For the first time since January 2017, an event including both flooding and tornadoes impacted our area starting on February 11, 2018. Two tornadoes touched down across inland portions of the Florida Panhandle before sunrise, followed by persistent heavy rainfall that resulted in flooding at several river sites. As an upper level trough dug southward across the western and central U.S., southerly flow drew moisture from the Gulf of Mexico northward into the tri-state area over the weekend. Upper air soundings measured this increased moisture with precipitable water values around 1.5 inches on Sunday, well above the 90th percentile and a record for the 12z February 11 sounding, although the record for that date and time are below the average max for this time of year. With a cold front and upper level trough west of the area, the persistent deep layer moisture helped to create a favorable set-up for high rainfall amounts. This wet pattern resulted in copious amounts of rainfall across the tri-state region. The highest rainfall amounts were across the Florida Panhandle where 8 to 10 inches fell with localized areas receiving more than 10 inches across coastal Walton and Bay counties. The highest observed rainfall total was in Walton County, where a 48-hour rainfall total of 11.45 inches was recorded. Across southeast Alabama and portions of southwest Georgia, widespread 6 to 8 inches of rain fell. While one Flash Flood Warning was issued, the majority of the impacts from this event were from moderate rainfall rates over a prolonged period of time as convection trained across the tri-state area. These high rainfall totals resulted in numerous road closures across the Florida Panhandle from water covered roads and washed out roadways. In addition, a few roads were closed across southeast Alabama.

A tornado touched down in Holmes county and tracked through the south central part of the county north of Caryville and northwest of Bonifay. Two barns were destroyed and one brick carport that was attached to a house was destroyed. The roof of this house was mostly gone. There was one minor injury. The tornado was rated EF1 with peak winds estimated at 110 mph. Damage cost was estimated.

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 Marginal Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 05:57 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.
