Hurricane Debby made landfall north of the local area along the Big Bend region of Florida near Steinhatchee around 7 AM EST on August 5th as a Category 1 hurricane with maximum sustained winds of 80 mph and a minimum pressure of 979 mb. Despite Debby���s track west of the Florida peninsula, impacts overspread the area from coastal locations spreading inland.|Storm surge affected the immediate coast from Ft. Myers northward through Cedar Key, where water levels peaked over 4 feet above normally dry ground across the upper Nature Coast and the Cedar Key area. Wind gusts of up to 60 to 70 mph affected much of the western Florida coast, with the strongest winds occurring along immediate coastal areas from around Tampa and St. Petersburg northward across Nature Coast locations, producing generally minor damage along with power outages. Torrential rainfall accompanied Debby as the rainbands east of its center moved across the area. Totals as high as 15 to 20 inches were reported, with hardest hit west-central and southwest Florida areas requiring numerous water rescues from flooded vehicles and homes as a result of extensive flash flooding and subsequent river flooding, and at least one official river gauge site established a new record crest. Multiple supercells embedded within outer rain bands east of Debby���s center produced at least 3 tornadoes across the area, however, associated damage remained relatively minor. |Debby���s overall impacts across the western Florida peninsula resulted in 2 direct fatalities and 3 indirect fatalities, with numerous homes and additional businesses receiving damage from freshwater flash and river flooding.

A supercell embedded within an outer rainband associated with Tropical Storm Debby produced a waterspout as it passed west of Treasure Island around 17:44 EST, that was captured on a nearby webcam. The waterspout continued northward, crossing the coast near Madeira Beach in Pinellas County around 17:50 EST, where residents reported minor damage to fencing and a trailer in the Boca Ciega Point community. Radar indicated the circulation weakened shortly thereafter with the tornado estimated to have dissipated around 17:53 EST southwest of Seminole. Maximum winds were estimated around 80 mph.

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.
