Hurricane Debby made landfall as a Category 1 storm along the FL Big Bend coast during the early morning of August 5, 2024. Prior to landfall, outer convective bands produced tornadoes across portions of northeast Florida on August 4th. Widespread flooding moved inland with Debby across the Suwannee River Valley and inland Southeast Georgia where flash flooding and moderate to major river flooding occurred.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 19:38 UTC.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
