Air quality alerts: Recommendations 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:

Prioritize indoor stay:

Whenever possible, seek refuge indoors, especially if you grapple with respiratory concerns, health issues, or belong to the senior or child demographic

Trim outdoor activities:

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

Reduce pollution contributors:

Be conscious of activities that contribute to pollution, such as driving cars, using gas-powered lawnmowers, or relying on motorized vehicles. Curtail their use during air quality alerts.

Banish open burning:

Refrain from kindling fires with debris or any other materials during an air quality alert. Such practices only contribute to heightened air pollution.

Stay well-informed:

Stay updated of developments by tuning in to NOAA Weather Radio or your preferred weather news source. Being well-informed empowers you to make informed decisions regarding outdoor pursuits during air quality alerts.

Respiratory health caution:

If you grapple with respiratory issues or underlying health problems, exercise added caution. These conditions can render you more susceptible to the adverse effects of compromised air quality.

By adhering to the recommendations from the NWS, you can enhance your safety during air quality alerts and reduce your exposure to potentially harmful pollutants. Stay vigilant, stay protected, and prioritize your health above all else.
