A storm system from Northern California brought rain to parts of Central California on Monday, but Los Angeles remained dry.
Showers have drenched parts of San Luis Obispo and Santa Barbara counties since Sunday. In Santa Barbara County, Sudden Peak received a total of 3.11 inches of rain and Rancho San Julian received a total of 4.07 inches. Santa Maria broke its daily record Monday with a preliminary rainfall of 1.71 inches. His previous record for the date was 0.16 inches, set in 1959.
In San Luis Obispo County, Oceano received a total of 1.74 inches and Arroyo Grande received 2.04 inches during the storm.
The rain has been held off by a slow-moving frontal system that has essentially stalled over the area and is maintaining moisture levels, said David Sweet, a meteorologist with the National Weather Service in Oxnard.
The storm system was forecast to “hang in there all day and not really move,” Sweet said Monday morning, adding that it will eventually weaken and dissipate. It was not expected to move further east of Santa Barbara.
Los Angeles has a 20 percent chance of seeing rain, Sweet said. “There are no surprises here,” Sweet added, even though it’s early in the rainy season.
The rain is coming from a low-lying storm system moving slowly down the California coast, forecasters said.
Rain started the week in the Bay Area, with wet conditions beginning Sunday; scattered showers could last through Wednesday. Lightning strikes were seen in Napa County on Monday.
“We just have an unusual deep low that’s causing some rain,” said Matt Mehly, lead meteorologist for the National Weather Service in the San Francisco Bay Area.
Rainfall totals varied across the area, though the mountains received the most rain, with the North Bay Coast Range getting 2 to 3½ inches, the Santa Cruz Mountains getting as much as 2.2 inches and Mining Ridge getting nearly 4 inches to the mountains of the central coast.
Strong winds and wind warnings led to fears of possible power outages on Sunday. Forecasters predicted some flooding along highways and hazardous local road conditions, including downed trees. There were no weather warnings on Monday.
September is typically the third driest month in California, according to the National Weather Service in the Bay Area. Mehly said the rain was a relief. “We’ve had a historic heat wave with a lot of wildfires, so the precipitation is welcome [across the state] to slow down the fires,” Mehly said. “It won’t be the end, but it’s a step in the right direction.”
Rain showers have brought welcome moisture to the Mosquito Fire, the state’s largest wildfire this year, and aided in the fight against it. As of Monday night, the blaze was 76,290 acres in El Dorado and Placer counties and was 39 percent contained — with an increase of 20 percent on Saturday, according to the California Department of Forestry and Fire Protection.
The rain also increased the risk of mudslides and flooding. The hurricane watch will be in effect in the area of the Komarnik fire until 12 noon on Wednesday.
Can a monsoon happen anywhere?
While many of the best-known monsoons are in Asia, monsoons can occur anywhere there is a seasonal difference in temperature between land and water. This is common in tropical and subtropical climates.
What qualifies as a monsoon? So what is monsoon? A monsoon is a large-scale weather pattern that involves a seasonal shift of wind over a region and is usually accompanied by an increase in atmospheric moisture and precipitation. When this particular weather pattern occurs, the time frame is defined as the “monsoon season.”
Do monsoons happen in America?

In fact, this monsoon may turn out to be the strongest ever in some places!

Where is a monsoon most likely to occur?
Monsoons are most often associated with the Indian Ocean. Monsoons always blow from cold to warm regions. The summer monsoon and winter monsoon determine the climate for most of India and Southeast Asia. The summer monsoon is associated with heavy rainfall.
Where do the monsoons come from?
The monsoon is driven by the sun, which heats land and the Pacific Ocean at different rates, with land surfaces warming faster than the ocean. Warm earth creates areas of low pressure as hot air rises. Once this pattern is established across the region, winds shift to fill the vacuum.
Where do monsoons occur most often what season are they prevalent?
Asia is known for having two monsoon seasons: the summer monsoon and the winter monsoon. The summer monsoon hits India the hardest, where urban areas prepare for flooding, sometimes up to a meter and a half of water.

Where does monsoon season occur in the US?
The North American monsoon is a complex weather process that brings moisture from the Gulf of California (and to a lesser extent the eastern Pacific and Gulf of Mexico) over northwestern Mexico and the southwestern United States, causing summer storms, especially at higher elevations.
