[Video] Grand Canyon Flash Flood: 1 Dead, About 15 Unaccounted For
GSM Official released this video on August 30, 2026, reporting a flash flood in the Grand Canyon: one person dead and about 15 still unaccounted for. Flash floods are a high-risk monsoon-season hazard in the canyon country of the U.S. Southwest, where narrow terrain can send water levels surging within minutes, leaving hikers little time to escape.
