Weather tracker: severe storms and tornadoes hit parts of US

One tornado in Oklahoma was the first of 2024 to be rated as EF-4, the second most severe category

Severe thunderstorms affected parts of the US last week, spawning at least 129 tornadoes across midwestern and southern states between 25 and 28 April. The majority occurred on 26 April, with most touching down in Nebraska and Iowa.

Two that formed were particularly large and long-lived, lasting about an hour and reaching a mile in diameter, with surface wind speeds of about 160mph at their strongest. The first travelled over 31 miles across eastern Nebraska, causing severe damage in the Omaha suburb of Elkhorn. The second, which also developed secondary vortices, travelled almost 41 miles across western Iowa, and killed one person in Minden.
