Description: From Dixon and others, 2017: "High winds entrained and resuspended ash from Novarupta-Katmai 1912 on March 11, 2015, continuing into March 12, 2015. Alaska Airlines and Ravn Alaska cancelled flights into and out of Kodiak, due to high winds and ash. The ash was visible in satellite imagery, and strong winds were blowing from the Katmai area toward the southeast (fig. 7 [original text]). The National Weather Service Alaska Aviation Weather Unit (NWS AAWU) issued a Special Weather Statement.

"Four episodes of resuspended ash were observed during August through October. A multi-day ash resuspension event began on August 28, 2015, and continued through August 31, 2015. On August 30, the NWS issued a SIGnificant METeorological (SIGMET) information statement, and AVO mentioned the resuspended ash in its August 28 weekly update and issued a separate information statement on August 31. The ash was weakly visible in satellite imagery. Two ash resuspension events occurred in September-on

September23, with ash confined to altitudes less than 1,500 m (5,000ft) ASL, and another on September 29-30.

Residents of Kodiak reported a fall of fine ash on the night of September 29-30, mixed with sleet and snow. AVO issued information statements on both occasions. The final ash resuspension event of 2015 occurred on October 29-30, when strong winds in the Katmai area again entrained loose 1912 volcanic ash and carried it east over Shelikof Strait and Kodiak Island. AVO again issued an information statement regarding the event."
