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:

Retreat indoors whenever feasible:

If you can, take refuge indoors, especially if you have respiratory concerns, underlying health conditions, or belong to the senior or child demographics.

Trim outdoor activities to essentials:

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

Cut back on pollution-inducing activities:

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.

A no to 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 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.

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.
