Air Quality Advisory #1- Yellow Level

Response

Monitor

Area

St Maarten and Territorial Waters

Event description

Air quality across St. Maarten is deteriorating due to increasing concentrations of fine airborne particles. Air quality levels are forecast to reach the “Unhealthy for Sensitive Groups” category from Thursday through Saturday. Individuals sensitive to air pollution, including those with respiratory or heart conditions, older adults, and children, may experience health effects. Potential impacts include increased risk of asthma attacks, coughing, shortness of breath, and worsening allergy symptoms. Hazy conditions may reduce visibility, affecting travel, outdoor activities, and marine operations.

Instructions

Children, older adults, and persons with allergies, respiratory or heart conditions should limit exposure to outdoor air and avoid prolonged outdoor activities, as elevated concentrations of airborne particles may worsen symptoms. Small craft operators should exercise caution and remain alert for reduced visibility that may affect navigation.
