A series of powerful tornadoes swept across Sumter, Lake and Volusia counties during the early morning hours of February 2, 2007. A discontinuous swath of tornado damage was observed from near Wildwood in Sumter County to the town of Lady Lake (Lake County) to New Smyrna Beach (Volusia County). This was a distance of over 70 miles. A total of 21 fatalities occurred within Lake County. Central Florida was located in the warm sector ahead of an advancing cold front. Large scale lift was supported by a very strong jet aloft, with strong vertical shear. Instability increased overnight with temperatures and dew points increasing through the pre-dawn hours. A single long-tracked supercell thunderstorm traveled from Sumter County to the coastal waters of Volusia County during the early morning hours of February 2, 2007. Three tornadoes touched down along this track.

The mesocyclone that produced the Lady Lake tornado reintensified and produced a second F3 tornado in a rural area west southwest of Paisley. The tornado move east northeast at over 50 MPH toward the Lake Mack area just west of the St. Johns river. The tornado produced a quarter mile wide track across the Lake Mack area destroying 86 residences and damaging 144. Many mobile homes were completely destroyed. Thirteen people died in mobile homes.

The tornado that killed 13 people in the Lake Mack area of Lake County moved east across the St. Johns River, crossed into Volusia county at Lake Beresford and moved across Deland as an F3 tornado. It was still moving east northeast at 50 MPH as it damaged 277 and destroyed 106 residences in the Deland area. The tornado finally lifted about eight miles east of Deland along Highway 44. There were no fatalities in Volusia County but 42 people were injured.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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 General Thunderstorms Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 06:01 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

The radiosonde launches on either side of the tornado, from the nearest station that was launching then, drawn and analyzed the way Storm Lab does: the same diagram, the same parcel and shear definitions SPC's mesoanalysis uses.

The Melbourne radar (KMLB), 121 km away, was scanning. The volume nearest the touchdown began at 08:36 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.
