Maryland Chokes on Wildfire Smoke: Code Purple Alert
17 Jul
Summary
- Maryland faces Code Purple air quality alert due to Canadian wildfire smoke.
- Air quality is 'very unhealthy' for everyone, urging outdoor avoidance.
- City and state officials issue serious health warnings and safety advice.

Baltimore and much of Maryland are experiencing a Code Purple Air Quality Alert on Friday, July 17, 2026, due to dense smoke from Canadian wildfires. This alert signifies 'very unhealthy' air quality for all individuals, necessitating a strong recommendation to remain indoors and limit outdoor exertion.
Previous days saw a Code Orange alert, primarily affecting vulnerable groups. However, the current 'code purple' extends the health risks to the entire population. Symptoms of poor air quality can include shortness of breath, coughing, and dizziness, with existing chronic conditions potentially aggravated.
State and city officials, including Governor Wes Moore and Mayor Brandon M. Scott, are emphasizing the severity of the situation. They are urging residents to stay inside, keep windows closed, and prioritize the well-being of family and neighbors. Baltimore has moved city employees to indoor assignments and suspended services like trash pickup.
The situation is expected to improve slightly as weekend storms approach. Saturday is also designated a First Alert Weather Day due to expected severe storms, which should help dissipate the heavy smoke concentrations. Officials in Annapolis have activated cooling centers and closed a local pool.
