A series of powerful storms is set to hit Southern California, bringing heavy rains, snow, and hazardous conditions across the region. Forecasts predict 1 to 3 inches of rain along with the first major storm in weeks, which could lead to flooding and unsafe road conditions. Residents are advised to be cautious as flash flood warnings have been issued, particularly in burn scar areas. The storm system is anticipated to create wintry conditions in the mountains, with snowfall expected as snow levels drop. Following a warm streak, cooler temperatures and intense rain are on the horizon, prompting the National Weather Service to prepare for a busy weather week ahead. Road users should stay informed and consider registering for storm reporting programs to aid in monitoring conditions.
