Wildfire smoke
PM2.5 is forecast to reach 37 µg/m³ in the next 24 hours while NASA satellites detected 181 fire hotspots within 300 km in the last day (nearest about 25 km away). Smoke is a likely contributor: keep windows closed, run an air purifier or HVAC filter, and check the fire map before heading out.
