Los Angeles Rains Bring Relief from Wildfires but Pose Landslide Risk
After months of drought, Los Angeles is experiencing heavy rainfall, aiding in wildfire suppression but also increasing the potential for landslides.
Rain and Wildfires
Rainfall began Sunday and intensified overnight. Forecasters predict up to 1.25 inches of rain in Los Angeles and Ventura counties, with up to 2 inches in the mountains. While beneficial for extinguishing active wildfires and preventing new ignitions, excessive rainfall poses risks to vulnerable hillsides.
Landslide Concerns
Burned areas, stripped of vegetation, are susceptible to landslides. As of Sunday afternoon, rainfall in LA County reached one-third of an inch per hour, with potential to rise to three-fourths of an inch per hour, a rate that could trigger mud and debris flows. Meteorologist Joe Sirard emphasizes the concern for recent burn areas.
Firefighting Progress
Firefighters continue to contain major wildfires in the region. The Palisades fire has been 87% contained, while the Eaton blaze has reached 98% containment. However, the combined fires have destroyed over 16,000 structures and resulted in 28 confirmed fatalities.
Flood Outlook
The heaviest rain is anticipated late Sunday afternoon, prompting the National Weather Service to issue a flood watch for burn areas in Los Angeles County until Monday afternoon. This may escalate to a flood warning if rainfall intensifies. Forecasters stress that the risk of severe debris flows depends on the rainfall rate.
Conclusion
While the rainfall provides relief from wildfires, it also highlights the potential for landslides. Authorities monitor rainfall intensity closely and urge residents to remain cautious in vulnerable areas. The ongoing firefighting efforts and flood preparedness measures are crucial to mitigating risks and ensuring safety during this weather event.
