2026 Tornado Season: No EF5s, 2,699 Warnings Issued
The 2026 tornado season has been active but has yet to produce an EF5 tornado, the most severe classification. As of September 15, 2026, the National Weather Service (NWS) has issued 2,699 tornado warnings across the United States. March was a particularly notable month, with two EF3 tornadoes, including Michigan's strongest in nearly 50 years. June saw the highest number of warnings at 696, while September experienced triple its usual severe weather activity. Despite the high volume of warnings, the strongest tornadoes of the year have been rated EF3, with no EF5s recorded since June 20, 2025, in Enderlin, North Dakota. The fall secondary tornado season, typically occurring in October and November, is expected to bring additional activity.
