Southern California Flood Advisory: Key Insights for Arborists

Flood Advisory Impacting Southern California: What to Watch For

A flood advisory is currently in effect across parts of Southwest California, specifically impacting Orange, Riverside, and San Bernardino counties. As of February 16, 2026, at 11:59 AM PST, the advisory warns residents of expected minor flooding due to excessive rainfall. This advisory is scheduled to continue until 2:54 PM PST, making it crucial for residents, especially arborists and those involved in outdoor activities, to stay alert.

Why This Flood Advisory Matters for Arborists

For arborists and tree care professionals, understanding the implications of such weather advisories is essential. Excessive rainfall can weaken trees, increasing the risk of limb failures and uprooting. This sudden increase in soil moisture levels can lead to decreased stability for many trees, particularly those in low-lying or poorly drained areas. Places like Anaheim, Riverside, and San Bernardino are already experiencing waterlogged conditions, prompting a proactive approach to tree maintenance.

The Conditions and Their Expected Effects

The National Weather Service (NWS) indicated that Doppler radar showed up to 0.5 inches of rain had already fallen by 11:59 AM, suggesting more is on the way. The advisory highlights the potential for road flooding, which can hamper travel and increase the risk of accidents—a vital consideration for arborists who may need to move equipment or access tree sites. The recommendation remains clear: "Turn around, don't drown" when encountering flooded roads. Awareness of these conditions can help arborists plan their routes and avoid hazardous areas.

Preparing for Severe Weather: Best Practices

In light of the recent storms affecting Southern California, it's vital for arborists to have a plan in place. Monitor local weather updates regularly and consider rescheduling tree evaluations or removals until conditions improve. Ensure that your team is trained to recognize the signs of a hazardous situation, including the risks associated with saturated soil. Establishing clear communication channels can help keep teams safe during unpredictable weather scenarios.

Looking Ahead: What’s Next for Southern California?

Forecasts indicate that Southern California may continue to experience adverse weather conditions, including thunderstorms and more rain. Arborists should remain vigilant and be prepared to respond quickly to any tree damage resulting from these storms. Weather patterns may fluctuate, necessitating a readiness to adapt operations in response to changing conditions.

In conclusion, staying informed about weather advisories and understanding their implications are crucial steps for arborists. By preparing adequately and keeping an eye on environmental factors, you can ensure safety and maintain the health of our urban forests during this challenging weather period.
