The intensity of seismic tremor has increased significantly over the past 6 hours, and satellite data indicate that the ash cloud is now at an altitude of 25,000 ft above sea level. As of 11:00 am AKST (20:00 UTC) the cloud is moving towards the northwest and extends for about 125 miles (200 km) downwind.
Aviation users should refer to the National Weather Service for updated SIGMETs on the ash cloud hazard (http://aawu.arh.noaa.gov/sigmets.php). No reports of ash fallout on nearby communities have been reported, and we encourage observers to contact AVO should it occur (https://www.avo.alaska.edu/ashfall/ashreport.php).
