2,076 first-hand accounts of flood events in Louisiana, ranked by impact. Each is a NOAA-written narrative of the moment.
As high pressure over the East Coast refused to move, a storm system approached the ArkLaMiss from the west and stalled just to the west of the region on March 7th.

Read the full account →A stalled frontal boundary along with multiple impulses aloft lead to an extended duration of rain, thunderstorms, and even a couple tornadoes. Massive flooding occurred along the Mermentau River where rainfall totals exceeded one foot at some locations during the event.
Read the full account →Isaac entered the Gulf of Mexico as a tropical storm on August 26, moving northwest after crossing Haiti, Cuba and the Florida Straits. Isaac strengthened into a hurricane on the morning of the 28th when it was 75 miles south-southeast of the mouth of the Mississippi River.

Read the full account →A cut off upper low over West Texas pulled in deep moisture from the Pacific and gulf over a stalled frontal boundary that stretched from Southeast Texas across Central Louisiana. This produced large amounts of rainfall that lead to flash flooding.
Read the full account →A very slow moving area of low pressure moved west across South Louisiana. Very high moisture content and slow moving bands of rain generated efficient rain producing storms that left rainfall totals at some locations over 20 inches.
Read the full account →An upper level trough brought a cold front to the region. Ahead of this cold front, moisture levels through the atmospheric column increased to above the 90th percentile for this time of year.
