Nino3.4 region sea surface temperature forecast.

Wow, that's a monster signal for El Niño in today's new ECMWF seasonal forecast.

Wow! 37.9” (96 cm) of snow has fallen in Providence, Rhode Island, pulverizing the previous all-time single-storm snowfall record by over 9”.

Et c'est encore plus flagrant du côté de Brest par exemple.

For the first time since records began in 1950, France’s multi-week national MSLP has dropped below 1000 hPa. The persistence of this low-pressure pattern across western Europe in recent weeks has been nothing short of historic.

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.

Hi, thanks for the information! Do you happen to have a rough idea of the cost for purchasing the data? Also, could you share the link to the AEMET page where this can be requested? I’ve never gone through this process before, so that would be really helpful.

Hi Diego, to my knowledge, AEMET Open Data only provides daily data for Grazalema station 5911A starting in 2000. Do you know where I could download data for earlier years? Thank you.

Cuba 🇨🇺 has just recorded its lowest temperature on record this morning, with 0.0°C (32°F) at Indio Hatuey. This marks the first time in recorded history that the country has reached the freezing point.

The hydrological situation across a large part of the Iberian Peninsula is alarming, to say the least, and conditions are set to worsen as several powerful atmospheric rivers are forecast; major flooding cannot be ruled out.

Portugal and Spain are looking at tremendous precipitation from an onslaught of atmospheric rivers over the next 14-days. Flooding will certainly be a very real threat if these numbers materialize.

Storm Harry poses an extremely dangerous flooding threat to the central Mediterranean. The most extreme rainfall is forecast over eastern Sicily, especially the Province of Catania, where more than 500 mm of rain may fall in less than 48 hours.

Chilling satellite imagery emerging as #StormGoretti unleashes full fury upon parts of the UK and France. A 213 km/h wind gust was just reported at Gatteville-le-Phare (Manche) in northwestern France.

The latest high-resolution Met Office UKV model remains particularly aggressive regarding the impacts of Storm Goretti (named by Météo-France), with gusts of up to ~200 km/h modeled in the English Channel.

Gorgeous satellite view of the fresh snow cover across northwestern France🇫🇷

I can’t recall ever seeing a fog event footprint show up so clearly on a 30-day temperature anomaly map. Absolutely fascinating.

California’s Central Valley really sticks out amid widespread warmth across the West.

It's hard to grasp the immense scale of the Indonesia floods until you see it from space.

And this is just a fraction of the full extent.

Details: This imagery showcases a composite of every category 4 and 5 hurricane in the Atlantic ocean since 2020, using the GeoColor product from the GOES-16 and GOES-19 weather satellites. It spans from 22:30 UTC on 2020-08-26 (Hurricane Laura) to 14:00 UTC on 2025-10-28 (Hurricane Melissa).

Every Category 4 and 5 Atlantic hurricane since 2020, all together, in one group photo.

H/t to @ferragamowx.bsky.social for the inspiration.

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.

A big change of air mass is on the way.

This has to be unheard of. With an extraordinary peak flash rate of 699 flashes per minute just prior to landfall in Jamaica, Melissa probably set the record for the most prolific inner-core lightning outbreak ever recorded in an Atlantic hurricane.

This is wild. Despite having fueled one of the strongest Atlantic hurricanes on record, the waters in the vicinity of where Melissa tracked remain sufficiently warm to support the formation of a major hurricane.

NOAA aerial imagery is coming in. Hurricane Melissa literally turned western Jamaica from green to brown. Vegetation damage is immense — recovery will take years.

With 40 cm of snow left on the ground last Wednesday, Iceland’s capital, Reykjavík, officially experienced its biggest October snowstorm on record. This historic event shattered a 104-year-old record by 25 cm.

Wow. Do you have a link to this station data?

The fact that we went nearly 20 years without a sub-900 mb Atlantic hurricane and now we’ve had two in just the last two seasons.

Melissa shattered the record for the driest eye ever recorded globally with an incredible -2.25°C, smashing the previous record by nearly 3°C (Typhoon Meranti, 2016).

White House — Landfall point.

Alrighty, ready to see something really cool? (and maybe a little nauseating)

The evolution of Hurricane Melissa's mesovortices at peak strength.

NEW: Devastating imagery from Jamaica, before & after Category 5 Hurricane Melissa.

Black River — near total destruction.

Hurricane Melissa’s historic journey to becoming one of the most intense tropical cyclones ever recorded on Earth.

A storm we won't forget anytime soon.
