You are now in California and the U.S. category.

The last time two states went to war over water, it was 1934. The combatants were California and Arizona and the casus belli was the start of construction of Parker Dam, which would direct water from the Colorado River into California via the Colorado River Aqueduct.

The episode unfolded with a sort of Gilbert and Sullivan absurdity. Arizona’s governor, Benjamin Baker Moeur, dispatched a handful of National Guardsmen upriver in a ferryboat named the Julia B., which frontline correspondents dispatched to the river by The Times and other California newspapers happily dubbed the “Arizona Navy.”

It’s already late May. But parts of Northern California got another blast of rain and snow this weekend, helping the state’s drought relief efforts.

A spring storm dropped rain in parts of Northern California on Saturday afternoon, but it was less severe than the one a day earlier that dumped up to 13 inches of snow on a Sierra Nevada highway and hit the Sacramento area lightning, winds gusting to 40 mph and dime-sized hail.

Despite the strongest El Niño event on record and the well above normal amounts of rainfall it brought to Northern California, the worst category of drought (D4 Exceptional Drought) continues to persist throughout most of San Luis Obispo and Kern counties and all of Santa Barbara and Ventura counties.

Since the start of 2016, nearly all the long-range models have consistently advertised that a La Niña condition — which historically produces below average rainfall for the Central Coast — will develop in the eastern equatorial Pacific this upcoming winter.
