What the National Weather Service wrote

A mesonet site on Jekyll Island measured a wind gust of 52 mph.

The wider storm

Severe thunderstorms developed into the afternoon and evening as a frontal zone settled southward across SE GA and an impulse moved across the front. Significant heat and surface moisture in addition to steepening lapse rates ahead of the mid-level impulse created volatile surface-based instability which supported severe downbursts/outflows (50-70 mph) and hail. Given the near alignment of steering flow and the initiating boundary, the potential for waves or training convection created a flood threat as well.

Began near Cumberland Stafford (31.0500, -81.4100).
