High winds and drier weather will bring elevated to critical fire weather and potential power outages in much of Southern California, and elevated fire risk in Northern California’s interior, Thursday and Friday, according to the National Weather Service.
The California Governor’s Office of Emergency Services (Cal OES) wants all Californians to be aware, prepare, and stay safe.
In California, where extreme weather events are common, wind can be a silent instigator of disasters.
Along with state and federal partners, Cal OES monitors wind speeds around the state to identify and mitigate risk factors that could start or expand wildfires.
To protect public safety, California’s investor-owned electric utilities may temporarily turn off power to specific areas to reduce the risk of fires caused by electric infrastructure. This is called a Public Safety Power Shutoff (PSPS).
Residents should contact their utility provider for the latest information on anticipated timing and duration of any potential power shutoffs.
Individuals who use medical equipment in their homes, may qualify for utility providers’ Medical Baseline Program. The program provides advanced notifications before a PSPS and helps offset costs of additional electricity required by medical equipment.
Wind’s Role in Disasters:
High winds are not just strong gusts of air; they can act as a catalyst, setting in motion a series of events that lead to disasters. Here’s why wind is a serious risk factor:
Wildfire Spread: When strong winds meet dry vegetation, they can carry embers for miles, igniting new fires in their path and rapidly expanding existing ones. This wind-driven wildfire phenomenon has been responsible for some of California’s most destructive blazes.
Power Outages: High winds can damage power lines and utility infrastructure, leading to widespread power outages. These outages can disrupt communication, healthcare, transportation, and daily life, especially when they coincide with other emergencies.
Structural Damage: High winds can wreak havoc on buildings and structures, causing roof damage, shattering windows, and even toppling trees onto homes and vehicles. The structural damage can lead to injuries and property loss.
Transportation Disruptions: Wind gusts can create hazardous conditions on the road, making it difficult for vehicles to maintain control. This can lead to accidents and road closures, further complicating evacuation efforts during emergencies.
Debris Propagation: High winds can turn everyday objects into projectiles, such as outdoor furniture, debris, and vegetation. These flying objects pose a significant threat to both people and property.
During a high wind event:
- Take cover next to a building or under shelter.
- Stay clear of roadways and train tracks, a gust may blow you into danger.
- Use handrails when available on outdoor walkways.
- Avoid elevated areas such as roofs.
- Watch for flying debris, as street signs and tree limbs may become loose during strong winds.
If near downed power lines:
- Never go near downed power lines, since high voltage wires may still be active despite being downed.
- Avoid anything that may be touching downed power lines, including tree branches and vehicles.
- Report downed power lines by calling 911.
Driving during a high wind event:
- Keep both hands on the wheel and slow down to a safe driving speed.
- Stay a safe distance away from other vehicles as strong gusts may blow others into adjacent lanes.
- Turn on your headlights if needed in case of blowing dust, sand, snow or rain.
- Be cautious of strong winds suddenly moving your car.
- Stay clear of high-profile vehicles or when towing a trailer, as these are more likely to be affected by high winds.
- Watch for debris that may suddenly blow onto the roadway.
- If winds are severe enough to prevent safe driving, pull over and park away from any trees, power lines, or other tall obstacles that may fall onto your car.
Wind patterns can shift rapidly and unexpectedly, making it challenging for residents and emergency services to anticipate its course accurately. This unpredictability increases the urgency of preparedness and safety measures. By understanding the role wind plays in these scenarios, individuals and communities can better prepare and take proactive steps to mitigate its impact.
