Redoubt has just been shifted from Warning/Red to Watch/Orange alert status. The Alaska Volcano Observatory announced this in a Volcanic Activity Notice issued at 13:35 local time (21:35 GMT). The full text can be found here.

The Volcanic Activity Notice explains that the AVO’s decision to lower the alert status is based on reduced seismicity over the past 36 hours. It also notes that ‘Current seismicity at Redoubt is at times suggestive of intermittent lava extrusion at the volcano’s summit’ but that ‘the existence of a new lava dome has not been confirmed because of poor weather’. Looking ahead, ‘episodes of dome growth followed by explosive dome destruction is a likely but by no means certain, near-term scenario. Cycles of dome growth and failure could occur for several months’.

The alert level will of course change to reflect what the volcano is up to at any given time. It’s almost certain that we’ll see Warning/Red again at Redoubt in the near future.
