![]() ![]() Heavy rainfall caused widespread flooding across the area resulting in a nationwide power outage. As Ian rapidly intensified into a Category 3 hurricane, it made landfall in western Cuba. On the morning of September 23, the wave had enough organization to be designated as a tropical depression, after which it strengthened into Tropical Storm Ian early the next day while it was southeast of Jamaica. The wave moved into the Caribbean Sea on September 21 bringing heavy rain and gusty winds to Trinidad and Tobago, the ABC islands, and the northern coast of South America. Ian originated from a tropical wave that moved off the coast of Western Africa and across the central tropical Atlantic towards the Windward Islands. Ian was the first Category 5 hurricane in the Atlantic since Lorenzo in 2019, and the fifth since 2016 to reach that strength before making landfall in the contiguous United States. ![]() Ian was the ninth named storm, fourth hurricane, and second major hurricane of the 2022 Atlantic hurricane season. Ian caused widespread damage across western Cuba, Florida, and the Carolinas. Hurricane Ian was a deadly and extremely destructive Category 5 Atlantic hurricane, which was the third-costliest weather disaster on record, the deadliest hurricane to strike the state of Florida since the 1935 Labor Day hurricane, and the strongest hurricane to make landfall in Florida since Michael in 2018. Part of the 2022 Atlantic hurricane season Trinidad and Tobago, Venezuela, Colombia, ABC islands, Jamaica, Cayman Islands, Cuba, Southeast United States (especially Florida and The Carolinas) ( Third-costliest tropical cyclone on record costliest in Floridan history) No tornadoes were confirmed.Ian at peak intensity while approaching southwest Florida on September 28 Interestingly, some of the highest inundation occurred farther inland away from the immediate coast! Click here for the USGS's Flood Event Viewer. Geological Survey indicate inundation (i.e., water depths above ground) was generally about 1-2 feet in most areas with locally higher amounts up to ~3.75 feet, mainly in Beaufort County, SC. Surveys and measurements obtained from the U.S. Click here for a map of the highest water levels recorded for many other areas along the U.S. The greatest storm surge (storm tide minus the astronomical tide) at Fort Pulaski and Charleston was 7.69 feet and 6.2 feet, respectively, although these did not occur at the same times as the highest storm tides. ![]() The peak storm tide in Charleston Harbor was 9.29 feet MLLW / ~3.5 feet MHHW at 0648 UTC (248 AM EDT), which is the third highest level on record to date. Preliminarily, the maximum storm tide (astronomical tide + storm surge) was 12.56 feet Mean Lower Low Water (MLLW) / ~5.1 feet Mean Higher High Water (MHHW) at 0742 UTC (342 AM EDT) on October 8 at Fort Pulaski, GA, which was the highest level recorded to date.

The storm brought significant inundation from storm surge along and near the coast, rainfall-induced freshwater flooding, river flooding and hurricane-force wind gusts to portions of southeast GA and southeast SC.

Hurricane Matthew moved north off the Florida east coast as a major hurricane before weakening to a Category 2 hurricane off the Georgia coast and then eventually making landfall around Cape Romain, South Carolina as a Category 1 hurricane during the late morning hours on October 8.
