Long threatenting Mount Redoubt erupted about 10:38 p.m. Sunday, then again at 11:02 p.m., and 12:14 a.m. today sending an ash cloud an estimated 50,000 feet into the air.
Winds were expected to carry the ash plume north toward the Susitna Valley, possibly missing Anchorage to the east, the National Weather Service said.
“It looks like (Anchorage) might dodge the bullet,” Alaska Volcano Observatory geophysicist Peter Cervelli said.
Observatory staffers notified Federal Aviation Adminiistration officials immediately followiing the eruption.
