Drought and Climate in Nevada
Meteorological drought, which is the dominance of abnormally dry weather, is a natural and persistent feature of Nevada's climate. Weather and climate are influenced and defined by a number of factors, including atmospheric pressure, winds, ocean currents, temperature and topography. Like many arid western states, Nevada relies on snowpack for a large portion of its water supply, including users in Southern Nevada who receive most of their water from the Colorado River. The timing of snowmelt (and consequently of peak flows in streams) is critically important for sustaining habitat and providing adequate water for wildlife, and rural, suburban, and urban residents.
