As of 20h, the lowest temp I can see on the #Highland #Wundermap is -7C at Inchbae Lodge (on the road to Ullapool). Meanwhile, a personal #wx stn in the deep Gleann Beag of #Glenelg is not far behind at -5.5C (having had an ice day too)

#StormAmy boomerang loop of #Meteosat12 #MTG water vapour 6.2micron channel imagery over 36h (3-4 Oct 2025) shows extent & expansion of deep dry air intrusion, before being spun majestically around the record-breaking deep cyclone centre #VorticityInAction

At this stage, it's probably worth mentioning the #rain totals too! #StormAmy (thank you @scottishepa.bsky.social) . Already topping 100mm/36h at many stns in the west, after a drookit week www2.sepa.org.uk/rainfall/

Aargh.. Tiree appears to have lost power for 20h (19z) SYNOP report.. (just when you want it most)

What a beauty... a terrible monstrous beauty... #StormAmy #Humberto from METEOSAT-12/ MTG water vapour 6.2micron channel: The dark area is dry, descending air. Where it forms the scorpion's tail in the final frame (dare I say "sting") is location of some of the most violent winds

1st time I have seen #Noctilucent clouds BEFORE sunset... [it's them alright, as there's nought on the IR satscan, being too optically thin].. . Why so widespread? Learn more here press.princeton.edu/books/hardco...

On this day 121 years ago, a man walked about Dublin... he was not a meteorologist... but he was a great meteorological observer... there are >500 references to the #weather in #Ulysses, he even got the cloud shadows in the right position! #Bloomsday (Fadograph of yestern scene: Sackville St)

Here it comes now! (this is unusual, I don't recall such a thick smoke plume from Canada before, in the modern satellite era)
