Pavlof: Color Code RED Alert Level WARNING
The eruption of Pavlof Volcano that began on November 12 has intensified and the Aviation Color Code was raised to RED and the Volcano Alert Level to WARNING earlier today.
The intensity of seismic tremor remains at high levels and pilot reports though 12:30 AKST (21:30 UTC) indicate that the ash cloud height has increased to 30,000 ft above sea level.
Satellite, pilot reports, and wind data show the ash cloud moving towards the northwest over the Bering Sea.
Ash cloud height and direction will vary significantly through an eruption and aviation users should refer to the National Weather Service for updated SIGMETs on the ash cloud hazard (http://aawu.arh.noaa.gov/sigmets.php).
