California Braces for Intense Atmospheric River: Potential Flooding and Power Outages

Rare High Risk of Flooding

California is on high alert as an intense and long-lasting atmospheric river descends upon the state, posing a rare Level 4 risk of excessive rainfall. This risk extends to Los Angeles, Santa Barbara, and Oxnard, with warnings of 'life-threatening flash flooding.' Rainfall rates could reach up to an inch per hour, resulting in 3 to 6 inches of rain across the region. Coastal California, including San Francisco, faces a widespread Level 3 risk of flooding.

Residents, with the help of lifeguards, collect bags of sand in preparation for the storm in Long Beach, California, on Saturday.

The forecast for Los Angeles predicts the possibility of a month's worth of rain in just a few days. With estimates of 3 to 6 inches of rainfall, residents are advised to take necessary precautions as the storm approaches. Authorities are emphasizing the importance of preparedness and vigilance in the face of this impending natural disaster.

Evacuation Orders and Emergency Measures

In anticipation of the severe weather conditions, mandatory evacuation orders have been issued for communities in Santa Barbara, San José, and Ventura County. Residents are urged to heed these orders to avoid the potential 'life-threatening' floods and landslides that may result from the atmospheric event. In Santa Barbara County, several school districts have already canceled classes in response to the anticipated severe weather conditions.

The National Weather Service in San Francisco issued its first-ever hurricane force wind warning, highlighting the unprecedented nature of the impending storm. Wind advisories and high wind warnings are in effect for millions of residents across inland areas of the state, spanning from Redding to San Diego. Travel disruptions are expected, particularly in mountainous regions where snowfall and dangerous wind gusts will create hazardous conditions for motorists.

Preparations and Safety Measures

As California braces for flooded roadways and swollen rivers, the state is mobilizing resources to respond to potential emergencies. The atmospheric river, characterized by its long, narrow moisture band, is anticipated to linger over the region, leading to prolonged rainfall and increased risks of flooding. The storm's impact is expected to peak between Sunday and Tuesday, with central and southern coastal areas facing the greatest threats.

Authorities are urging residents to prepare for potential power outages by securing alternative power sources and avoiding non-essential travel during the storm's peak. The looming danger of downed trees, power outages, and flooding has prompted a state-wide deployment of over 8,500 personnel, including swift water and helicopter rescue teams. Californians are advised to stay informed, stay safe, and assist vulnerable members of their communities during this critical time.
