Spatter-fed lava flows emanate from the summit vent on occasion. Mudflows and some flooding in the Cathedral River valley north of the volcano may occur. Airborne ash hazards to aircraft may be considerable if a large explosive event occurs but are much less severe during a typical Strombolian phase.

Clouds continue to obscure the volcano.
Satellite imagery in the past 24 hours has not detected any significant ash plume which is consistent with intermittent, low-level Strombolian activity.
