Flash Flood — St. John the Baptist, Louisiana

2024-01-08 · near La Place, St. John the Baptist, Louisiana

Event narrative

Flash flooding was reported along Windsor Boulevard in the River Forest Subdivision. Water covered many streets and some garages got water in them.

Wider weather episode

Moisture rich air with near record precipitable water, for this time of year, surged north from the Gulf of Mexico across the local area as a warm front lifted northward. Increased lift from both the warm/moist airmass and front boundary primed the environment for robust updrafts. Mid and upper levels of the atmosphere began to cool as an upper level system approached the area. That combo of of instability and ample moisture created an environment able to sustain a variety of severe weather ranging from a tornado to damaging winds and hail.
