Severe Weather Awareness Week (March 1-7, 2026) |
 |
| |
|
The National Weather Service (NWS), in cooperation with the Arkansas Division of Emergency Management (ADEM), has proclaimed March 1 to March 7, 2026 as Severe Weather Awareness Week in Arkansas. Citizens of the state are urged to prepare for the severe weather season. People are encouraged to use the week to review severe weather safety rules, and to understand the hazards associated with severe thunderstorms.

| In the picture: Tornadoes tend to be more frequent during the late winter/spring in Arkansas when La Niña (cooler than normal water along the equator in the Pacific Ocean) conditions exist. Three of the four most active years were La Niña years. |
|
| |
|
As of now, weak La Niña conditions are in place, meaning that water temperatures are a little cooler than normal along the equator in the Pacific Ocean. Research and local data indicate that tornadoes tend to be more frequent in Arkansas when La Niña is present. As the spring progresses, there should be a transition to neutral conditions (near normal water temperatures). Given this, the spring may not be overly active.

While the thought of a less active spring is good news, it does not mean we will not experience significant severe weather. In 2017 (a year featuring neutral conditions), a line of storms swept from Oklahoma across the northern half of Arkansas. The line reached Fort Smith (Sebastian County) by 100 am CST, and made it to Blytheville (Mississippi County) by 430 am CST. That's roughly 250 miles in less than four hours! Along the way, trees and power lines were downed and structures were damaged or destroyed. Straight-line wind gusts reached 60 to more than 90 mph. Intense lines of storms like this sometimes produce brief and weak tornadoes. During this event, at least six weak tornadoes (rated EF0/EF1) were counted. Such an outbreak could occur this year, so we need to be ready!

When it becomes necessary for severe weather warnings, there is something to mention. As expected wind gusts and hail sizes increase, we want to get your attention. There will be little commotion surrounding a standard Severe Thunderstorm Warning (60 mph winds/one inch hail). However, if 70 to 80 mph gusts or golf ball to tennis ball size hail are in the warning, it will be tagged as a "considerable" damage threat. For 80+ mph gusts or 2.75+ inch (baseball or larger) size hail, the damage tag will be labeled as "destructive". This tag will result in the activation of a Wireless Emergency Alert (WEA) through the Integrated Public Alert and Warning System (IPAWS), and this will go to cell phones within the warning polygon.
To help you plan for severe weather, the NWS will broadcast safety information on NOAA Weather Radio (NWR) and will transmit Public Information Statements (PNS) on news and weather wires.

| Tornadoes in Arkansas Since 1950 |
| Note: The number of tornadoes has doubled since the WSR-88D (Doppler Weather Radar) was installed in the early 1990s (39 tornadoes per year post Doppler versus 19 tornadoes pre Doppler). This is mainly due to better detection of rotation, especially with small/weak tornadoes. |

| In the picture: This is the cover of the "Severe Weather in Arkansas" guide featuring a home destroyed by a tornado (rated EF3) near Olvey (Boone County) early on 05/26/2024. |
| The busiest month of the year was April with twenty one tornadoes. The strongest tornadoes in 2025 were rated EF4, and there were two of them. Both of these occurred on March 14th and caused at least 6 injuries with thankfully no deaths. One of them had a path length of just over 117 miles. |
