1-minute @noaa.gov #GOES18/#GOESWest True Color RGB images showed a hazy plume of resuspended volcanic ash (*from the 1912 eruption of Novarupta-Katmai*) as it was being transported across the Shelikof Strait toward Kodiak Island: geosphere.ssec.wisc.edu#playing:true...; #AKwx

One RAWS site near the coast had wind gusts to 50 mph.

Good catch -- strong katabatic offshore flow, driven by the surface temperate gradient between -40s to -50s F inland and around +20 F along the coast. #AKwx

The summit of #Kilauea exhibited a very robust thermal signature in #GOES18/#GOESWest Shortwave Infrared imagery -- which was briefly masked by the dense volcanic cloud.

Impressive eruption of #Kilauea today, with a rare triple fountain event -- with @noaa.gov #GOES18/#GOESWest showing a combination of SO2 and SO2+ash clouds. #HIwx

A moose in Hughes AK saw Denali's shadow today -- winter begins in 16 days. #AKwx

Next step is to freeze the Madison area lakes -- lows around 0F on Thursday and Friday mornings just might do it.

Air Mass RGB images from @noaa.gov #GOES18/#GOESWest showed the leading edge of the SO2-rich #HayliGubbi volcanic cloud (brighter shades of magenta) as it moved eastward across the North Pacific Ocean (east of Japan).
