Desert Flash Floods
Personnel traveling on White Sands Missile Range must be aware of the increase potential for flash floods during the rain or monsoon season. Flash floods can occur without adequate warning, partially due to significant amounts of rainfall along the mountains and precipitous terrain leading to low lying desert basins throughout the range area.
A seemingly insignificant rain shower along the Organ, San Andreas, or Oscura mountain ranges can prove deadly to unsuspecting individuals occupying mountain valleys, low lying terrain, range wetlands, and depressions.
Increase your situational awareness –
Check the local weather forecast throughout the day
Monitor current and changing weather conditions in your area.
Evacuate the area or moving to higher ground, if you are positioned in a potential flash flood area.
Slow down when driving in the rain. Be especially careful crossing water and runoff channels on roadways. If you cannot accurately assess the water depth – DO NOT cross a runoff channel.
