A powerful storm system is approaching California, bringing with it the potential for “life-threatening flooding” and heavy snow, according to the National Weather Service. This weather event is expected to hit the state over the weekend and into early next week.
Impending Danger: Flooding and Heavy Snow
The combination of warm air from the Pacific, strong onshore flow, and cool air is likely to result in thunderstorms and rainfall rates of up to an inch per hour. Damaging winds, brief tornadoes, and waterspouts are also possible along the coasts and valleys of southwest California.
The entire state can expect heavy rainfall, with coastal and valley areas receiving 3 to 6 inches, and mountain ranges expecting 6 to 12 inches of rain. The National Weather Service has issued a High Risk of Excessive Rainfall for the Transverse Ranges of Southern California, with a longer duration event anticipated over the next 48 hours.
Potential Risks: Flooding and Debris Flows
With such significant rainfall, the area is at risk of experiencing life-threatening flash floods, river floods, and urban floods. There is also a potential for debris flows and mudslides. Communities living on or below hillsides, especially those affected by wildfires, are particularly vulnerable to these impacts, as highlighted by the California Governor’s Office of Emergency Services.
Safety Precautions and Evacuations
Residents are strongly advised to stay informed through local alerts and follow the guidance provided. It is crucial to avoid walking or driving through debris flows and seek higher ground in case of flooding. Mandatory evacuations have already been ordered for parts of Santa Barbara and Ventura counties.
To support affected residents, sandbags are available at multiple locations, and shelters will be opened for those in need. These measures aim to ensure the safety and well-being of everyone in the impacted areas.
Golf Tournament and Wind Gusts
The PGA Tour’s AT&T Pebble Beach Pro-Am, scheduled to be held in Pebble Beach along the coast, had to be delayed due to the heavy rain and strong winds. The storm system has the potential to cut short the tournament. Northern and Southern California may also experience damaging wind gusts of up to 95 mph, which could result in downed trees and power outages.
Heavy Snow in Mountainous Regions
Higher elevations, including the Sierra Nevada and Northern California mountain ranges, can expect heavy snowfall. Snow totals of several feet are forecasted for these areas, with snow rates of 2-3 inches per hour and strong winds leading to whiteout conditions and treacherous travel conditions. Elevations above 7,000 feet in Southern California may also witness heavy snowfall.
Continuing Impact
As the storm system moves northward and inland, it is expected to bring moderate to heavy snowfall to the regional mountain ranges of the Pacific Northwest, Great Basin, and Northern Rockies over the next few days, as stated by the weather service.
Stay safe and informed during this challenging weather event by following local authorities’ guidance and updates.
