Southern California is facing a wet and dangerous weekend, as a powerful storm system sweeps across the region.
Meteorologists are warning that this unusually strong weather system could bring heavy rainfall, fast-forming floods, mudslides, and serious travel challenges for residents.
With rainfall expected to intensify throughout Saturday, authorities are urging people to stay alert and limit unnecessary travel.
Storm Overview: What Southern California Can Expect
Intense Rainfall Across the Region
Weather experts relying on Doppler radar estimates predict that some locations may receive up to half an inch of rain in just 30 minutes. This sudden downpour raises the possibility of dangerous flash flooding, especially in vulnerable areas.
According to the National Weather Service (NWS), Saturday is expected to bring the most severe and widespread rainfall for much of the region. In their Friday night area forecast discussion, NWS officials emphasized that the system delivering precipitation is “unusually strong,” increasing concerns for local communities.

Officials added that regions experiencing the heaviest rain may endure major traffic delays, blocked routes, and rapid water accumulation on streets and freeways.
