Southland braces for heavy rain, flooding


LOS ANGELES (CNS) — The first of two storm systems brought light rain to parts of the Southland Tuesday, providing a preview of the second, more powerful system that forecaster­s say will give the region a more thorough dose of precipitat­ion.

In advance of the backto-back systems, the National Weather Service issued a flood watch that took effect across Los Angeles County at 10 p.m. Tuesday and continues until Thursday night.

Forecaster­s estimated that much of the Los Angeles area could receive 2 to 4 inches of rain during the “atmospheri­c river” event accompanyi­ng the second storm system, with 4 to 8 inches possible on south-facing foothill areas and coastal slopes. Rainfall rates of 0.3 to 0.6 inches per hour are expected in some areas, but if thundersto­rms develop, some areas could see rain falling at a rate of 1 inch per hour.

“Extensive roadway flooding, especially in low-lying areas, and flooding of creeks and streams are possible,” according to the weather service. “In addition, there will be the risk for flash flooding and debris flows in recent burn scars, especially the South Fire burn scar in Ventura County. Also, there will be the strong potential for rock and mudslide activity, especially on canyon and mountain roadways. Flooding and rock/mudslide activity may lead to significan­t travel delays and road closures. Increased flow in rivers and streams will bring an increased threat for swiftwater rescues.”

Los Angeles County Lifeguards warned people to exercise caution if they visit the beach.
