The storm will release rain from Wednesday, with mountain snow in Los Angeles County
The area is expected to emerge in the moisture this week as the rainy season begins in Southern California, which forecasters say could be the beginning of a wet parade.
The warm front arrived at the Central Coast late Tuesday and will spread south to Los Angeles on Wednesday that day, bringing moisture before the storm bears the brunt. Robbie Munroe, a meteorologist with the Oxnard National Weather Service, said most of the rain will be expected to arrive in Los Angeles County late Wednesday.
More rainfall is expected to be provided for colder Southern California landscapes next week. The region endured its driest history, beginning with the history of the rainy season, fueling one of the most destructive fire seasons ever.
As of Tuesday, downtown Los Angeles began raining 5.58 inches in the water year starting October 1. This is below the average of the water season (11.08 inches). The annual average is 14.25 inches.
“We’ve been catching up and it feels like it’s all winter from January to January,” Munro said. “February is still below normal, but at least that brings us closer to what we might see at this time of year.”
During this week’s storm, coastal areas are expected to be between one tenth of an inch and one inch of rain. The south-facing hillside can see 1 to 2 inches of rain. According to the Weather Bureau, two to five inches of snow may drop at an altitude above 4,500 feet.
The storm is expected to release strong winds. On Thursday, gusts could peak between 30 and 50 mph.
The weather system also brings the potential for thunderstorms, especially Wednesday to Thursday, which can bring heavy downpours, gusts of wind, lightning, small hail and even weak tornadoes.
Although forecasters expect moisture to be primarily beneficial, too much rainfall can lead to damage to the debris flow and the burn scars of Palisade and Eaton fires.
“We won’t keep raining. It’s going to be an episode, and there can be a lot of dryness between these episodes. “Don’t let the guards down after the first round of rain.” It may be back soon. ”
Peak rainfall rates can range from one tenth of an inch to one third of an inch per hour, and in some areas it can reach a half inch per hour. Experts say once rains are raining at a rate of half an inch per hour, the risk of mud and debris rising from burning hillsides increases.
According to the Weather Bureau, there are 10% to 20% chances of major flooding and debris flow in the burned areas of Los Angeles County.
“There is no guarantee at all, but there is a possibility,” Cohen said of the dangers in the burning area. “It’s something that’s really a concern because our confidence in the massive debris flow that happens may not be particularly high until it happens.”
The burning zone has seen the impact of wet weather this winter.
Heavy rains last month poured dirt and debris into the Pacific Coast Expressway (sweeping vehicles into the ocean) and forced the Topanga Canyon Boulevard between the Pacific Coast Expressway and Grand View Drive to close indefinitely.
However, this week’s storm is not that strong.
The system is also expected to bring fresh powder to the California mountains.
In Northern California, the Weather Service issued a winter weather consultation at altitude below 7,000 feet and 6 to 12 inches at altitude below 7,000 feet and 6 to 12 inches at altitude below 7,000 feet and 6 to 12 inches. The highest peak wind energy is expected to reach up to 55 mph.
In Southern California, the Weather Bureau issued a winter weather consultation for the mountains in Los Angeles, Santa Barbara and Ventura counties. The warning will last from 7 p.m. to 7 a.m. Wednesday, saying snowfall may be 3 to 6 inches altitude, except for the local maximum of 10 inches near Wrightwood.
According to the Weather Bureau, the height is 4,000 to 6,000 feet and up to 3 inches of dust can be seen.
The upcoming storm could help strengthen the state’s snow, which the snow bag suffered in the warm and dry winter. As of Tuesday, snowflakes (usually melting to provide a third of the state’s water) were 83% of the average at this time of year.
Munro said the wet parade could also help the region delay the backfire season.
“The longer we are in the spring, the more we’re we’re we’re we’re going to help us delay,” Munro said.
After Friday, the area may see a few days of dry weather, and then more rain returns on Sunday night. The system can rain in the rain Tuesday. Another storm is expected to arrive the next day after that, and will last until March 13, which may bring heavier rainfall, but the exact amount is uncertain.
