...Drought Conditions Update for Southwestern California...

.SYNOPSIS...

Above normal precipitation in December 2021 could not overcome the
dryness of January through March 2022. As such, most areas in Southwest
California are experiencing near normal to below normal precipitation
during the current water. A water year is October 1 through September
30. At present, most locations within San Luis Obispo, Santa Barbara,
Ventura and Los Angeles Counties have had between 50% and 90% of normal
rainfall this water year. On the current US Drought Monitor Map, which
is a map updated on a weekly basis showing current drought related
conditions in the United States, San Luis Obispo, Santa Barbara,
Ventura, and Los Angeles Counties are shown in Severe (D2) and Extreme
(D3) drought categories. This depiction is the result of long term and
short term dryness.

Currently the U.S. Drought Monitor still classifies 100% of the state of
California in any dryness or drought category. The U.S. Drought
Monitor classifies dryness and drought into five categories of
increasing severity: Abnormally Dry (D0)...Moderate Drought
(D1)...Severe Drought (D2)...Extreme Drought (D3) ...and Exceptional
Drought (D4).
