As California braces for yet another round of heavy rainfall, residents and authorities are preparing for potential flooding and other weather-related hazards. This upcoming storm is expected to be another powerful atmospheric river, originating from the Pacific Ocean. Meteorologists predict that Los Angeles could receive 5 to 6 inches of rain, while Santa Barbara may see up to 8 inches. The coastal mountains and hills could experience even higher amounts, possibly exceeding 10 inches. These anticipated conditions follow a previous storm that caused widespread floods across San Francisco and Southern California.
According to Marc Chenard, a senior branch forecaster with the US Weather Prediction Center, this upcoming storm is projected to be a significant event, lasting longer than the previous system. He also noted that the current wet period, coupled with the later time of year, will exacerbate the situation. Streams and rivers are already at capacity, and the ground is thoroughly saturated. Consequently, the risk of flooding and mudslides throughout central and southern California is considerably high. Additionally, strong winds accompanying the storm raise the possibility of power outages.
California has already experienced instances of severe flooding, with San Diego being heavily impacted last month, and the entire state facing flooding this week. The deluge is unrelenting, as Los Angeles International Airport reported 2.49 inches of rain on Thursday alone. The National Weather Service has observed the Los Angeles River near Wardlow Road rising approximately 2.7 feet since Thursday. Similarly, the Santa Clara River near Piru is projected to rise 2.27 feet by Monday. Both rivers, fortunately, are anticipated to remain below flood stage. Coastal areas of Orange County are also expected to face waves up to 10 feet high.
Meteorologist Marc Chenard emphasizes that stream flow across the state is already well above average, exacerbating the risk of flooding. The already saturated conditions serve as a dangerous foundation for the upcoming storm. Additionally, the Sierra Nevada region is expected to receive heavy snowfall at elevations above 5,000 feet for the next few days. Accumulations of up to 2 feet of snow are possible, with snowfall rates potentially reaching 1 to 2 inches per hour, warns the National Weather Service.
This powerful storm serves as a chilling reminder of the devastating atmospheric rivers that struck California a year ago. These prolonged plumes of moisture coming from the Pacific resulted in the loss of at least 22 lives and caused destructive damage amounting to $4.6 billion, according to the National Centers for Environmental Information. As a result, residents and authorities remain vigilant, taking steps to protect lives and property in anticipation of this impending storm.
