Air quality alerts: Recommendations 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:

Seek shelter indoors when possible:

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 venturing outside becomes unavoidable, limit your outdoor exposure strictly to essential tasks. Reducing your time outdoors is the name of the game.

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.

No open burning:

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

Stay 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.

Respiratory health matters:

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.
