The toll

Deaths: 0
Injuries: 0
Property damage: None recorded
Crop damage: None recorded
Events: 1

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.

What happened

The episode as NWS JAX wrote it up.

The remnant circulation of T.S. Lee moved across the deep south during the day. Dynamical forcing and high moisture content (precipitable water values over 2 inches across the region) enabled scattered storms to form across the forecast area during the late afternoon and evening when surface based instability was high.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Jacksonville, FL wrote its last area forecast discussion before the first event at Sep 5, 1:38 PM EST, 3 hours 42 minutes earlier.
