Worst Winter Flood in 20 Years

The flooding over the last couple of days was likely the worst event in Acadiana over the last 20 years. And this flood beat the 1993 Lafayette, St Landry & Vermilion because of the widespread nature of the flooding.

Rainfall totals in the area were nearly uniformly 8-12" across Acadiana, with areas experiencing severe flooding of 3-4ft and hundreds of homes and business inundated.

Not all areas flooded however, highlighting the fact that it's not necessarily how much, but how fast the rain falls over a period of time.

Most areas that experienced major flooding got most of the rain in a 12-18hr time frame while areas such as Lafayette, which received 7-9" over a 48 hour period experienced minor flooding. The Vermilion River however, has crested at one of it's higher points since 1993, with water levels at Surrey Street near 14ft.

Severe flooding and more than 60 water rescues were reported in Acadia, Evangeline, St Landry and portions of Vermilion Parish where most of the rain came in 24 hours or less.

On top of the flooding conditions, tornadic storms were also reported near Gueydan Wednesday evening, and in/near Breaux Bridge, Near New Iberia & Loreauville Thursday morning with damage to more than 30 homes reported. The tornadoes were EF1 strength with 86-110mph winds.

Flood Warnings conitnue for many areas in Acadiana through this evening as the high water will slowly recede due to the saturated grounds from this rainfall and a very wet December. Water in many areas may not completely recede for days.

The weather pattern will break only briefly with slight rain chances back by Friday evening into Saturday as a warm front moves back to the north from the Gulf of Mexico.

More wet weather is in the forecast Sunday into early next week as a nearly stationary frontal boundary will interact with the active sub-tropical jet-stream.

While the next series of systems do not appear to be as robust/severe as this week's system, prolonged rain chances and even a few inches of rain will add insult to injury to Acadiana's ongoing flood issues.
