The 2019 Water Year was off to a dry start in California-Nevada. According to the U.S. Drought Monitor, ~74% of California-Nevada is in moderate (D1) to extreme drought (D3) as of December 4, 2018. Extreme drought (D3) conditions began impacting Ventura-Santa Barbara counties while D1-D2 conditions expanded over the Sierras and northern coastal California. Precipitation at the end of November into early December improved some of these conditions.

Over the course of the 2018 Water Year (Oct. 2017 - Sept. 2018), drought crept back into California-Nevada. According to the U.S. Drought Monitor, drought conditions have not changed over the last 2 months except for expansion of severe drought (D3) at the Oregon and Utah borders. As of Sept. 25, ~48% of California-Nevada was in moderate to extreme drought and ~43% was abnormally dry. Current forecasts show most drought areas persisting into the early winter with above-normal temperatures likely.
From October 2017 to September 2018, the Southwestern U.S. experienced below-normal to record-low precipitation. Long-term precipitation deficits and record-high temperatures have contributed to very low streamflows and reservoir levels. Conditions favor the development of El Niño this winter, but significant drought is expected to persist in most of Utah and Colorado.
