Summary
An EPA AirNow sensor a few blocks east of the Boyle Heights cold storage facility fire logged an AQI of 621 at 9 p.m. Monday, well above the 300 threshold for hazardous air.
By Tuesday, that same temporary monitor had fallen to 66, showing how sharply smoke exposure near the fire shifted with changing wind patterns.
Other nearby sensors showed much lower pollution: one just west of the fire stayed at 95 or below, while another about 3,600 feet east peaked at 171.
Doctors urged residents—especially people with underlying conditions—to track the AQI, stay indoors and avoid outdoor exercise even when smoke is not obvious.
