Guidance for air quality alerts: Insights from the NWS

When an air quality alert pops up on the radar, deciphering its implications is crucial. These alerts, issued by the NWS, come with straightforward yet essential guidance to ensure your safety:

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.

Minimize outdoor exposure:

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 mindful of activities that exacerbate pollution, such as driving cars, operating gas-powered lawnmowers, or using other motorized vehicles. Limit 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 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.

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.

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.
