Though we absolutely needed this rain to soothe the drought, the torrential storms have led to flooding, road closures and numerous advisories. Rain with possible thunderstorms and hail will continue Monday, though rainfall should be considerably lighter than yesterday, according to the National Weather Service.

Downtown L.A. has seen 13.52 inches of rain since October 1, 2016. This is 216% of the normal amount of rain. At the Long Beach Airport, rainfall of 3.87 inches set a new record, according to the L.A. Times. As a result, parts of of the 710 Freeway in Long Beach and the 110 Freeway in Carson were closed for a time due to flooding, ABC 7 reports.

The NWS has issued a flash flood warning L.A. and Ventura counties until 6 p.m. today, with recent burn areas especially vulnerable to flash floods, debris flows and mudslides. Residents of about 120 homes around Santa Clarita near the site of the Sand Fire in July and 180 homes in Duarte near the site of the Fish Fire in June were evacuated, according to City News Service. So far, conditions have been reasonably stable and one Duarte resident told the L.A. Times, "The real problem is I can't take my son to Cheesecake Factory tonight." Those evacuation orders will be lifted around 10 a.m. this morning.

The NWS also warns of "rock and mudslides along canyon roads, urban and small stream flooding, significant travel delays, downed trees and isolated power outages, and dangerous winter driving conditions in the mountains."

Meanwhile, over 7,000 LADWP customers are without power due to the storm, with additional outages in other parts of L.A. and Orange counties.

It is definitely not an advisable time to go sailing. There is a small craft advisory in effect until 6 a.m. on Tuesday morning, as well as a high surf advisory until 6 p.m. Tuesday evening. A high surf warning is in effect until 10 p.m. Tuesday night in Orange County. The NWS advises people near the coast to stay out of the water and away from jetties and rocks, as large and sudden waves are a hazard. Forebodingly, folks are warned to "never turn your back on the ocean." People should also stay out of flood channels. Brian Humphrey of the LAFD has told LAist in the past that it's always illegal to hang out in a flood control channel, but that storms make them especially unsafe. Most serious and loss-of-life events occur the days following a storm.

Up in the San Gabriel Mountains, over a foot of snow is expected at elevations above 7,000 feet and it's going to be windy. At 3,500 and 4,500 feet, there may be one to two inches by this evening, and the Interstate 5 Tejon pass may also see one to two inches. Low visibility and ice will make it dangerous for drivers.

Here's a list of the current major road closures:

  • Angeles Forest Highway is closed from Aliso Canyon Road to Angeles Crest Highway.
  • Malibu Canyon Road from Malibu Crest Drive to Piuma Road.
  • Partial closures on Laurel Canyon Boulevard.

Come Tuesday, the forecast is mostly sunny.
