What the National Weather Service wrote

A Weatherflow Tempest mesonet station in Port Fourchon measured a thunderstorm wind gust of 42 mph or 37 knots.

The wider storm

A cold front that moved into the region on May 21st had stalled over the Louisiana coast by the 22nd. Strong daytime heating enhanced convective updrafts while temperatures aloft remain quite cool for the time of year. This environment was sufficient to support severe thunderstorm downdrafts over the local marine areas.

Began near Dulac - Xdul Weatherflow (29.1271, -90.2081).
