This weekend, California and Oregon are facing a significant flooding threat due to an atmospheric river hitting the region. The National Weather Service (NWS) has warned that the potential for flooding in both states is high, with saturated soils, high river levels, and rainfall totals of up to 7 inches. The West Coast has been experiencing harsh weather conditions, with widespread rain and rough seas. Portions of Northern California and southern Oregon are currently under gale warnings, high surf warnings, and hazardous seas warnings.
An atmospheric river is a narrow region that carries the most moisture outside of the tropics, according to the National Oceanic and Atmospheric Administration. NWS meteorologist Rich Otto explained that this is the season for atmospheric river events to occur, with the event expected to start on Friday evening, potentially dip in intensity on Saturday during the day, and then pick back up on Saturday night. There is a concern for areas with burn scars as heavy rain could lead to flash floods or debris flows. Northern California is under a flood watch this weekend, with an increased risk of rock and landslides along roadways in affected areas.
The frequency of these atmospheric river events occurring in the region is considered somewhat unusual by meteorologist Rich Otto. He stated that the West Coast has already experienced significant rainfall from previous atmospheric river events. WeatherNation reported on California’s recent weather, noting ongoing massive waves off the coast around Fort Bragg and the persistent moisture from the atmospheric river bringing valley rainfall and mountain snowfall inland. The NWS has warned residents and beachgoers of 30- to 40-foot waves, with some reaching up to 60 feet at favored spots.
After the rain intensifies on Saturday night, the atmospheric river event is expected to come to an end on Sunday night, but only temporarily. It is crucial for residents in California and Oregon to stay informed about the changing weather conditions and potential flooding risks. The NWS continues to monitor the situation and issue warnings to help people prepare for and stay safe during this challenging weather event. It is important for individuals in at-risk areas to heed warnings, be prepared for flooding, landslides, and other hazards, and follow safety guidelines to protect themselves and their property during this severe weather event.
