SoCal Wind Kicks Up ‘Harmful’ Particles

SOUTHERN CALIFORNIA — Following blustery weather, officials urged swaths of Southland residents to avoid outdoor activity and keep their windows closed to protect against harmful air quality.

As winds picked up Sunday and Monday, experts warned that dust and particles from burned areas could cause health hazards, the National Weather Service said.

"Everyone can be affected," the agency said, noting that sensitive groups such as those with lung or heart disease, older adults, pregnant people, children and those who spend more time outdoors were especially at risk.

"Particle pollution can get deep into the lungs and cause serious health problems such as asthma attacks, heart and lung disease symptoms, and increased risk of lung infections," according to the NWS' Air Quality Alert.

Weather officials advised residents to monitor air quality levels and avoid outdoor activities when the Air Quality Index levels turn unhealthy.

Here's what residents can do to stay safe, according to the NWS:

• Keep windows and doors closed
• Run your air conditioner and/or an air purifier
• Do not use whole house fans or swamp coolers that bring in outside air if you have other methods to stay cool
• Avoid other sources of pollution such as fireplaces, candles, incense, grilling, and gasoline-powered lawn and garden equipment

Here's how the NWS says you can help minimize outdoor particle pollution levels:

• Carpool, telecommute, reduce trips, or take public transportation
• Slow down if driving on dirt roads
• Stabilize loose soils

The agency issued air-quality alerts in communities from Los Angeles to Imperial counties, where particle pollution reached "harmful" levels due to windblown dust.

The warnings were especially prevalent for those who live near the Palisades and Eaton burn zones in LA County. While the county's air quality advisory was lifted at 10 a.m., windy conditions were still present on Monday morning, with expected gusts of up to 25 mph.

Meanwhile, in parts of Riverside County, a wind advisory was set to expire at 10 p.m. as west winds 25 to 35 mph were expected with 55 mph gusts.

"Gusty winds will blow around unsecured objects. Tree limbs could be blown down and a few power outages may result. Visibility may be reduced in blowing dust," the NWS warned. Winds this strong can make driving difficult, especially for high-profile vehicles. Use extra caution."
