California Drought Early Warning System

Conditions for the week of December 5-11, 2018

Moderate to heavy precipitation fell in the Mojave Desert region of California and Arizona, giving some of these areas 10-25% of their annual precipitation. This lessened long-term deficits in southeastern California and parts of southwestern Arizona, leading to widespread one-category improvements. Moderate drought also was removed from the San Francisco Bay to the Central Valley area, where short- and long-term precipitation deficits had been reduced enough to bring them out of moderate drought.
