The San Diego River is facing an imminent flood threat as water levels continue to rise, exacerbated by 2 to 3 inches of rain that fell this morning. Crossing roads over the river are becoming increasingly dangerous due to high flows, prompting authorities to issue warnings to residents in the affected areas.
Widespread and heavier rainfall is expected to persist in southwestern California throughout the morning and into the afternoon, with showers continuing into the evening. Meteorologists are also cautioning about a slight chance of thunderstorms during this period. The situation is expected to extend into tonight, with a gradual decrease in showers from north to south on Tuesday. However, mountainous regions are likely to experience continued rainfall on Tuesday.
As the weather system evolves, the snow level is predicted to rise to 7500 to 8000 feet by early afternoon, followed by a decrease to around 6500 feet later tonight.
Rainfall estimates vary across the region, with approximately one inch expected near the coast, 2 inches in the mountains, and around one-half inch in the deserts. There is a high probability, ranging from 85 to 90 percent, of receiving 2 inches or more of rainfall in certain mountainous areas, and a 60 percent chance for 3 inches or more in the wettest locations.
