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:

Prioritize indoor stay:

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:

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

Scale back pollution-inducing practices:

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.

A ban on open burning:

Refrain from kindling fires with debris or any other materials during an air quality alert. Such practices only contribute to heightened air pollution.

Stay well-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.

Prioritize respiratory health:

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.

By adhering to the recommendations from the NWS, you can enhance your safety during air quality alerts and reduce your exposure to potentially harmful pollutants. Stay vigilant, stay protected, and prioritize your health above all else.
