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

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

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...

#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.

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.
Exclusive: The Trump administration is moving to dismantle the National Center for Atmospheric Research in Colorado, according to a senior White House official, taking aim at one of the world's leading climate research labs.

This is amazing footage.
This is footage taken earlier today of the eye of Hurricane Melissa.
The entire view is remarkable, of the core of one of the strongest Atlantic basic hurricanes in recorded history, and a catastrophic hit to Jamaica and the central Caribbean.

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.
1:52 PM EDT, 10/25: #HurricaneMelissa, a Category 1 hurricane with 75 mph winds, is SW of #Haiti. It is expected to rapidly intensify and reach high end #Category4 (possibly #Category5) #Monday as it moves towards #Jamaica, with heavy #rainfall (up to 30”/750mm) & #flooding forecast.

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:

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.

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...
Oh, that's interesting ! So far, we have two tornadoes for today, but not on those locations !
