THROUGH 1500Z May 4, 2025
SMOKE: Western United States... A thin, elongated layer of light density smoke was observed this morning, extending over Northern California, central Oregon, and central Washington. Central Canada/Central and Southern United States... An area of remnant to light smoke from fires in western United States and western/southern Canada was observed moving eastward across Saskatchewan, Manitoba, and parts of Ontario. The smoke extended south through the U.S Mid-West and central Plains, and settling as far south as Oklahoma and Arkansas. The smoke also mingled with smoke in Texas that was produced from separate fire activity in Mexico. Northern-Central Mexico/Central-Southern Texas... A large area of light smoke covered extended from Northern Mexico to Texas from widespread fire activity across most of Mexico. The smoke overlapped towards central and southern Mexico with the combination of mixed aerosols and smoke mentioned below. AEROSOL/SMOKE: Central and Southern Mexico/Gulf of America/Bay of Campeche/Pacific Ocean... An area of light density smoke/aerosol attributed to widespread seasonal fire activity, volcanic emissions, and industrial sources throughout Central and Southern Mexico was observed over the coastline of Southern Mexico continuing to move west further into the Pacific, and north into the Bay of Campeche, Gulf of America and southern US. Nguyen THIS TEXT PRODUCT IS PRIMARILY INTENDED TO DESCRIBE SIGNIFICANT AREAS OF SMOKE ASSOCIATED WITH ACTIVE FIRES AND SMOKE WHICH HAS BECOME DETACHED FROM THE FIRES AND DRIFTED SOME DISTANCE AWAY FROM THE SOURCE FIRE, TYPICALLY OVER THE COURSE OF ONE OR MORE DAYS.
