Redoubt Weekend Open Thread

I'll be "off the grid" for the weekend at a wedding, so I thought I'd leave this open for any Redoubt news Eruptions readers hear over the weekend. Feel free to leave comments about the developments up in Alaska.

Currently, AVO reports that seismicity is lower since the eruptions this morning. They indicate that eruptions will likely occur without warning from here on in.

There are also some new articles on how the eruption is affecting air travel, including cancellations of flights to/from Anchorage and increases in freight flights in and out of Sea-Tac (Seattle, WA) in response to the limited access to Anchorage's Ted Stevens Airport. Back on the ground, road workers in Alaska have to deal with removing ash from the roads as well.

See you Monday!

I'm not off the grid just yet, so I'll pass this along from AVO:

An explosive eruption of Redoubt volcano occurred at approximately 19:25 AKDT (03:25 UTC). National Weather Service reports the cloud height to be approximately 51,000 ft above sea level based on radar.

This comes after:

An explosive eruption of Redoubt volcano occurred at approximately 17:35 AKDT (1:35 UTC). National Weather Service reports the cloud height to be approximately 40,000 ft above sea level based on radar.

Here are a few more details from the AP.

Sorry, that is Erik with a k, not a c.

We received just a light dusting here in Anchorage Saturday evening following an eruption around 3:30 pm. There was a slight sulfur smell in the air. Overnight there were heavy winds which blew a lot of the ash around and created some interesting distributions of gray and white on the snow. No ash alerts now, as far as I know.
