Pineapple Express Storms Sweep Through California, Breaking Records
The first of two powerful “Pineapple Express” storms arrived in Southern California early Wednesday following a severe impact on Northern California. The storm led to record rainfall, river swelling, landslides, and evacuations in some areas.
In Forestville, Sonoma County, a house collapsed into the Russian River due to a rain-soaked hillside giving way. Downstream areas of the river, including Guerneville, remain under evacuation orders due to the flooding risk until Thursday morning.
While the first storm weakened as it moved south, another strong atmospheric river is set to hit Southern California on Thursday. Forecasters predict minor impacts, like increased traffic collisions, with relatively light rainfall similar to Tuesday night and Wednesday morning.
Looking ahead, a potentially stronger storm is on the horizon for next week, raising concerns for continued rainy weather through mid-February. Meteorologist Ryan Kittell from the National Weather Service warns against complacency, emphasizing the need to remain vigilant as more storms are expected throughout the winter.
Future Rainfall Possibilities in California
Between February 12 and 15, a range of rainfall possibilities exists with a 20% chance of high rain amounts, a 50% chance of moderate amounts, and a 20% chance of low rain. Forecasters have noted an increased possibility of heavier rainfall, urging residents to stay informed and prepared.
The upcoming storm might arrive as early as February 11 evening or as late as Valentine’s Day afternoon. The estimated duration and intensity of the rainfall remain uncertain, varying from steady rain lasting several hours to potentially lasting up to two days.
In Los Angeles County, the news of light rain this week comes as a relief following a month of devastating wildfires, which claimed lives and destroyed numerous properties. However, despite the rainfall reducing wildfire risks, the region’s dry winter poses ongoing fire hazards.
Post-Storm Concerns in Southern California
As the first storm subsides, concerns arise over potential landslides and mudflows in recent burn areas, prompting precautions and temporary road closures in high-risk zones. L.A. County officials emphasize the cumulative impact of rains on already unstable terrain and infrastructure from recent wildfires.
The ongoing assessment of damage from January’s fires highlights the extensive impact on communities in rebuilding efforts. Hazardous debris clearing by the Environmental Protection Agency is underway, aiming to address environmental risks in fire-ravaged areas and ensure safety for residents and commuters.
Continued Weather Outlook
With the anticipation of a second storm, Southern California prepares for additional rain and potential risks of flooding and debris flows in affected areas. The forecast suggests milder rainfall totals compared to the previous storm, providing relief from prolonged wet weather for some counties.
Northern California continues to experience heavy rainfall and strong winds, resulting in record-breaking precipitation and ongoing river swelling. Amidst the back-to-back storms, fresh snowfall blankets the northern mountain ranges, promising significant snow accumulation up to several feet in higher elevations.
Conclusion
As California braves through a series of impactful storms, residents and authorities stay vigilant, monitoring the evolving weather patterns and their subsequent effects on the region. Preparedness, caution, and adherence to safety guidelines remain crucial during this period of increased rainfall and potential natural hazards.
