Wildfires in Southern California
After more than two weeks of wildfires, Southern California is finally receiving some much-needed rain as crews continue to battle the Palisades, Eaton, and more recent Hughes fires.
Current Situation
The rainy weather is expected to start on Saturday afternoon and continue through Monday. Sunday is anticipated to bring the most intense rainfall of the three days.
Rainfall Expectations
Much of the Los Angeles area should expect 0.5 to 1 inch of rainfall, and 1 to 2.5 inches surrounding the San Gabriel Valley foothills, according to NBCLA meteorologist Belen De Leon. Rainfall rates will be on the lighter side with peak rates generally between 0.1 to 0.25 inches per hour.
Rainfall Intensity
The probability of rain exceeding 0.5 inches per hour, which is more likely to trigger debris flows, is low. However, a flood watch was issued from Sunday afternoon through Monday afternoon for the burns scar near Malibu and the LA County coast.
Charred Hillsides
Charred hillsides stripped of vegetation do not absorb water well, creating the potential for flash floods and mudslides that can collect debris and wipe out structures in their paths. The extent of a mudflow will depend on the intensity of the rainfall, duration of the storm, and the amount of remaining vegetation to hold everything in place.
Emergency Precautions
The City of Los Angeles issued an emergency order Tuesday morning in anticipation of possible rain in neighborhoods damaged by wildfires. Gov. Gavin Newsom also issued a similar order Monday. Los Angeles city leaders advise residents to prepare their home and stay alert for possible evacuation orders should new fires or heavy mudslides begin.
Impact on Weather
The rain will also bring colder weather with it. Highs will drop significantly with temperatures in the 50s and 60s, 10-15°F below normal, De Leon said. As the storm exits early next week, expect a sharp drop in temperatures that could lead to frost and freeze conditions, particularly in wind-sheltered areas.
Snowfall in the San Gabriel Mountains
Snowfall is expected throughout the San Gabriel Mountains upwards of 4,000 ft. Winter travel alerts have been posted in the area warning drivers of the poor conditions.
Conclusion
While the rain provides some relief for those affected by the wildfires, it also poses new challenges and risks. It is crucial for residents in and near fire zones to remain prepared and take necessary precautions to stay safe.
