September 10 and 11, 2017
- Irma was a Category 4 hurricane when the storm hit the Florida Keys, but its strength decreased to Category 2 as it moved north up the coast.
- Tropical storm conditions were experienced locally, which caused extensive flooding.
- The center of the storm was about 80 miles away as Irma passed Flagler County.
- Maximum wind gusts reached 78 mph in Flagler Beach, but the county did not experience sustained hurricane-force winds.
- The storm surge was 4 to 6 feet, and higher in localized areas of Flagler Beach because of the combination of rainfall — 10 to 14 inches — and king tides.
- There was one confirmed EF-0 tornado that traveled through Princess Place south of Marineland.
