Guidance for air quality alerts: Insights from the NWS

When an air quality alert is in effect, following the NWS guidance is pivotal. Here are some simple tips from the NWS for safeguarding your well-being:

Retreat indoors whenever feasible:

If it’s within your means, stay indoors, especially if you have respiratory issues, health concerns, or fall within the senior or child demographics.

Trim outdoor activities:

When you can’t avoid going outdoors, keep outdoor activities to the bare essentials. Reducing your time outdoors is the key.

Cut back on pollution-inducing activities:

Exercise prudence when it comes to activities that exacerbate pollution, such as driving cars, wielding gas-powered lawnmowers, or utilizing other motorized vehicles. Minimize their use during air quality alerts.

No open burning:

Resist the urge to burn debris or any other materials during an air quality alert. This practice only adds to the air pollution problem.

Stay well-informed:

Keep yourself well-informed by tuning in to NOAA Weather Radio or your preferred weather news outlet. Staying in the loop empowers you to make informed decisions regarding outdoor engagements during air quality alerts.

Focus on respiratory health:

If you have respiratory issues or health problems, exercise extra caution. These conditions can make you more vulnerable to the adverse effects of poor air quality.

By adhering to the advice from the NWS, you can enhance your safety during air quality alerts while reducing your exposure to potentially harmful pollutants. Stay aware, stay protected, and make your health a top priority.
