Overview

• USGS and the National Weather Service say the volcano remains at background activity with Alert Level NORMAL and Aviation Color Code GREEN.
• Strong easterly–southeasterly winds lifted decades-old material from the crater and slopes, a phenomenon observed during dry, snow-free conditions.
• Pilot reports and satellite and webcam imagery indicated ash rose to roughly 10,000 feet near the mountain.
• Authorities warn the resuspended particles are hazardous to aircraft and can affect air quality, though they do not signal renewed volcanic activity.
• Ash seen in Greater Victoria was assessed by Canadian officials and USGS as wildfire residue from the Bear Gulch area rather than volcanic fallout.
