Great Sitkin (ORANGE/WATCH): Steaming and weakly elevated surface temperatures observed in partly cloudy satellite views. A clear webcam look from GSIG shows no lofted steam plume.

Shishaldin (YELLOW/ADVISORY): SO2 emissions visible in the noise in TROPOMI. Plume emissions observed in satellite, webcams. A little cloud overnight left one possible very weakly elevated surface temperature look.

Atka volcanic complex (GREEN/NORMAL): Typical weakly elevated temperatures from the warm lake in clear overnight views. Daytime Planet imagery shows weak steaming from the lake. No deposits or plumes from any tremor-related activity in any data. Webcam is out.
