San Francisco reached a gust of 60 mph Wednesday evening while Oakland wasn't too far behind at 59 mph. So far, Eureka recorded a gust of 66 mph, forcing the closure of an 18-mile stretch of Highway 101 in Humboldt County due to multiple downed trees.Ĭalifornia's State Route 1 was closed for a period Wednesday in Mendocino County south of Gallaway due to downed trees. In Southern California, gusts from 50- to 70-mph are likely in the mountains and central coastal regions. High Wind warnings span much of Central California into Thursday morning for gusts between 50 and 60 mph in the San Francisco Bay Area, 60- to 70-mph gusts in the Sacramento Valley and 65- to 70-mph gusts possible along the coastal and mountainous regions. WHEN STORMS ‘BOMB OUT’: EXPLAINING HOW A BOMB CYCLONE FORMS Meanwhile, the bomb cyclone will create a tremendous difference in pressure across regions, leading to widespread high-wind events that could last for several hours. Santa Cruz County, which sits along the central California coast, has already declared a local state of emergency before Wednesday's storm arrived as the county suffered more than $10 million in damage from last weekend's atmospheric river storm.ĪTMOSPHERIC RIVER TURNS DEADLY AS IT SLAMS CALIFORNIA WITH FLOODING, MUDSLIDES 'Likely loss of human life' from atmospheric river impacts Since atmospheric rivers have been dropping near-record amounts of rain across California since before the Christmas holiday – as much as 5 to 12 inches – the additional water will have nowhere to go. As a result, numerous instances of flash flooding and mudslides are expected.Ĭonsiderable and life-threatening flooding is especially possible along the northern and central California coast. Rivers across the state are forecast to rise into flood stage. "We are seeing street flooding occurring on multiple streets throughout the City of Los Angeles," Los Angeles Police tweeted Thursday morning, adding the Sepulveda Basin had been shut down due to high water levels. The San Francisco Bay Area, which saw its second-wettest day on New Year's Eve, could see an additional 2 to 5 inches of rain with locally higher amounts.Įven the Los Angeles area could have 2 to 4 inches of rain – with 4 to 8 inches of rain possible in the Southern California mountains – by the time the storm system moves through. Some areas along the Northern and Central California coast could see 5 to 8 inches of rain, while farther inland, rainfall totals in the mountains and their foothills could approach 8 to 12 inches in some spots. Of particular concern are the potential for debris and mudflows where heavy rain falls in areas burned by major wildfires in the state over the past few years. Significant threat of widespread flooding from atmospheric riverįlood watches span much of the state, from near the Oregon- California border to just north of the Los Angeles area. Think of this as a narrow pipeline of moisture that originates in the tropics. This specific type of atmospheric river, known as the " Pineapple Express" in a nod to the storm's fuel source due to its Hawaiian origins, is set to bring significant moisture to California. This system has become what is known as a bomb cyclone. This animation shows the rapid strengthening of a low-pressure system as it approaches the West Coast.
