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)

Hurricane Melissa produced the fastest hurricane winds to be recorded by a dropsonde, verified by reviewing data at NSF NCAR! Hurricane Melissa’s 252 mph wind gust surpassed the previous record from Typhoon Megi over the Western Pacific in 2010, where a dropsonde measured wind gusts of 248 mph.

Anyone wondering why so many of us believe that the climate regime is fatally flawed, here’s the evidence: 30 years in (and in the middle of the COP30 meetings), and we are still nowhere near where we need to go! www.theguardian.com/environment/... #COPOut

Climate breakdown is driven by a storm of lies. This lying is systemic, funded and coordinated, and operates across almost all media, old and new. This week's column argues that we cannot fight the climate crisis without also fighting the epistemic crisis. www.theguardian.com/commentisfre...

And we warned them with our new 2025 State of the Climate Report which you can check out here: doi.org/10.1093/bios...

This is insane. 🤦‍♂️ Why do tech giants like Elon Musk and Bill Gates keep on saying such dumb things about climate change? They have access to the best possible experts, who could actually teach them something, if they would only ask and listen…

Surpassed 3 million views I was just alerted. Though I am talking weather, climate and science, it applies to a lot of biases people have... www.ted.com/talks/j_mars...

Alrighty, ready to see something really cool? (and maybe a little nauseating) The evolution of Hurricane Melissa's mesovortices at peak strength.

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) .

#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

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

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

If you blinked, you may have missed it. Hurricane #Erick made landfall on the Mexican coast as a major hurricane early Thursday. It broke records for so early in the season. 80 mph intensification in 24 hours and earliest landfall on the Pacific side of Mexico.

New paper in @rmets.org Weather from Gillian Kay & Met Office colleagues finds the max possible UK temperature in the *current* climate is a staggering 46.6°C. That's 6.3°C above the current record! We're not prepared for today's extremes, let alone those of the future. doi.org/10.1002/wea....
