| Central Maryland is preparing for a multi‑day period of degraded air quality and above‑normal heat beginning Thursday and continuing through Friday, with conditions possibly persisting into Saturday. Residents along the I‑95 corridor and in northeast Maryland should take precautions as wildfire smoke, ozone pollution, and elevated temperatures converge to create hazardous conditions.
Wildfire Smoke Moving South Thursday Morning
A wave of wildfire smoke is expected to push southward into central Maryland Thursday morning under a lee trough. As the smoke settles, fine particulate matter (PM2.5) will increase, leading to USG (Unhealthy for Sensitive Groups) air quality conditions.
The highest concentrations are anticipated in northeast Maryland, where smoke will arrive first and linger the longest before gradually dispersing.
Ozone Pollution Adds to Air Quality Concerns:
In addition to smoke, ground‑level ozone is expected to rise during the afternoon hours Thursday and Friday. Combined with elevated particulate levels, this will create challenging conditions for individuals with asthma, heart disease, or other respiratory concerns.
Heat Safety During Above‑Normal Temperatures:
Temperatures will remain above seasonal averages, increasing the risk of heat‑related illness—especially when combined with poor air quality. Residents are urged to:
-Drink plenty of water, even if you don’t feel thirsty.
-Limit outdoor activities between 10 a.m. and 4 p.m., when heat and ozone levels peak.
-Wear lightweight, light‑colored clothing to stay cool.
-Take frequent breaks in air‑conditioned buildings or shaded areas.
Air Quality Precautions:
-Sensitive groups—including children, older adults, and individuals with chronic heart or lung conditions—should take extra care:
-Reduce outdoor exertion.
-Keep windows closed and use air conditioning or HEPA filtration if available.
-Avoid activities that stir up indoor dust, such as vacuuming without a HEPA filter.
Protecting Vulnerable Community Members:
Officials remind residents never to leave children, older adults, or pets in a parked vehicle, even for a short time.
Community members are encouraged to check on neighbors, friends, and family who may be more vulnerable to heat or poor air quality.
