California Hit by Dangerous Winds, Gusts Up to 70 MPH Across State

California found itself in the grip of a powerful and widespread wind event, as dangerous gusts tore through the state from Friday, May 15, 2026, through the morning of Monday, May 18. Residents across a vast expanse, stretching from the tranquil Pacific coast all the way to the rugged Nevada border, braced for significant impacts as the National Weather Service issued a series of urgent high wind warnings and advisories.

The severe weather system brought wind speeds that, in some localized areas, were predicted to hit a staggering 70 miles per hour. This widespread atmospheric disturbance created hazardous conditions for travel, outdoor activities, and presented a risk to infrastructure across numerous counties. The NWS offices across the state worked to keep the public informed on the evolving situation, detailing specific threats for various regions.

The initial alerts began on Friday, May 15, when the NWS Los Angeles/Oxnard office issued a high wind warning shortly after noon. This warning, effective from Friday evening until Sunday morning, specifically targeted the Southern and Northern Ventura County Mountains and the Interstate 5 Corridor. Forecasters anticipated northwest winds ranging from 30 to 50 miles per hour, with gusts potentially reaching up to 60 miles per hour. The strongest of these winds were expected to manifest during the overnight hours, though wind speeds were noted to possibly dip below warning levels during daytime periods.

Later that same Friday, just before midnight, the NWS Las Vegas office released its own high wind warning. This advisory, valid from Sunday morning until Monday early morning, encompassed the Eastern Sierra Slopes of Inyo County, the White Mountains of Inyo County, Death Valley, and both Owens Valley South and North. Here, northwest winds of 25 to 35 miles per hour were forecast, accompanied by gusts between 50 and 60 miles per hour. Critically, there was a reported possibility of a few gusts in these areas even reaching the 70-mile-per-hour mark.

Adding to the Friday alerts, the NWS Hanford office updated its high wind warning, which remained in effect until Sunday night for the Mojave Desert Slopes. This region was expected to experience northwest winds of 35 to 45 miles per hour, with gusts potentially soaring up to 70 miles per hour. Reports indicated that the most intense gusts within Southern California were largely predicted to strike Friday night and Saturday. These areas included the Interstate 5 corridor, the northwestern Antelope Valley, and the Santa Ynez Mountains, where there was a 70% chance of gusts hitting between 40 and 55 miles per hour, and a 20% chance they could exceed 60 miles per hour. High surf advisories were also put into effect starting Friday afternoon, signaling rough coastal conditions.

As the weekend unfolded into Saturday, May 16, more warnings were issued, broadening the scope of affected regions. The NWS San Francisco office issued a wind advisory early Saturday morning, valid from Saturday morning until Sunday early morning. This advisory covered Coastal North Bay, including Point Reyes National Seashore, the San Francisco Peninsula Coast, Big Sur, and San Francisco County itself. Residents in these areas could expect northwest winds of 15 to 30 miles per hour, with gusts up to 45 miles per hour, and localized gusts potentially reaching 55 miles per hour.

Further inland, the NWS Sacramento office issued a wind advisory later on Saturday morning, effective from Saturday night until Sunday evening. This advisory spanned a vast area, including South-Central Shasta County (Redding Metro), the Northern Sacramento Valley in Tehama County, Central and Eastern Glenn County, Butte County below 1000 feet, Central and Eastern Colusa County, Sutter and Yuba counties below 1000 feet, Western Yolo County (including Capay Valley and Interstate 505), Central Yolo and Northeast Solano counties (including Woodland and Davis), Central Solano County (including Fairfield and Vacaville), Southwestern Solano County (including Vallejo), the Sacramento County Delta, and the San Joaquin County Delta. North winds of 20 to 30 miles per hour with gusts up to 50 miles per hour were anticipated across these diverse locations.

The NWS San Diego office also joined the chorus of warnings on Saturday morning, issuing a wind advisory that remained valid until Sunday night for the San Diego County Mountains. Isolated gusts in this mountainous terrain were expected to reach up to 65 miles per hour, particularly from Saturday afternoon. Beyond the wind concerns, a Red Flag Warning was additionally put in place for the Sacramento Valley and the Northern San Joaquin Valley. This critical warning, effective from Saturday morning to Monday evening, highlighted the perilous combination of gusty winds and severe fire weather conditions, significantly increasing the risk of wildfires. Along the Central Coast, gusts of 30 to 40 miles per hour were projected for both Saturday and Sunday, adding another layer of concern for coastal communities.

The National Weather Service repeatedly emphasized the potential dangers associated with these powerful winds. Warnings from the NWS San Francisco office, for instance, explicitly stated that the gusty conditions would likely cause unsecured objects to be blown around. They also cautioned that tree limbs could be brought down, potentially leading to power outages. Specific concerns for coastal areas included blowing and drifting sand on beaches and roadways. Drivers were urged to exercise extreme caution, particularly those operating high-profile vehicles, as the strong winds were expected to make driving exceptionally challenging. Similar advisories were echoed by the NWS Sacramento office, reinforcing the message about unsecured objects, falling tree limbs, possible power disruptions, and the difficulties high-profile vehicles would face on the roads. These warnings underscored the broad-reaching disruption the wind event was poised to cause.

This extensive series of warnings across California highlighted the significant impact such a widespread weather event can have on daily life, infrastructure, and public safety. From the risk of power outages disrupting homes and businesses to the increased danger of wildfires in already dry regions, the wind event presented a complex challenge for emergency services and residents alike. The sheer geographical scope, encompassing nearly the entire state, underscored the need for constant vigilance and adherence to safety guidelines issued by local authorities.

As the wind event began to subside by Monday morning, May 18, the full assessment of its effects would become clearer. Residents were encouraged to remain aware of their local conditions and any lingering advisories, particularly concerning potential fire hazards or clean-up efforts from downed branches and debris. The event served as a stark reminder of California's diverse and sometimes volatile weather patterns, necessitating preparedness from its communities.
