Southern California Floods and Flood Watch: Halloween Storm Brings Rain to Los Angeles, Then Clears Sunday

The storm system that moved into Southern California over Halloween weekend brought widespread showers and cooler temperatures across Los Angeles County, with rainfall projected to peak between Saturday night and Sunday morning, according to the National Weather Service. Forecasters expected most areas to receive between a quarter of an inch and an inch of rain, with up to 2 inches possible on favored mountain slopes, and rainfall rates of 0.10 to 0.33 inch per hour.

The flood risk in Los Angeles stayed limited in the coverage read Sunday morning. The weather service said the heaviest rainfall Saturday night and Sunday looked to remain south of Los Angeles County, flood watches were up for central Arizona including Phoenix, and Southern California faced about a 5 percent chance of excessive rain in the Weather Prediction Center analysis reported by Bloomberg. A coastal flood advisory for Orange County expired at 2 p.m. Friday, though high tides just above 6 feet could still produce minor tidal overflow during the weekend, forecasters said.

The rain was expected to taper to scattered showers Sunday morning and become increasingly isolated Sunday afternoon, with most precipitation ending by Sunday night. The station's own weather feed on Sunday morning showed 60.1 degrees and overcast skies in Los Angeles, a Sunday high of 68.1 with a 76 percent precipitation chance early in the day, then a dry Monday at 73.7 degrees with no precipitation expected, warming through the week. Dry and warmer weather is also the weather service outlook for Monday and Tuesday, with a chance of showers returning Wednesday.
