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:

Retreat indoors whenever feasible:

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 to essentials:

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

Mitigate pollution sources:

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.

No open burning:

Refrain from igniting fires with debris or any other materials during air quality alerts. Such practices only contribute to the problem of poor air quality.

Stay informed:

Stay updated by tuning in to NOAA Weather Radio or your preferred weather news outlet. Staying informed helps you make wise choices regarding outdoor activities during air quality alerts.

Focus on respiratory health:

If you have respiratory problems or underlying health conditions, exercise extra caution. These conditions can increase your vulnerability to adverse effects from 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.
