"La Niña definitely was a bust," said Bill Patzert, a climatologist at the Jet Propulsion Laboratory in La Cañada Flintridge and one of several meteorologists who predicted last fall that La Niña, a climatological phenomenon marked by cold ocean-surface temperatures, would bring a drier-than-normal rainy season.
The Arctic storm that passed through the region Sunday set daily rainfall records in many communities. In downtown L.A., 2.42 inches had fallen by 8 a.m. Monday, about an inch more than the previous record set in 1943. Camarillo Airport had its wettest calendar day on record for March, with 4.91 inches; and Santa Barbara saw 5.23 inches, an all-time record.
Downtown L.A. has logged about 18.5 inches of precipitation since the rainy season began. That's more than 3 inches over its average for the whole season, which ends June 30, said Stuart Seto of the National Weather Service in Oxnard.
More showers are forecast for Wednesday, Thursday and possibly Friday, though precipitation will be considerably lighter than Sunday's deluge, Seto said. Saturday should be partly cloudy, with afternoon clearing.
On Sunday, hurricane-force wind gusts up to 98 mph roared through mountain passes, while gusts between 50 and 60 mph toppled trees throughout Southern California's urban landscape. Flowing mud swamped a retaining wall in Woodland Hills, forcing the overnight evacuation of 12 homes.
In hard-hit Santa Barbara County, sheriff's deputies rescued 18 people who had become stranded near Nira Campground as rivers swelled into raging torrents. Twelve children and six adults from Boy Scout troops in Lompoc and Camarillo were flown to Santa Ynez Airport and checked for hypothermia. The campers were cold and hungry but otherwise uninjured, authorities said.
