The 3-month precipitation outlook shows above-average probability for much of the American West, including Colorado, source of crucial Colorado River water. Southern California will get more rain, however the rest of the state, where most of the water storage is, will get normal or less. This is a three-month outlook for Oct-Dec, and does not appear to factor in the building and powerful El Nino. Or maybe it does and assumes it will not hit central and northern California. Hmm.
Maven’s Notebook, a key source for California water news, has a plethora of state and national maps about water, including reservoir and general water conditions for California.
