The latest Southern California storm brought some flooding, a tornado and trapped some cars in the snow overnight, with rain expected to continue through Saturday.<\/p>\n
In Orange County, a possible tornado or waterspout moved ashore around 10:15 p.m. Thursday in the eastern Dana Point Harbor, a witness reported to the National Weather Service. The wind \u201clofted a 12-foot segment of chain link fence with privacy fabric and threw it 70 feet across parking lot,\u201d the weather service said. <\/p>\n
There were numerous calls of flooding in the city of Westminster, police said, where an astonishing 1.84 inches of rain fell in a single hour, between 9:30 and 10:30 p.m. Thursday, according to the National Weather Service. One gauge in Garden Grove recorded 1.5 inches over the same hour. <\/p>\n
In Huntington Beach, a three-mile stretch of Pacific Coast Highway was closed \u2014 between Warner Avenue and Seapoint Street, just southwest of the Bolsa Chica Ecological Reserve \u2014 due to roadway flooding. Inches of rain also covered a section of Artesia Boulevard in Redondo Beach and a road in a Huntington Beach neighborhood, KABC-TV Channel 7 reported. <\/p>\n
Before dawn Friday, flooding and a rockslide hit Highway 330, the winding road north of Highland that leads to the San Bernardino Mountains. In Irvine, all lanes of the southbound Highway 133 offramp to Irvine Boulevard were flooded with several vehicles that were possible stuck, the weather service said; rain had been falling nearby at a rate of about half an inch per hour. <\/p>\n
In Big Bear Lake, a dozen vehicles were trapped in the snow along Highway 18 at Bear Valley Dam, authorities said. <\/p>\n
During the Friday morning commute, intense rainfall was continuing over parts of Los Angeles County, and a flood advisory was in effect. Doppler radar indicated areas of heavy rain, the National Weather Service office in Oxnard said. \u201cThis will cause urban and small stream flooding and overflowing of poor drainage areas,\u201d in areas including downtown L.A., the South Bay, the Westside, Long Beach and the San Gabriel Valley. <\/p>\n
One area of particular concern earlier Friday morning was a severe weather threat for southern L.A. County. The weather service office in Oxnard said the storm could rotate counterclockwise in that area, which could produce a small tornado. An area between Pasadena and the L.A. County-Orange County border was at risk, the weather service said late Thursday, although the area of risk could shift. <\/p>\n
There\u2019s a 10% to 20% chance of rain rates that could reach 1 inch per hour. Rain rates of half an inch or more per hour are enough to generate landslides. \u201cThis will be a much more scattered heavy rain event than the last event,\u201d the weather service said, \u201cso not all areas will get these rates, but the areas that do will could have significant hydrologic impacts,\u201d such as flooding. <\/p>\n
Later on Friday, there is a risk of a \u201csemi-wet Santa Ana event\u201d across parts of Los Angeles and Ventura counties. Typically, Santa Ana winds come from the north and east and are dry, capable of spreading wildfires; with this event, winds would come from the same direction, but with rain. <\/p>\n
In Los Angeles County, there will be a 60% to 70% chance of rain Friday morning, and a 30% to 50% chance on Friday afternoon and evening, with a 10% to 20% chance through Saturday morning. <\/p>\n
In Ventura County, there will be a 30% to 50% chance of rain Friday morning and afternoon, and a 10% to 20% chance Friday night. <\/p>\n
A winter storm warning was in effect for the San Bernardino County and Riverside County mountains through Friday afternoon, including in Big Bear. Heavy, wet snow was expected to fall at elevations above 6,500 feet. Snowfall of 4 to 8 inches was expected from 6,000 to 7,000 feet; 7 to 11 inches from 7,000 to 7,500 feet; and 12 to 16 inches above 7,500 feet. The city of Big Bear Lake is at an elevation of 6,752 feet above sea level.<\/p>\n
The storm is expected to continue through Saturday, with scattered snow showers and a chance of rain. Once the storms finally move out sometime on Saturday, the rest of the weekend is expected to be dry but cool. For the rest of the week, including Thanksgiving, temperatures are expected to warm up to seasonal norms and be rain-free through Black Friday, the weather service said. It\u2019s possible another storm could come sometime between Nov. 29 and Dec. 2.<\/p>\n
