Southern California Expected to Receive Much-Needed Rain
Southern California is preparing for another chilly and wet day, with rainfall expected to bring much-needed moisture after a notably dry beginning to the winter season. Meteorologist Bryan Lewis from the National Weather Service in Oxnard has provided insights into the upcoming weather patterns.
Weather Forecast and Rainfall Projections
On Thursday, precipitation is expected to range from a tenth to a quarter of an inch along coastal regions, while mountainous and foothill areas may witness higher totals. This storm system is projected to exit the region by Friday, leading to a dry weekend where temperatures are anticipated to reach the high 60s to low 70s.
Looking ahead, Southern California will likely encounter two additional storms next week, with predictions indicating they could be stronger than the current one. According to Lewis, the rain totals for these storms are still uncertain, but forecasts include:
- A 40% chance of moderate rain levels between 1 and 2 inches.
- A 30% possibility for rain accumulation between 2 and 4 inches.
- A further 30% chance for precipitation under one inch.
Current Rain Totals and Conditions
As of Thursday morning, selected areas have recorded significant rainfall. Crystal Lake in the San Gabriel Mountains received 1.18 inches, while Camp 9 saw 1.14 inches. Coastal stations, however, reported lesser amounts; Los Angeles International Airport measured just under half an inch and Long Beach recorded 0.29 inches.
Despite these rainfalls, the region is still falling short of typical seasonal averages. Since the water year commenced on October 1, downtown Los Angeles has accumulated only 6.11 inches, well below the average of 11.27 inches for this time, with the yearly norm being 14.25 inches.
Benefits of Rainfall for Local Vegetation
The freshly fallen rain has positively impacted local ecosystems, particularly beneficial for vegetation that has struggled due to extreme summer heat and a dryer-than-usual winter. Lewis commented, “These rains certainly help… it’s still kind of dampening the fuels and hopefully giving us enough moisture to stay clear of the fire season for longer.”
Mountain Conditions and Wind Warnings
Along with rain, this storm has enhanced snowfall in California’s mountain ranges. However, the National Weather Service has issued wind warnings indicating widespread gusts of 40 to 55 mph across mountainous and desert areas. Boaters are advised to exercise caution, as wind conditions may reach gale force.
Preparedness in Burn Zones
In anticipation of the storms, Los Angeles County officials have prepared for potential impacts in burn areas, especially at the Palisades and Eaton fire scars, which pose a heightened risk of debris flows. While rain from this storm is not expected to trigger significant mudslides, experts warn that rainfall rates exceeding half an inch per hour can increase the risk of such events.
In the current system, peak rainfall rates may reach between a tenth to a third of an inch per hour, while localized areas could experience half an inch per hour.
Conclusion
As Southern California braces for more storms in the coming days, the moisture from this week’s rainfall is expected to provide relief to dry conditions, setting the stage for a more balanced water year ahead.
