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:

Prioritize indoor stay:

If possible, remain indoors, especially if you have respiratory issues, other health concerns, or fall within the senior or child demographics.

Trim outdoor activities:

When venturing outside is unavoidable, restrict your time outdoors solely to essential activities. Reducing exposure is paramount.

Tackle pollution sources:

Be mindful of activities that increase pollution, like driving cars, operating gas-powered lawnmowers, or using motorized vehicles. Limit their usage during air quality alerts.

No open burning:

Avoid burning debris or any other materials during air quality alerts. This contributes to worsened air quality.

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.

Respiratory health matters:

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.

Following the recommendations from the NWS helps bolster your safety during air quality alerts, minimizing your exposure to potentially harmful pollutants. Stay vigilant, stay protected, and make your health the top priority.
