(Originally published at 9:10 a.m. PDT October 13, 2018)

Significant amounts of rain accompanied by copious amounts of lightning fell in Southern California Friday night ahead of a predicted moderate Santa Ana wind event that is expected to begin Sunday afternoon and intensify on Monday and Tuesday.

Many areas from Los Angeles to San Diego received over half an inch and there is a chance it could continue on Saturday. Beneficial rains fell in most areas, but there was too much in some of the desert areas where flooding was reported in the Coachella Valley and Imperial County. Some of the highest totals included 1.54″ at Ocotillo Wells and 1.10″ at Indio.

Firefighting agencies have been preparing for the strong, dry Santa Ana winds by prepositioning air tankers in Southern California. They were heavily used Friday to quickly knock down the North Park Fire north of San Bernardino before it could burn more than 50 acres.
