Not to mention site changes too

Thanks Lars - I expect there are quite a few inhomogeneities in the wind speed & gust record over the decades due to instrumentation changes; we briefly mention a few (e.g. Dines V cups) in Graham, E. and Smart, D., 2021. 'Hurricane' Debbie–60 years on: a fresh analysis. Weather (00431656), 76(9).

And Tiree also recorded 90kn on 16.9.1961 during #Debbie

Spot on Lars! #Tiree 102kn on 15.01.1968 during the #GreatGlasgowStorm (Tranter, P. and Galvin, J., 2018. Fifty years on from the Great Glasgow Storm… What have we learned from powerful storms since then?. Weather, 73(2), pp.39-45) .

Yes, I think you're right, Lars! Let me double check...

Marco, I wonder if Tiree recorded even higher than 83kn (96mph) after the power went near 6pm?

#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/

South Uist 03023 SYNOP had a pressure tendency (drop) of -19.7hPa (mb) in the 3h to 16z today #StormAmy - exceptional but not unprecedented... I wonder if any pressure kicks can exceed 20hPa/3h (which would be remarkable) and akin to #Debbie 16.9.61

Behaving much like the "eye" of a hurricane... don't be deceived!

20z (21h) SYNOPs appear missing from #Tiree #Altnaharra #TullochBridge #BealachNaBa Widespread power outages across Highlands & Islands from #StormAmy on #SSE power map powertrack.ssen.co.uk/powertrack

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
