Flash Floods
Flash floods are sudden, intense floods caused by heavy rainfall, rapid snowmelt, or dam breaks. They occur with little warning, turning calm streams or dry areas into raging torrents within minutes. This dramatic surge of water can sweep away vehicles, destroy buildings, and pose significant risks to life and property. Flash floods highlight nature’s unpredictable and dangerous side, reminding us of the power and speed with which natural disasters can strike.
