Critical Fire Weather Conditions & Potentially Damaging Winds Late This Weekend.

The National Weather Service (NWS), and our Office of Emergency Services, are monitoring the development of critical fire weather conditions and potentially damaging winds over the North Bay Mountains and Valleys, East Bay Hills and Interior Valleys, Diablo Range, San Francisco Peninsula Coast, and the Santa Cruz Mountains from late ‪Saturday through Monday morning‬. 

The most critical period will be ‪from Saturday night through early Sunday morning‬ when the strongest winds will occur. Winds "ease" in valleys/coast late on Sunday and into Monday, but will remain strong in higher elevations.

Although our region is not due to be impacted, we wanted to make you aware and also take this opportunity to provide you with high wind safety tips. 

The safest place to be during high winds is indoors. Postpone outdoor activities if a wind advisory or high wind warning has been issued.        

If you are caught outside during high winds:        

Take cover next to a building or under a shelter.        

Stand clear of roadways or train tracks, as a gust may blow you into the path of an oncoming vehicle.        

Use handrails where available on outdoor walkways and avoid other elevated areas such as roofs without adequate railing.        

Watch for flying debris. Tree limbs may break and street signs may become loose during strong wind gusts. Keep an eye toward nearby balconies for loose objects that may fall.        

In the event of a downed power line:    
Report downed lines in Sunnyvale to Sunnyvale dispatch at 408-730-7180. Do not try to free lines or to remove debris yourself. NEVER approach a downed power line.         

Avoid anything that may be touching downed lines, including vehicles or tree branches. Puddles and even wet covered ground can conduct electricity in some cases. Warn others to stay away.        

If you see someone who has been shocked who may be in direct or indirect contact with a power line, do not try to touch them. You may become a second victim. Get medical attention as quickly as possible by calling 911.        

If a line falls on your car, stay inside the vehicle. Take care not to touch any of the metal frame of your vehicle. Honk your horn, roll down the window and warn anyone who may approach of the danger. Ask someone to call the police. Do not exit the car until help arrives, unless it catches on fire. To exit, open the door, but do not step out. Jump, without touching any of the metal portions of the car's exterior, to safe ground and get quickly away.        

If you are driving:        

Keep both hands on the wheel and slow down.        

Watch for objects blowing across the roadway and into your path.        

Keep a safe distance from cars in adjacent lanes as strong gusts could push a car outside its lane of travel.        

Take extra care in a high-profile vehicle such as a truck, van, SUV, or when towing a trailer, as these are more prone to be pushed or even flipped by high wind gusts.        

If winds are severe enough to prevent safe driving, get onto the shoulder of the road and stop, making sure you are away from trees or other tall objects that could fall onto your vehicle. Stay in the car and turn on the hazard lights until the wind subsides. 

Again, according to NWS, our region will not be impacted by high winds. However, these high wind safety tips are always good to go over so that you’re prepared if it ever does impact our region.
