Los Angeles is preparing for a significant storm this weekend, with Mayor Karen Bass urging Southern California residents to stay vigilant and take necessary precautions. The city has been working urgently to anticipate the storm, which is expected to hit on Sunday, Monday, and possibly Tuesday.

Mayor’s Urgent Message

Mayor Bass emphasized the importance of preparedness, stating that the upcoming storm could be as strong as Tropical Storm Hilary in August. Residents were reassured that the city is actively working to be ready for any challenges the storm may bring. Common-sense precautions, such as staying home and off the roads starting Sunday, were highlighted.

Weather Outlook for the Week

Saturday, Feb. 3

On Saturday, residents can expect cool temperatures with some cloudiness, reaching a high of 60 degrees. The National Weather Service issued a High Surf Advisory, effective through the beginning of next week. Additionally, a winter storm watch is in effect for the eastern San Gabriel Mountains, with predictions of significant snowfall and gusty winds.

Sunday, Feb. 4

The powerful atmospheric river is expected to arrive on Sunday afternoon and evening, with a wind advisory starting at 6 a.m. and a flood watch at 12 p.m. Very heavy rain, thunderstorms, and potentially life-threatening flash flooding are top concerns for officials.

Expected Rainfall

This multi-day storm could bring three to six inches of rain in coastal and valley areas, and six to 12 inches in the mountains. The bulk of the downpour is anticipated in a 24- to 36-hour period between Sunday and Monday.

Monday, Feb. 5

Heavy storm conditions are expected to continue into Monday, with National Weather Service forecasters urging people to prepare for a major flooding event. Strong winds are predicted, ranging from 30 to 50 mph in some L.A. County areas, increasing to 60 to 90 mph in higher mountain areas and the 5 Freeway corridor.

Warning for Los Angeles River

The Los Angeles River is expected to fill quickly, becoming a dangerous place to be. Residents in the basin area should be evacuated well before the rain onset, and flooding is possible in poor-draining and urban areas.

Tuesday, Feb. 6 and Beyond

The wet weather pattern is expected to persist into Tuesday evening, with continued rain. Drier conditions are anticipated by Wednesday, but a chance of showers will linger, and snow levels could fall as low as 3,500 feet by Thursday.

Historical Context

The potential impact of the storm is reminiscent of historic events, such as the 1000-year floods of 1861-62, featuring eight weeks of atmospheric rivers.

Conclusion

Residents are urged to stay informed and take necessary precautions as Los Angeles faces the imminent threat of severe weather. The collaborative efforts of local authorities and residents will play a crucial role in minimizing the potential risks and ensuring the safety of the community.
