The Aviation Color Code remains at RED and the Alert Level remains at WARNING, reports AVO.

An observer on Unalaska Island reported seeing a large white-gray mushroom cloud form over Bogoslof, with ash fall out to the west. Winds in the area are currently to the northwest.

Since the explosion, seismicity and infrasound as detected on neighboring islands is quiet, no lightning has been detected, and satellite images show no additional emission from the volcano.

The National Weather Service Alaska Aviation Weather Unit has issued a SIGMET for possible ash to 50,000 ft asl.

The NWS has a Marine Weather Statement for trace or dusting of ash over coastal waters near the island.

Bogoslof volcano remains at a heightened state of unrest and in an unpredictable condition. Additional explosions producing high-altitude volcanic clouds can occur at any time. Low-level explosive activity that is below our ability to detect in our data sources may be occurring. These low-level explosions could pose a hazard in the immediate vicinity of the volcano.
