Is there a second tornado season in Louisiana?
Yes. Besides the spring peak, Louisiana has a late-autumn and winter season: November to February brought 33% of its tornadoes (445 in 1996–2025), and January is the busiest of those months. Cool-season tornadoes in the South ride a strong winter jet stream and warm, moist air from the Gulf of Mexico. They often move fast, can come at night, and may be hidden by rain, so a warning may give less time to act. See winter tornadoes in the Southeast.
What time of day tornadoes hit Louisiana
The most common hour for a tornado to touch down in Louisiana is 3 pm to 4 pm (local standard time). 40% came between 6 pm and 6 am, when it is dark for much of the year and many people are asleep. A weather radio or phone alerts that can wake you matter most where night tornadoes are common.

Tornado watch or tornado warning?
- Tornado watch: conditions are right for tornadoes in and near the watch area, often parts of several states, for several hours. Issued by NOAA's Storm Prediction Center. Be ready and know where you would shelter.
- Tornado warning: a tornado has been seen or is shown by radar and threatens the warned area now. Issued by the local National Weather Service office, usually for less than an hour. Go to shelter at once: a basement, or an inside room with no windows on the lowest floor.
- Tornado emergency: the most serious wording the Weather Service can put in a warning, used when a confirmed, damaging tornado is heading for a town or city.

About this data
Data: NOAA SPC tornado database, years 1996–2025 (records since 1950). Source: the tornado file of the NOAA Storm Prediction Center's Severe Weather Database (1950-2025_all_tornadoes.csv), a US Government work in the public domain, spc.noaa.gov/wcm. Built 2026-10-18.
- Months, times of day, averages and the EF-scale mix cover the latest 30 full years in the database. The strongest and deadliest lists go back to 1950, when the database starts.
- A tornado that crossed a state line is counted in every state it touched, with the deaths and injuries in each state, as the Storm Prediction Center advises. National totals count each tornado once.
- Ratings before February 2007 are on the Fujita (F) scale and later ones on the Enhanced Fujita (EF) scale. "EFU" means the tornado could not be rated, usually because it hit nothing that could be surveyed.
- Times are local standard time; the county is the first county on the tornado's path. More tornadoes are reported now than in the 1950s because of radar, spotters and phone cameras, so old and new counts are not directly comparable.
- This is history, not a forecast. Any month can bring a tornado; follow your local National Weather Service office.

A tornado warning means a tornado has been seen or shown by radar and is a threat to the warned area now; it is issued by the local National Weather Service office for a much smaller area, usually for less than an hour.
