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 to essentials:

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

Mitigate pollution sources:

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.

A ban on open burning:

Resist the urge to burn debris or any other materials during an air quality alert. This practice only adds to the air pollution problem.

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 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.

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.
