Los Angeles, CA – Halloween celebrations across Southern California could turn wet Saturday evening, October 31, as rain increases across Los Angeles, Ventura, Santa Barbara and San Luis Obispo counties, with the most widespread showers expected Saturday night into early Sunday.
According to the National Weather Service in Los Angeles/Oxnard, rainfall coverage will increase later Saturday afternoon before peaking overnight. Forecasters say some communities could remain dry or experience only light rain through early evening, but residents should prepare for wet outdoor activities.
Rain chances increase substantially between 3 and 6 p.m., with probabilities reaching 80% to 100% across portions of the region during the evening and overnight hours.
Los Angeles and Ventura counties face increasing rain chances through Saturday night, while Santa Barbara and San Luis Obispo counties could experience widespread rainfall earlier in the evening.
Most communities can expect rainfall totals between 0.25 and 0.75 inches. However, localized amounts of 1 to 2 inches are possible beneath heavier showers and across the San Gabriel Mountains.
Peak rainfall rates are generally forecast between 0.10 and 0.33 inches per hour, with isolated heavier downpours potentially reaching 0.50 inches per hour.
The National Weather Service says the risk of significant flooding remains low, although wet and ponded roads could create hazardous driving conditions.
Halloween trick or treaters and families attending outdoor events should prepare for possible rain, particularly during the evening hours when neighborhood activities are typically busiest.
Drivers are encouraged to reduce speeds, allow additional travel time and remain alert for standing water on roadways.
Rain chances are expected to decrease Sunday, November 1, as the weather system moves through the region.
Residents should continue monitoring updated forecasts as the timing and intensity of showers may vary by location.
