When was the last damaging storm in Beaver County?

The most recent record with damage, injuries or deaths is the June 25, 2026 tornado ($2,000 in damage in 2025 dollars).

Most of the tornado path was estimated by triangulating the location using chaser video/pictures and utilizing radar data. Toward the end of the life cycle of the tornado, after becoming rain wrapped and weakening, the tornado did encounter some damage indicators. Damage included large tree limbs which were snapped and one uprooted tree, all of which were around an old dilapidated homestead. Adjacent power lines were not damaged and this also provided clues to the intensity toward the end of the life-cycle. Radar imagery and video suggests the tornado was potentially stronger earlier in the track while in open grasslands. Maximum width was also estimated using photos and video. The maximum estimated wind speeds were 85mph.
