(Note: Mt. Spurr is an active volcano roughly 78 miles west of Anchorage, across the Cook Inlet. Prevailing winds are WSW to ENE, so any ash tends to blow almost straight across the greater Anchorage area. Paul)
The observatory says that new magma has intruded into the Earth’s crust beneath the volcano, which indicates an eruption is likely — but not certain — within the next few weeks or months.
... “Those eruptions each lasted a few hours and produced ash clouds that were carried downwind for hundreds of miles and minor ashfall [up to about ¼ inch] on Southcentral Alaska communities,” Haney said.
... Alaska Volcano Observatory Scientist in Charge Matthew Haney says the most likely outcome is something similar to what occurred in 1953 and 1992.
“Those eruptions each lasted a few hours and produced ash clouds that were carried downwind for hundreds of miles and minor ashfall [up to about ¼ inch] on Southcentral Alaska communities,” Haney said.

Oh lovely... Stay safe!
We'll do what we're able to do: a) wrap the air filters on the cars & truck with pantyhose to help keep the silica glass beads out of the engine, b) change the oil every month, c) change the air filters every 30 days, d) drive slow so as not to raise dust clouds, and e) wear N95 respirator masks & laboratory goggles whenever we're outside. Dang it.
