California Drought Early Warning System
Drought in California is a common occurrence that can last for multiple years. The regional climate is characterized by a distinct dry season (approximately May to September) and wet season (October - April) defined by a few large precipitation events. Topography within the region creates a diverse set of climate conditions, from the snowy peaks of the Sierra Nevada Range to the Mojave Desert, to the mountains and valleys of the Basin and Range. Given the extreme variability, both spatially and temporally, efficiently using and effectively managing finite water resources is a high priority. Based on the many connections the two states share with respect to geography, climate, water, and drought, a joint CA-NV DEWS was developed to support enhanced drought early warning across the region and to build out NIDIS’s national drought early warning system.
