The forecast process involves analyzing data from supercomputers generating ensemble forecasts, though early predictions may be uncertain. About seven days before the storm, models start aligning, increasing forecasters’ confidence. Closer to the event, higher-resolution models provide more accurate predictions.
For the recent storm, early projections hinted at Santa Barbara and Ventura counties being most affected, but adjustments revealed Los Angeles County would bear the brunt. Meteorologists also adjusted computer models, suspecting underpredictions, and their instincts proved correct. The final forecast accurately predicted 8 to 14 inches of rain in the mountains through Feb. 6.

The storm exceeded expectations, with downtown Los Angeles receiving 8.66 inches in four days, surpassing the annual average. Despite this, the forecast’s range effectively guided warnings about flooding and landslide risks, aiding storm preparedness. Warnings allowed residents to stockpile sandbags, and response teams were ready for swift-water rescues across Southern California.
The collaboration between meteorologists and officials highlights the importance of coordinated efforts to mitigate the impact of severe weather events. Learning from past misses, such as the unpreparedness in San Francisco in 2022, emphasizes the significance of accurate forecasting and effective communication to ensure public safety.
