Grazalema, Spain, received over 2,000 mm (78 inches) of rain in just the last 20 days.

Over a year’s worth of rain — and it’s only early February. This is hydrologically absurd.

Bizarre scenes in eastern Germany after days of mixed precipitation. A layer of black ice and frozen snow several centimeters thick is causing chaotic conditions on the roads. Images via WarnWetter-App @dwdderwetterdienst.bsky.social #Winter #Weather #Snow #Ice

Time series of annual minima sea level at the Föglö tide gauge in 1924–2026. The value in 2026 is the lowest on record.

New all-time minimum sea level in the Baltic Sea!

The Föglö tide gauge measured just -71.6 cm below the mean level which is the lowest value ever recorded there. Records have been kept over 100 years, since 1924 (!).

The sea level is still decreasing. (1/3)

Massive smoke plumes from a large bushfire near Gellibrand, Victoria, yesterday which prompted emergency warnings in the area. The fire even produced a towering pyrocumulus and pileus cloud as the hot updraft pushed through stable layers in the mid-levels. #fireweather #stormhour

A spell of extreme heat and fire danger is on the cards across SE Australia.
We’ve been through 48C heat in the W Pilbara on 5 January, wasn’t fun 😅
Sth I noticed here: the visibility of information on natural hazards on many platforms, whether it’s cyclones, floods or fires. #weatherawareness

Landed in London. There was a CRAZY aurora outside on the flight over, I've never seen anything like it! Absolutely surreal...

Beautiful!

As the climate data for 2025 continues to be released, it's time to update various data visualisations.

First - the global climate stripes for 1850-2025. A third darkest red stripe is added.

The last 11 years have been the warmest 11 years on record. A sequence that is unlikely to be broken soon.

Is damaging hail getting worse? An ESSL-led study published in Nature Geoscience finds that very large hail is modelled to occur most frequently in South America, the United States, and South Africa, but Europe shows the strongest increase in very large hail frequency. doi.org/10.1038/s415...

Dust devils and a possible landspout in brutal 47C heat SW of Karratha, Western Australia, yesterday afternoon. #photography #stormhour

#Uluru, Northern Territory, with its famous evening glow a few days ago. There was quite a bit of high-based convective cloud that afternoon in 38C heat, so chances for a decent sunset didn’t seem that high at first.
But skies cleared enough just in time. #stormhour

It’s simply not possible to overstate how important NCAR is to US and world science. We need to fight this with everything we’ve got.

Colourful and hazy sunset earlier near Bowen, QLD, Australia after a hot and fairly windy Tuesday. There were some smoke plumes in the air from nearby (small) bushfires. #stormhour

Beautiful halo with a nicely positioned cloud above Airlie Beach, QLD, Australia earlier today. #stormhour #atmosphericoptics

Hurricane Melissa is a warning – why violent storms are increasingly catching the world off guard In a single day, Melissa exploded from a moderate storm into a major hurricane with 170mph winds.

Expert comment about more destructive tropical cyclones as the world warms:

This is amazing footage.

Wow. This is easily the most ridiculous dropsonde I’ve ever seen.

188 knot mean winds in the low-levels with gusts over 250 mph

Absolutely scary and historic hurricane headed into SW Jamaica this morning

With a central pressure down to 896mb as of 9am EDT, #Melissa has joined the elite sub-900mb group of Atlantic hurricanes... it is now one of just seven:

Wilma 2005: 882mb
Gilbert 1988: 888mb
Labor Day 1935: 892mb
Rita 2005: 895mb
Milton 2024: 895mb
Melissa 2025: 896mb
Allen 1980: 899mb

Melissa explodes into a powerful hurricane, and it is going to deliver catastrophic impacts to Jamaica Flooding, surge, and wind all look truly awful for Jamaica.

A true catastrophe is likely to unfold in Jamaica, as multiple days of rain followed by a direct hit from a top-end hurricane push the limits of what the country has seen historically. Details on the forecast, which aren’t much changed today below and at theeyewall.com.

NHC now explicitly calls for Melissa to reach category 5 intensity before striking Jamaica.

The addition of Google DeepMind’s FNV3 ensemble this year bolstered forecast confidence in extreme intensification — it’s doubtful the NHC forecast would’ve been this aggressive without FNV3.

This could become a catastrophic flood and wind event for Jamaica in particular.

Tropical Storm Melissa not yet strengthening, but still expected to become a dangerous Caribbean hurricane » Yale Climate Connections The track forecast is more uncertain than usual, but Melissa is likely to bring colossal rains and life-threatening flooding to multiple islands in the Caribbean.

Tropical Storm #Melissa has not yet strengthened. But this actually bad news, since a weaker storm is more likely to linger in the Caribbean and become a major hurricane, as @bhensonweather.bsky.social and I explain:
yaleclimateconnections.org/2025/10/trop...

There has been huge progress in tornado and severe thunderstorm related research thanks to @essl-ecss.bsky.social and some others in the last two decades, but this doesn't always translate into broader risk awareness and education, including in the public/media sectors.

We have a similar situation over here in Germany, unfortunately, even though we have seen a few "high-profile" cases in recent years, e.g. Paderborn 2022, Bützow 2015, etc.
I would say that there has been some improvement in terms of awareness, but the warning & comms systems are still inconsistent

Tornadoes in France today. At least one death and 9 injuries, unfortunate but somewhat inevitable when a significant tornado (seems to be at least an IF2 to me) strikes such a populated area. Europe has a severe lack of tornado awareness and when a violent one will strike a highly populated area...
