California Dust Storm Chokes Air Quality

Fine particle pollution has reached "unhealthy" and "very unhealthy" levels across parts of southern and southeastern California. The National Weather Service issued an air quality alert due to strong westerly winds of 25-35 mph, with gusts up to 60 mph, forecast through Sunday morning. These windblown dust particles are fine enough to be inhaled deep into the lungs, potentially causing chest tightness, shortness of breath, and coughing.

Visibility is also expected to be reduced by the blowing dust. The Coachella and Imperial Valleys are identified as the most impacted areas. During these unhealthy air conditions, everyone is advised to limit outdoor activity, with sensitive groups strongly recommended to avoid it entirely.

Residents are encouraged to reduce vehicle emissions by carpooling or using public transport. Indoors, closing windows and doors, using air purifiers, and avoiding indoor pollutant sources like candles or incense are recommended. Swamp coolers and gasoline-powered lawn equipment should also be avoided as they can draw in or create more polluted air.

The air quality alert for the Coachella Valley is expected to lift by mid-Sunday morning as winds subside, while the Imperial Valley warning continues until Sunday evening. Strongest winds may persist into Monday, with lighter winds expected from Tuesday onwards, leading to improved air quality.
