Hurricane Michael
When did Hurricane Michael make landfall in Florida?
How many deaths were directly and indirectly caused by Hurricane Michael?
Which areas suffered the most damage from Hurricane Michael?
Hurricane Michael, large, catastrophic tropical cyclone that brought devastating wind damage, rain, and flooding to the Florida Panhandle and southwestern and central Georgia in early October 2018. Michael made landfall near Mexico Beach, Florida, on October 10, 2018, with maximum sustained winds peaking at 161 miles (259 km) per hour, making it the first category 5 (see Saffir-Simpson hurricane scale) hurricane on record to strike the Florida Panhandle. When it struck, it was the third-most intense Atlantic hurricane to hit the contiguous United States. Its relentless winds, storm surge, and rain caused widespread property and infrastructure damage and directly caused the deaths of 16 individuals in the United States, as well as indirectly causing the deaths of 43 additional individuals. The cost for repairs from the storm’s damage in the United States was estimated at $25 billion, with about $18.4 billion spent in Florida, $4.7 billion in Georgia, $1.1 billion in Alabama, and smaller amounts across South Carolina, North Carolina, and Virginia.
Formation, development, and path
Michael had a complex origin. Its genesis process began on October 1–2, when a broad area of disturbed weather in the Caribbean absorbed the remnants of Tropical Storm Kirk, a storm that had struck St. Lucia on September 28. The system became part of a large cyclonic gyre over Central America on or before October 5. On October 6 the gyre absorbed a smaller vortex from the Pacific over Central America. The system became more organized, and, by the early morning of October 7, it formed into a tropical depression about 130 miles (209 km) south of Cozumel, Mexico. Over the course of October 6–7, this precursor to Hurricane Michael produced an extended period of rainfall over parts of Central America, which led to freshwater flooding that reportedly caused the deaths of eight individuals in Honduras, four in Nicaragua, and three in El Salvador.
The tropical depression then intensified and was classified as a tropical storm by midday on October 7. It then strengthened to hurricane status as it passed into the Gulf of Mexico at 8:00 am local time (12:00 UTC) on October 8. Hurricane Michael was upgraded to a category 2 storm on the Saffir-Simpson hurricane scale as it moved just west of Cabo San Antonio, Cuba, later that day, causing power outages and damage to property and crops in western parts of the country.
Outside of a brief pause late on October 8, Hurricane Michael continued to intensify while turning north-northwestward and then northward between October 9 and 10. Within 48 hours Michael had gone from a category 1 to a category 4 hurricane. The eye made landfall, at category 5 intensity, southeast of Panama City, Florida, close to Tyndall Air Force Base near Mexico Beach at 1:30 pm local time (17:30 UTC) on October 10. Michael weakened as it moved northeastward through the central Florida Panhandle, and within a few hours it was a category 2 storm as the eye moved into southwestern Georgia. About 12:00 am local time (4:00 UTC) on October 11, Michael had weakened to a tropical storm. Moving northeastward, the center passed just west of Augusta and then continued into South Carolina about 7:00 am Eastern Daylight Time (11:00 UTC) on October 11, at which point the winds in the central core had dipped below tropical-storm force.
Michael moved northeastward across South Carolina for several hours before entering North Carolina, where it began its extratropical transition, which was complete by 8:00 pm local time (00:00 UTC) on October 11 (October 12 based on UTC). The storm then turned east-northeastward, passing Raleigh, North Carolina, and then Norfolk, Virginia, before entering the western Atlantic at 2:00 am local time (6:00 UTC) on October 12.
Over the next few days, westerly winds continued to push the system east-northeastward into the open ocean south of Nova Scotia and Newfoundland, with subsequent eastward motion carrying it into the northeastern Atlantic. The system then turned southeastward and southward before dissipating just west of northern Portugal on October 15.
Impact in the southeastern United States
The Florida Panhandle was severely impacted by Michael’s storm surge, which generated heights of an estimated 9 to 14 feet (3 to 4 meters) along the coast, from the southeast side of Tyndall Air Force Base to Port St. Joe. It washed out coastal highways in several locations and caused the drowning deaths of five individuals—three in or near Mexico Beach, one between Mexico Beach and Port St. Joe, and one near East Bay on the eastern side of Panama City. The combination of storm surge and high winds also caused widespread power outages and damage to numerous buildings and homes. In Mexico Beach, where the worst of the devastation occurred, nearly 94 percent of the structures within the city limits suffered some amount of damage, with about half being destroyed. In all, more than 46,500 structures were damaged in Bay county (where Mexico Beach is located), including 1,500 that were destroyed. In nearby Gulf county 1,200 structures were severely damaged and 985 were destroyed. Inland Florida suffered severe wind damage, and two individuals died because of falling trees. All 43 deaths indirectly caused by Hurricane Michael occurred in Florida and included those from traffic accidents or medical issues compounded by the storm, as well as falls during the cleanup after the hurricane.

In Georgia numerous homes were damaged or destroyed in Seminole and Dougherty counties, with Seminole county reporting damage to nearly all residences and Dougherty county reporting the destruction of 49 of the 3,000 homes that were damaged. A falling tree caused the death of one individual in Seminole county. Southwestern and central Georgia also experienced widespread power outages, as did parts of southeastern Alabama.
Although the storm’s destruction was comparatively limited in North Carolina and Virginia, it caused eight deaths—three in North Carolina from falling trees and five in Virginia because of freshwater flooding.
The World Meteorological Organization retired the name Michael in 2019.
