In the United States, the first four months of 2025 have witnessed significant natural disaster activity. A slow-moving weather system and stationary front triggered both a widespread tornado outbreak and historic flash flooding across the Southern and Midwestern United States from April 2-7. The severe weather outbreak spanned parts of the lower Mississippi Valley into the Mid-South and lower Ohio Valley, before moving into the Southeast on April 6, bringing numerous tornadoes, widespread damaging winds, and large hail.
Between January 1 and April 7, 2025, the United States has experienced 461 reported tornadoes, including 59 that were rated EF-2 or higher. Mid-March was particularly devastating, with more than 100 tornadoes reported on March 14 and 15 alone, marking the deadliest tornado outbreak since 2021. The weather system responsible began as an atmospheric river in Southern California, causing mudslides that trapped people and vehicles.
As this system moved eastward, Texas, Oklahoma, and Kansas experienced wildfires linked to hurricane-force winds starting March 14. These powerful winds also led to deadly dust storms that severely reduced visibility on roads and highways. In Oklahoma, over 130 wildfires spread rapidly, burning approximately 200,000 acres in less than two days and damaging hundreds of structures, including at least 400 homes. In Stillwater, 74 homes were completely destroyed, prompting Governor Stitt to declare an emergency in 12 counties.
Mississippi saw severe weather events across 21 counties on March 14 and 15, resulting in six fatalities, three missing persons, and 29 injuries. Arkansas experienced two nighttime EF-4 tornadoes on March 14, with the Diaz tornado reaching winds of 190 mph, nearly qualifying as an EF-5, while the Larkin tornado had winds of 170 mph.
January saw devastating wildfires in Southern California causing 30 deaths, with the Eaton Fire burning over 14,000 acres and the Palisades Fire consuming more than 23,000 acres, becoming the second and third most destructive wildfires in California history.
Despite this destructive start to the year, as of April 8, there have been no confirmed weather or climate disaster events with losses exceeding $1 billion to affect the United States in 2025, according to the National Centers for Environmental Information.
