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

Expert comment about more destructive tropical cyclones as the world warms: theconversation.com/hurricane-me...

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

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 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...

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...

Further (extreme) heavy rainfall and floods for parts of #Spain due to #DANA (=Depresión Aislada en Niveles Altos) #Alice. After #Tarragona was affected yesterday, this time it is the region south of #Valencia and #Amposta. The satellite image shows a two huge, stationary storm systems.

Widespread power cuts affecting western and central Scotland just now as a result of damaging winds from #StormAmy (source: ssen.co.uk)

The rapid deepening of Storm Amy has begun. Over the next hours, the storm will travel across the jet stream and move to the left exit region of the jet stream where the most explosive deepening will take place.

#StormAmy means business Rapid cyclogenesis 978 to 946hpa, a drop of 32hpa in central pressure in just 18hrs..and perhaps dipping to less than 946hpa for a time during the period

#StormAmy probably being named very soon as models are in better agreement this morning. It could be a record-breaker in terms of low pressure for the time of year as well. W + N Scotland in particular is likely to see some intense winds with this one.

The possible outcomes for the weather later this week..

Quite worrying solutions recently in the global weather models regarding Humberto's post-tropical intensification. The system is forecast to deepen explosively while arriving Europe. The northern British Isles might be hit hard. 👀

While the Azores have seen some tropical storms and a few hurricanes in the past, #Gabrielle will be at the upper end of the climatological range in terms of intensity. People on the central islands in particular should take this storm seriously and prepare for it

Remarkable to see what hurricanes can do when they traverse exceptionally warm water. Gabrielle rapidly strengthening to a Category 4 hurricane today right as it passed over record warm sea surface temperatures for the time of year.

Very heavy rain across SE France last night in association with an area of strong thunderstorms. This is the season for intense convective events (often augmented by topographic features) around the Mediterranean Sea

UPDATE: Official 12-hourly precipitation data, 09/09/25, 6 UTC. Highest amounts: Bedburg (Germany) 134 mm Luxembourg Airport 122 mm Mönchengladbach (Germany) 122 mm

This one will happen very close to home...heavy (locally thundery) rain in far W Germany and surrounding areas. A few locations could see up to 100 mm in under 24 hours, enough to cause some flooding issues despite rather dry antecedent conditions. #weather

#lunareclipse2025 as seen in the Siebengebirge hills near Bonn earlier today.

High-shear/low CAPE setup in W Europe this afternoon/evening. Non-zero chance of a strong tornado event, too.

September 2nd, 1935: The infamous Labor Day hurricane slammed Florida. The Category 5 remains the most intense storm to have struck the US directly. Parts of the Florida Keys were completely devastated, with estimates putting the death toll over 400.

Tomorrow evening there is a slightly enhanced risk of a #tornado or two over Benelux and north-eastern France! Very prominent low-level shear and veering overlapping with weak/moderate instability. Strong forcing is possible just ahead of the approaching cold front. Sounding: @kachelmannwetter.com

20 years already. 😯 I'll never forget reading the NWS Baton Rouge bulletin on that day...chilling stuff.

Here’s a 48-hour water vapor loop of Ex-Hurricane Erin spinning on its final approach to Europe. Truly mesmerizing.

A peaceful scene near the High Fens in eastern Belgium on a recent chilly August morning, with a whiff of autumn already in the air. #landscapephotography

On this day 20 years ago: Tropical Depression Twelve forms over the central Bahamas from the merger of a tropical wave and the remnant mid-level circulation of TD Ten, assisted by an upper-tropospheric trough. The beginning of a generation-defining tropical cyclone, one named #Katrina. #wxhistory

The BAMS State of the Global Climate report 2024 reveals the year was record-breaking for both atmospheric water vapour levels and global temperature. Find out more in our press release: www.metoffice.gov.uk/about-us/new...

After an extremely hot start to the week especially over parts of Spain and France, the heat goes on across large parts of western Europe, with 850hpa temperatures at the upper end of climatology for the time of year today and on Thursday. #heatwave #canicule

August 7th, 1898: A pair of intense tornadoes affected the German Empire. The city of Cologne was ravaged by an estimated F4/T8 that damaged or destroyed several factories, numerous residences, and at least one church. Three people were killed, and ≥100 were injured.

From #Canada to #Europe! The huge plume from the Canadian #wildfires has reached #France, the #UK and Northern European Countries, as shown in the #Copernicus #Sentinel5p CO map on Aug. the 5th. #AirQuality

Scotland has provisionally had its strongest August wind gust on record, reaching 82mph at Wick Airport, according to the Met Office.

The unusually intense low FLORIS reaches peak intensity overnight, with a central pressure of 974 hPa over the northern North Sea—exceptional for the season. The storm even exhibits warm-core characteristics, acquiring a transient “tropical” structure with spiral and perhaps an eye.

The strongest earthquake on the planet since 2011 has triggered tsunami warnings for parts of Russia, Japan, and Alaska, as well as all of Hawaii. CNN's Will Ripley reports on the 8.8-magnitude quake. Follow live updates: cnn.it/3J8mcah

It will feel like a tropical storm for people living / holidaying on the W Danish coasts or in far N Germany in terms of rain and wind (only with lower temperatures and no, it is NOT a tropical system). High-res models indicate very heavy rain through late WED and local gusts between 80 and 100km/h

Turkey recorded its highest temperature on record on Friday with 50.5°C recorded in Silopi ⚠️📈 This exceeds the previous record of 49.5°C recorded on 15th August 2023 🌡️ This extreme heat is bringing serious health impacts and giving a very high risk of wildfires 🔥

In most of the world day-to-day weather variations are still much larger than long-term global warming. As a result, both daily record highs and daily record lows remain common. However as the world warms, new daily record highs consistently far outnumber new daily record lows. 🧪

A quite remarkable rainfall event is unfolding in south and east Denmark. Some stations have seen over 100mm in the past 24 hours, with Neble in the far SE recording 136.7mm so far. The Danish all-time 24h record is 168.9mm recorded in July 1931. There are increasing reports of flooding.

Tonight NYC recorded two inches of rain in less than an hour — for only the 6th time in city history. (Central Park records begin in 1869.) The city's drainage system is built to handle just 1.75"/hour. Increasing rainfall intensity is one of the most damaging aspects of climate change.

‼️ Concern continues to grow for dangerous & life-threatening flash flooding in the same areas hit by last weekend's devastating floods, with localized rain totals >10-12" possible. WPC Discussion: www.wpc.ncep.noaa.gov/metwatch/met... (Read the quoted posts for how the forecast evolved today)

Why isn't such a system already in place anyway? There are tornado sirens in many severe weather prone parts of the U.S. as part of the weather warning communication framework. The same should happen in flash-flood-prone regions, and this part of Texas definitely is one!

Sea surface temperatures reached exceptional levels in the NW Mediterranean in June–early July. The #MHW abruptly ended at the #LOV station in Villefranche, France, after a windstorm caused strong mixing. SST fell from 28.7°C to 18.8°C in ~24 h. 🌊

OTD 10 years ago a devastating (I)F4 tornado, the first of its kind since 1970, struck the Riviera del Brenta area of the Venice province causing massive damage, destroying numerous buildings, throwing cars and debarking trees. 1 man died and 72 more people were injured

WPC issued as many as six MPDs for the deadly flash flooding in the TX Hill Country starting yesterday evening and lasting through much of today. The first MPD generally set the stage for what was to come, while the next three shown were as the event unfolded.
