The National Weather Service issued a wind advisory on Sunday at 12:55 p.m. For the 5 Freeway north of Los Angeles and several surrounding mountain regions. The advisory is in effect for Monday, May 18, between 3 a.m. And 3 p.m.
Expected Conditions and Affected Areas
According to the NWS Los Angeles/Oxnard CA, “Northeast winds 20 to 30 mph with gusts 40 to 50 mph expected.” These conditions may create hazardous environments for motorists and residents.
The advisory covers a wide range of locations, including the 5 Freeway corridor near Santa Clarita and the Santa Susana Mountains. It also extends to the Northern and Southern Ventura County Mountains, the Eastern San Gabriel Mountains, and the Western San Gabriel Mountains/Highway 14 Corridor.
Potential Risks and Safety Implications
The NWS warned that “gusty winds will blow around unsecured objects,” and that tree limbs could be blown down. These events may result in a few power outages across the affected regions.
Travelers are urged to use extra caution, as the NWS stated that “winds this strong can make driving tough, especially for high profile vehicles.”
Understanding NWS Wind Alerts
The NWS utilizes three distinct categories to communicate risk. A High wind watch means sustained, strong winds are possible, and residents should be prepared by securing loose items.
A Wind advisory, like the current one, indicates that strong winds are occurring but are not severe enough to warrant a warning. In this stage, the public is advised to take action by securing outdoor objects and exercising caution while driving.
A High wind warning is the most severe level, indicating that strong winds and gusts are currently happening. During a warning, individuals should seek shelter immediately.
Preparation and Response Guidelines
To prepare for approaching winds, the NWS suggests trimming tree branches away from power lines and homes, as well as securing loose shutters and gutters. Residents in mobile homes should identify a sturdy building to relocate to if a warning is issued.
Other recommended preparations include charging the batteries of cell phones, booster packs, weather radios, and power tools, such as reciprocating saws, which may be necessary to clear debris.
Actions During and After the Event
If caught outside or driving, individuals should seek shelter in a sturdy building. If no building is available, a car may serve as shelter, provided it is moved away from power lines or trees that could fall.
Drivers are advised to gradual down and keep both hands on the steering wheel. It is important to avoid trees, power lines, and the side of the road, keeping in mind that downed power lines may be live.
Once winds subside, the public is cautioned to stay away from downed power lines and report them to the police. Care should also be taken when handling debris that may have blown into yards.
