AVO reported that weakly elevated surface temperatures in Cleveland's summit crater were identified in satellite images during 7-9 February.
Minor steaming was noted on 8 February.
AVO noted that these observations were consistent with the presence of a lava dome that began extruding in the summit crater in late January.
The Aviation Color Code remained at Orange and the Volcano Alert Level remained at Watch.
