Another torrential rainstorm hits California just days after an earlier storm caused severe flooding across the Golden State.
A significant storm will rapidly intensify over the Pacific Ocean en route to California Wednesday through Thursday, AccuWeather forecast. Because of the storm’s rapid development, it has been categorized as a “bomb cyclone,” a slang term for explosive cyclogenesis, the process by which storms outside of tropical regions reach cyclonic strength in a short period of time. The storm is expected to bring more flooding, power outages and high winds to a state already ravaged by severe weather.
During the New Year’s weekend, various parts of California experienced significant rainfall, including heavy rain, snow and wind. As a result, flooding was reported in certain regions, with photos and video of submerged cars emerging from San Francisco on Saturday afternoon.
The city saw 5.46 inches of rain, the second wettest day on record, according to John Shrable, a meteorologist for local news station KRON 4.
Like this storm, the new storm forecast coming this week is an “atmospheric flow,” in which a plume of precipitation originates from a tropical region that resembles a river on weather maps. The storm, now heading toward California, originated about 2,500 miles away in Hawaii. Such storms, originating in the Aloha States, have been dubbed “Pineapple Expresses” by observers.
AccuWeather lead meteorologist Brett Anderson predicted the storm’s path would first target northern California on Wednesday and move through central and southern California by Thursday. Some areas could see up to two inches of rain per hour, he added.
In his own statement on the forecast, Jon Porter, AccuWeather’s chief meteorologist, warned that flooding could cause road or highway closures, particularly in certain regions still grappling with the effects of the previous storm. He also warned of certain disruptions that could continue for several days after the storm, such as mudslides.
“There is a significant risk of flash flooding and people should be aware of and avoid rapidly rising water, which can quickly become life-threatening,” Porter said. “This will be a dangerous and powerful storm for California that can create life-threatening conditions and significant disruption that can last for several days. Not only will this storm be intense and tap into significant atmospheric flux, but arriving just days after the previous storm brought heavy rains and caused significant flooding, the impacts and risks that may arise are amplified.
