The wind is gusting up to 50 mph. I arrived downstairs about 20 minutes ago to find the cover of my grill in one corner of the back deck and the grill in the other.

No snow yet, but the deck is about 2 inches deep in slush. Which of course means the roads are as well. My son is simply devastated that it's not snowing. They've been hyping it all week.

Further bulletins as events warrant.

Reading a bit about Tonga this morning. They are well and truly screwed.

The only communication cable was damaged and repairs won't start until February.

Relief can't be flown in because the airfield is covered in ash.

New Zealand just sent two supply ships with rations, water and desalination pumps but it's going to take them two days to get there.

Those folks are completely on their own until at least Thursday.
 
VOLCANIC GRAVITY WAVES OVER HAWAII: The eruption of an undersea volcano near Tonga on Jan. 15th was even bigger than anyone thought. It nearly touched the edge of space. Hours after a mushroom cloud burst out of the Pacific Ocean, cameras at the Gemini Observatory on Mauna Kea recorded red waves rippling over Hawaii:

These are gravity waves, a type of atmospheric disturbance excited by intense thunderstorms and volcanic eruptions. Many gravity waves scud through the low atmosphere. The ripples caught by Gemini's Cloudcam, however, are in the mesosphere 85 km high--the realm of meteors, sprites, and noctilucent clouds.

Photographer Steve Cullen spotted the waves in online footage. "I had a hunch that Gemini Cloudcams might detect gravity waves produced by the eruption of Hunga Tonga-Hunga Ha'apai. So, I just took a look and there they were!"

"The volcanic eruption happened at 04:15 UTC, and the gravity waves passed Hawaii 4.5 hours later," notes Cullen. "This corresponds to a speed of ~1100 kilometers per hour"--a good match to the speed of sound in the mesosphere.

The waves are red because of airglow, an aurora-like phenomenon caused by chemical reactions in the upper atmosphere. Airglow is usually too faint to see, but gravity waves from the volcano boosted the reaction rates. Red is a sign of OH. This neutral molecule (not to be confused with the OH- ion found in aqueous solutions) exists in a thin layer 85 km high and can produce a pure red light.​

See the waves below. They begin at about the 3 sec mark.

I saw a show about this a year or two ago and back then I remembered thinking it was going to be a tough row to hoe.


That article makes it seem nearly impossible. Everybody once again looking after nothing but their own self interest while the walls come crashing down around them. I think this paragraph towards the end pretty much sums it all up:

A longtime Waikiki real estate lawyer who didn’t want to be named because he isn’t authorized to speak about clients said he is concerned about an incompatibility between the interests of local community members, whose children and grandchildren will live on Oahu’s south shore for decades, and hotel owners, many of whom are short-term, mainland-based or international real estate or private equity firms. “These are people who are generally not going to hold the asset for more than 15 years, so they don’t need to necessarily think long-term,” he said. “My big concern is that one day the risk profile will become too high, and people will say, ‘I’m not going to invest in Waikiki anymore.’ When that happens, a lot of people will be left behind.”​
 
Britain is also having it's issues. it's just spread over many little areas.


(the first map-gif is astonishing)

There's another named Fairbourne.


Trying anything seems...

It would be hard to hold a conversation over the deafening sound of the snow machines preparing the Olympic venues northwest of Beijing. They are loud and they are everywhere, blowing snow across what will be this month's most-watched slopes.​
It is almost beautiful -- except that the venues are surrounded by an endless brown, dry landscape completely devoid of snow.

In an Olympic first, though not an achievement to boast about, climate variability has forced the Winter Games to be virtually 100% reliant on artificial snow -- part of a trend that is taking place across winter sports venues around the world.​
