day duration caused significant damage to crops across the area. Marine life also suffered greatly, with the aquaculture industry devastated and wildlife enduring numerous fish kills and rescue efforts for manatees and sea turtles due to the Gulf of Mexico water temperatures dropping into the upper 40s. Nearly 200 of the roughly 5,000 manatee population perished from the cold. There were 47 sea turtles rescued from local beaches, 10 of which perished from the cold. Saltwater snook, bonefish, and tarpon endured widespread fish kills and caused the Florida Fish and Wildlife Conservation Commission to extend the closed fishing seasons until September for snook and until April for bonefish and tarpon. Freshwater tilapia also suffered widespread kills, with some lakes reporting up to 95 percent of the population killed.
Estimates of the crop damage are listed below by county. Preliminary commodity losses were computed using data from the Florida Department of Agriculture. This data included the measurable loss of shipments from average for each commodity which led to an estimated $249.5 million in damage in Florida due to the freeze events in January. The largest impact was on the tomato crop with an estimated 5.1 million cases lost. Other losses in order of greatest impact included tangerines, oranges, bell peppers, snap beans and strawberries.
