Vog update

As I was driving back from an errand in Puna this a.m. I saw what looked like a grey felt blanket thrown over Mauna Kea from about 3,000 feet (my estimate) up. There was a sharp line of demarcation between the voggy and clear areas. The trades are back, and it's clear here, as this photo from 10:00 a.m. today shows. In the distance you can see the plume from the Pu Oo eruption  25 miles from my house, which has been going on for years. The problem now is that there is so much vog that it takes very strong trades to blow the added emissions away, the emissions emanating from Halemaumau.  So in spite of the trades, areas of the Island are experiencing a lot of pollution. Where there used to be one major source of vog, now there are two sources.
