Heavy Rains and Flash Flooding <br /> All tropical cyclones can produce widespread torrential rains often in excess of 6 inches.This rain can produce deadly <br /> and destructive floods.Heavy rain can trigger landslides and debris flows,especially in mountainous regions.Flash <br /> flooding,a rapid rise in water levels,can occur quickly due to intense rainfall. <br /> Intense rainfall is not directly related to the strength or winds of tropical cyclones but rather to the speed of <br /> movement and geography of the area affected.Slower moving storms produce more rainfall.Mountainous terrain also <br /> enhances rainfall from a tropical cyclone.Even the remnants of a tropical cyclone can produce heavy rains and flash <br /> flooding. <br /> IL <br /> J .+' ,-4 - 'Sri _ R�4 ' a.. •^ar�q;k <br /> 9 7 y'~• �._.- - A �.�-_ ,.
