Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS JAX wrote it up.
Weak west-southwest flow allowed both sea breezes to be active with a collision likely near the U.S. Highway 301 corridor. Mid level dry air was noted as well as moderately cool 500 mb temperatures of -8 degrees C.

A RELATIVELY WET PERIOD IS EXPECTED IN THE SHORT TERM AS THE MID/UPPER LEVEL TROF OVER THE ERN U.S. CONTINUES TO SEND IMPULSES OF MOISTURE INTO THE FORECAST AREA WHILE THE LOW LEVEL SURFACE RIDGE SLOWLY BUILDS NORTHWARD INTO THE FORECAST AREA. LACK OF ANY SIGNIFICANT IMPULSE THIS AFTERNOON SHOULD KEEP MOST OF THE TSTM ACTIVITY SCATTERED WITH STILL THE CHANCE OF ISOLD STRONG TO SVR TSTMS NEAR THE SBRZ COLLISION BTWN U.S 301 AND I-95 THIS EVENING. OTHERWISE A RELATIVELY DEEP AND MOIST SOUTHWEST STEERING FLOW WILL SET-UP THROUGH THE END OF THE WEEK WITH PWATS AROUND 2 INCHES EACH DAY.
