• Tornadoes and Flash Flooding in Louisiana, March 20 to 28, 20121 injured · $11 million · EF2 · 19 eventsA cold front slowly moved into Southeast Texas and then into far west sections of Louisiana during the 20th. The cold front stalled upon entering Louisiana and then slowly moved back west through the evening before finally moving east in the morning of the 21st.
• Tornado and Flash Flooding in Louisiana, April 29 to 30, 2017$6.5 million · EF1 · 36 eventsWinds increased across Louisiana ahead of a system that was kicking out of West Texas. This produced a couple reports of tree damage. Later in the afternoon and into the night scattered reports of severe weather and flooding were received as the system moved through.
• Tornadoes and Flash Flooding in Louisiana, March 25 to 27, 2009$4.8 million · EF1 · 27 eventsSeveral episodes of widespread severe weather and heavy rainfall occurred from March 26th through the 28th as a series of strong upper air disturbances impacted the central gulf region as a meandering and nearly stationary frontal boundary drifted back and forth across the area.
• Hurricane and Tropical Storm in Louisiana, September 11 to 12, 2024$20 million · 8 eventsFrancine originated from a tropical wave that emerged off the West coast of Africa on August 28th. The wave traversed the tropical Atlantic Ocean with minimal organization, reaching the Leeward Islands by September 1st.
• Coastal Flood in Louisiana, October 5 to 8, 1996$5.5 million · 13 eventsCoastal flooding resulted from a sustained period of strong east winds. A tight pressure gradient persisted over the northern Gulf of Mexico due to the proximity of a strong high pressure system over the Southeast U.S. and Tropical Storm Josephine in the Central Gulf of Mexico.
• Tornadoes and Flash Flooding in Louisiana, May 19 to 21, 2019$434,000 · EF1 · 26 eventsA cold front moved into the region and stalled on the 19th. Multiple short waves moved across the region during the time causing severe weather and tornadoes.
• Tornadoes and Flash Flooding in Louisiana, June 5 to 7, 2019$266,000 · EF1 · 24 eventsDeep moisture streamed into the area ahead of an upper level trough and weak cold front. Precipitable water values ranged from 2 to 2.5 with the slow moving system which caused efficient rain producing storms and lead to flash flooding. Several tornadoes also occurred.
• Flash Flooding and Coastal Flood in Louisiana, March 9 to 11, 2016$750,000 · 0.88 in hail · 7 eventsA 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.
• Flash Flood and Coastal Flood in Louisiana, July 6 to 8, 2010$500,000 · 3 eventsA small tropical low moved inland along the south central Louisiana coast from late in the evening hours on July 5 into the early morning hours of July 6, then continued northwest across southwest Louisiana into east Texas from July 7 into July 8.
• Flash Flooding and Coastal Flood in Louisiana, November 9 to 13, 2024$165,000 · 8 eventsA frontal boundary moved into the region and stalled while Tropical Storm Rafael meandered in the gulf. Moisture from the decaying tropical cyclone streamed north across Louisiana. This produced heavy rain over the area that produced flooding.
• Coastal Flood in Louisiana, November 16 to 17, 1996$100,000 · 1 eventThree beach camps and 30 feet of shoreline was washed away by wave action when strong south winds in excess of 55 mph pushed in from the Gulf of Mexico. Two small cable boats and a jack-up rig were also damaged. The wind pushed water from the Gulf over La.
• Coastal Flood in Louisiana, April 29, 1998$75,000 · 1 eventStrong northeast winds and a developing low pressure system in the Gulf of Mexico resulted in minor coastal flooding in Cameron Parish. During high tides, water and debris was strewn across Highway 82 between Holly Beach and Johnson Bayou. Some beach erosion occurred as well.
• Tornadoes and Coastal Flood in Louisiana, October 25 to 26, 20151 injured · $25,000 · EF0 · 13 eventsLow pressure moved from south Texas to southwest Louisiana during the day and night of the 25th. A warm front associated with the low pressure provided the focus for isolated thunderstorms that produced two tornadoes over southeast Louisiana.
• Coastal Flood in Louisiana, April 29, 1998$50,000 · 1 eventMinor coastal flooding occurred at Burns Point and Cypremort Point in St. Mary Parish. Access roads to the Gulf of Mexico and some personal property had two to three feet of water covering them.
• Tornadoes and Coastal Flood in Louisiana, April 30, 2017EF1 · 5 eventsA squall line with embedded severe thunderstorms moved through the area ahead of a cold front. Strong onshore flow ahead of the front also led to coastal flooding.
• Coastal Flood in Louisiana, October 11 to 12, 1997$25,000 · 1 eventStrong southeast winds of 25 knots over a two day period led to minor coastal flooding in Cameron Parish. Highway 82 between Holly Beach and Johnson Bayou had debris thrown over it from tide action, including seaweed as deep as three feet in places.
• Tornadoes and Flash Flood in Louisiana, June 3 to 4, 2010$13,000 · EF0 · 12 eventsAn unusually strong upper level low slowly moved across southeast Texas and southwest Louisiana from June 3 into June 4. This system produced numerous showers and thunderstorms, which spawned a couple of tornadoes, wind damage, and coastal flooding across southwest Louisiana.
• Coastal Flood in Louisiana, October 5 to 7, 1996$20,000 · 1 eventCoastal flooding occurred along Highway 82 between Holly Beach and Johnson Bayou. The north side of the highway received minor damagedue to wave action. The Cameron tide gauge read between two and four feet above normal during this event.
• Coastal Flood in Louisiana, May 19 to 22, 202110 eventsStrong east-southeasterly pressure gradient flow between a strong high pressure over the mid-Atlantic and a weak surface low in the northwestern Gulf led to several days of coastal flooding across southeastern Louisiana.
• Coastal Flood and Astronomical Low Tide in Louisiana, October 25 to 26, 20156 eventsAs a low pressure system moved along the coast of Louisiana water levels rose above 3 feet above MLLW. Minor flooding was reported from Sabine Pass to Cypremort and Burns Points. As the low pressure departed the area north winds pushed water levels below normal.
• Coastal Flood and Astronomical Low Tide in Louisiana, January 22 to 25, 20236 eventsLow and high tidal variations occurred along the coast of Southwest Louisiana due to a pair of strong cold fronts and an area of low pressure.
• Coastal Flood and Hail in Louisiana, March 29 to 31, 20161.25 in hail · 5 eventsA warm front moved slowly inland from the gulf with isolated to scattered storms over a couple of days. A few were strong to severe. A strong onshore flow also accompanied this system pushing the tide above normal.
• Coastal Flood and Hail in Louisiana, April 13, 2019$3,000 · 1 in hail · 5 eventsA cold front moved into then stalled over South Louisiana during the 13th. A very unstable air mass was in place south of the boundary an a few severe storms developed. Strong south winds also drove the tides up along the coast.
• Coastal Flood in Louisiana, October 16 to 17, 20064 eventsPersistent strong southeast winds caused high tides across the southeast Louisiana coast resulting in coastal flooding.
• Flash Flooding and Coastal Flood in Louisiana, October 14 to 16, 20184 eventsA slow storm system moved across the region causing high tides and localized flooding.
