Volcano Update

It's a fairly normal Friday around here, but here's an update on Mt.Redoubt from the Alaska Volcano Observatory:

A large eruption of Redoubt volcano occurred at 09:24 AKDT (17:24 UTC) this morning. National Weather Service reports the cloud height to be at least 65,000 ft above sea level and pilot reports indicated a plume height of 60,000 ft. Since this event, a few smaller events have occurred but these did not generate plumes above about 20,000 feet.

The eruption at 9:24 AKDT also produced a lahar in the Drift River valley that was detected by seismic instruments.

An ashfall advisory is in effect until 4 PM for the western Kenai Peninsula. High level ash (above 30,000 feet) is forecast to pass over Anchorage, but is not expected to produce ash fall.
