Louisiana Storm Data: Hail & Wind History Since 2010
Deduplicated storm activity for Louisiana, fused from NWS warnings, storm reports, official records, and FEMA declarations.
Latest Louisiana hail and wind storms
- Last reported hail in Louisiana (0.75 in.+, screening): September 22, 2026 — 1.00 in. reported at Sterlington (Union Parish), SPC storm report.
- 2026 so far in Louisiana: 8 hail days and 58 wind days statewide (days with a storm report or station gust at the screening thresholds; warnings alone never count).

Louisiana storm facts
- StormAuditor's analysis of NOAA and National Weather Service records found 3,975 deduplicated storm events (wind, hail, tornado, and flood; NWS warning products included) in Louisiana in the 12 months ending October 21, 2026.
- Storm activity touched 64 of 64 Louisiana parishes over that period.
- The most impacted parish in Louisiana was Tangipahoa, with 141 events.
- The busiest day by event count in Louisiana was February 14, 2026, with 178 events.
Louisiana storm activity at a glance (last 12 months)
StormAuditor's consolidated public record currently shows 3,975 storm events impacting 64 of Louisiana's 64 parishes in the trailing 12 months: 1,917 wind events, 1,047 hail events, 228 tornado events, 783 flood events. Every count includes NWS warnings as well as observed reports, so tornado events mean tornado warnings and reports, not confirmed tornadoes.
Events are fused from National Weather Service warnings and Special Weather Statements, observed Local Storm Reports, official NCEI storm records, and FEMA disaster declarations, then consolidated into a single event table under the published methodology.
Wind covers thunderstorm and non-thunderstorm wind alike, so these counts measure something different from the NCEI entry counts in the history section below; the two are not comparable year to year. State totals also count NWS Special Weather Statements (radar-indicated hail or gusts below warning level); city pages leave those out.
Busiest days in Louisiana by event count
Ranked by the number of 12-month events, NWS warnings included, so a day with many warnings can outrank a day with larger hail.
- February 14, 2026 — 178 events incl. warnings (hail, tornado, wind)
- August 21, 2026 — 165 events incl. warnings (flood, hail, wind)
- March 15, 2026 — 140 events incl. warnings (hail, tornado, wind)
- March 11, 2026 — 121 events incl. warnings (hail, tornado, wind)
- June 18, 2026 — 119 events incl. warnings (flood, hail, tornado, wind)
Most impacted parishes
Events of every type for each county — wind, hail, tornado and flood, NWS warnings and Special Weather Statements included. City pages count wind and hail events only, so a county number on a city page is never higher than the number here.
- Tangipahoa — 141 events
- Bossier — 121 events
- St. Tammany — 116 events
- Caddo — 109 events
- Livingston — 103 events
- Rapides — 103 events
- Orleans — 102 events
- Jefferson — 98 events
Additional activity recorded under other NWS area names (forecast zones, tribal lands, and former census areas): Baton Rouge (1) · Feliciana (1).
How these numbers are counted
The storm numbers on this page are counted in four different ways, plus the free address check. Each answers a different question with its own size cutoffs, area and time span, so compare numbers within one group, not across groups.
- Storm days (latest hail and wind): A day in the last 12 months when at least one report anywhere in Louisiana showed hail 0.75 in. or larger or wind of 45 mph or more (StormAuditor screening thresholds). Reports are NWS storm reports from spotters, the public and officials, plus weather-station gusts, which count from 50 mph. A warning on its own never makes a storm day. The "City pages hit" column and each city's last reported hail apply the same rule within 25 miles of the city. The statewide columns count reports inside Louisiana only. City pages count reports within 25 miles of each city, which can reach into a neighboring state; those values name the other state, so a border city's value for a day can be higher than the Louisiana value.
- Storm-date pages (NWS severe): A storm-date page is published only when at least one report or station gust within 25 miles of a city met the National Weather Service severe criteria (hail 1.00 in. or larger, or wind 58 mph or more), at least two separate observations were logged, and the day ranks among the most significant. A storm report that relays an airport weather station's reading (the same station, the same gust and the same time) counts once, as the station reading. Not every storm day gets a page; when one does, the page and the storm-day table show the same largest hail and strongest gust.
- Events (12-month counts): Events count the Louisiana storm log: NWS warnings and Special Weather Statements (a lower-level NWS alert), storm reports (wind 50 mph+, hail 0.75 in.+), station gusts, NCEI entries and FEMA disaster declarations, for each county affected, floods included. One event is one place on one day, counted separately for each type (wind, hail, tornado, flood). A weather station or storm-report point counts once a day, at that day's highest reading, however many readings it filed; a place with hail and wind on the same day is two events. NWS warnings and Special Weather Statements count once per county per day, and NCEI entries and FEMA declarations once per place per day. A storm report that relays an airport weather station's reading (the same station, the same gust and the same time) counts once, as the station reading. The same report arriving through another feed (SPC or NCEI) is one record. The most impacted counties list uses this count. City pages count only wind and hail within 25 miles and leave out floods and Special Weather Statements, so city counts do not add up to the state total, and a city page's county count is a wind-and-hail count that is never higher than the same county's number here.
- NOAA history (since 2010): The official NOAA storm record (NCEI Storm Events) in Louisiana from January 1, 2010 to the day before the 12-month window starts: hail 0.50 in.+, thunderstorm wind 40 mph+ and tornadoes. It is a separate, older record with its own "storm days" (days with any entry), so its counts are not compared with the 12-month numbers.
- Free Report Snapshot: A free YES/NO estimate for one address, from radar and wind analysis at the property rather than area reports, at the same screening thresholds: hail 0.75 in. or wind 45 mph.

Louisiana hail and wind history in NOAA NCEI records, 2010–Oct. 2025
This section covers January 1, 2010 through October 20, 2025. Storms from October 21, 2025 on are in the 12-month summary above, so no date is counted in both.
NOAA's Storm Events Database holds 8,825 NCEI Storm Events entries in Louisiana for this period, on 891 separate storm days. Wind is the more common entry — 5,554 thunderstorm wind reports to 2,207 hail reports.
Hail and wind both peak in April, the month with 28% of the hail reports. December through February accounts for 122 storm days.
Storm days ranged from 45 in 2017 and 2021 to 65 in 2012 and 2023. Across 2022–2024, Louisiana averaged 58 storm days a year, above the 15-year average of 55.
The largest hail in these records for Louisiana was 4.25 in. (larger than grapefruit size), reported in 2010 and 2014 — most recently on December 23, 2014 in Catahoula Parish. Hail of 2 inches or more appears in 16 different years of this record, the latest being 2025 through Oct. 20.
Measured thunderstorm gusts topped out at 102 mph (St. Mary Parish, May 22, 2013). NCEI also lists 1,064 tornado entries in Louisiana — one entry per parish a tornado crossed.
- Average: 55 storm days a year (2010–2024)
- March and April: 46% of all hail reports
- Most hail reports in one year: 382 in 2023
- Hail of 1 in. or larger reported in every full year, 2010–2024
