Extra-tropical storm #Dennis in its final stage, moving towards Scandinavia while gradually weakening
We are at the final stage of large cyclone #Dennis tonight through Monday. While it continues moving east into northern Europe, it is weakening and delivering severe winds into SW Scandinavia. Also, lots of rain and snow into SW Norway, increasing the avalanche threat. 18 UTC analysis today revealed Dennis’ center has the minimum central […]
A very warm airmass spreads across parts Benelux, Germany, Poland, and the Alps tonight, pushing night time temperatures close to +20 °C
Ahead of the large extra-tropical cyclone #Dennis over the North Atlantic and western Europe, and its associated surface cold front, a powerful warm advection is delivering an incredibly warm airmass into northern France, parts of Benelux and northwest Germany this evening. The event is related to the strengthening warmth wave over continental Europe this weekend. […]

Extremely deep 920 mbar and powerful extra-tropical storm #Dennis brings the title ‘The perfect storm’ back to North Atlantic – heading towards the northern UK on Sunday
The ‘bomb cyclone’ #Dennis took it seriously, no doubt about that. What we have seen today (Saturday, Feb 15th) is indeed beyond exceptional and photogenic for extra-tropical cyclones no matter where. The structure, its behavior and satellite presentation is simply EPIC! The system has deepened to remarkably low pressure for North Atlantic, 920 mbar this […]

*BREAKING* The Antarctic region has measured an incredible new absolute temperature record of +20.7°C (69.35°F), as an abnormally warm airmass moves over the Antarctic peninsula!
Only a week ago, a new highest temperature record has been reached for the continent of Antarctica. It was measured at the Argentine station Esperanza, situated on the Antarctic peninsula. But now an even higher temperature has been measured on Seymour Island. The continent of Antarctica has experienced its warmest temperature on record, reaching 18.3°C […]

*UPDATE* on the most intense North Atlantic storm of the season – an extremely rapid intensification of the ‘bomb cyclone’ #DENNIS is underway!
The bombogenesis / explosive cyclogenesis #Dennis is underway across the North Atlantic this morning, centered northwest of Ireland. The intensification rate is very extreme as the observed pressure falls are more than double the threshold for the bombogenesis! The pressure change during the past 24 hours has been unprecedented, as it has changed from 987 […]
A very dynamic North Atlantic leads into strong ridge and extreme warmth across parts of Europe from Sunday through Tuesday
While the main focus is on the volatile environment across the North Atlantic and western Europe these days, such pattern is usually responsible for upper-level ridging over Europe. Resulting in much above normal temperatures. This weekend, an extreme warmth develop over central Europe first, gradually spreading across eastern Europe and the Balkan peninsula until Tuesday. […]
A ‘bomb cyclone’ #Dennis could challenge the most intense North Atlantic cyclones on record this weekend – expected to bottom at around 915 mbar and push a severe windstorm towards western Europe
A new intense North Atlantic windstorm #Dennis could potentially push its central pressure to near or even below 915 mbar tomorrow, challenging the all-time lowest pressure record. The record-holder is the Braer storm, which occurred on Jan 10/11th, 1993. Its lowest pressure bottomed at 913 mbar and remains the most intense extra-tropical cyclone ever recorded […]

The intense windstorm over Iceland has resulted in extremely severe winds in some areas, especially where downslope winds have contributed to violent gusts exceeding 200 km/h. The weather station Hafnarfjall reported an incredible wind gusts of 255.6 km/h (= 71 m/s = 159 mph) this morning, 11 GMT. The hourly average was 108 km/h (= […]

Latest satellite imagery and weather station data across Iceland indicate the extremely severe winds are fully developed across the North Atlantic. The mature stage of a very large extra-tropical cyclone has brought a strong pressure gradient across Iceland, where the most exposed locations are already reporting 200-220 km/h wind gusts this morning. Conditions will worsen […]

Explosive cyclogenesis underway across the Northwest Atlantic, while the system is creating tandem of twins – it is connected to the cyclone nearing the UK and Ireland
As expected, the Northwest and North Atlantic are creating a spectacular show tonight. A very impressive satellite presentation is seen on the explosive cyclogenesis near the Newfoundland this evening, the system has deepened for a remarkable 50 mbar in the past 24 hours – more than a double threshold for rapid intensification/bombogenesis cyclone (-24 mbar […]

Both North Atlantic and Pacific are often active at the same time, but how often do you see both having so active cyclones and both having tandem of twins? Well, it is happening right now. Let’s focus on the Pacific in this post, but don’t miss the North Atlantic (see the link at the bottom). […]

Quite significant Arctic cold outbreak is foreseen across southern Canada into the northern half of US, starting today and gradually spreading across the Great Lakes into the northeast US by Saturday. Some snow will also occur across the Great Lakes and Ohio valley, but nothing too significant. The current pattern across the North American continent […]

*ICE recovery* Arctic sea ice reaches the largest early February ice area in the past 11 years! It even exceeds the 2001-2010 average size
Overall, winter was rather mild across much of Eurasia and North America, with the exception of Alaska and parts of Canada. But, that means that a lot of cold air has stayed in the polar circle, helping to freeze more of the Arctic ocean and the surrounding areas. The latest sea ice analysis shows that […]
Probably the most intense extra-tropical cyclone of the season will be seen across the North Atlantic on Thursday and Friday
Yes, you’ve read it right. No overhype or impossible feature. After seeing so many impressive deep cyclones / extra-tropical systems this winter (on both North Pacific and North Atlantic), there is a room for more! Correlated with the ongoing North Atlantic Oscillation and Arctic Oscillation near-record values, the weather is going into extremes! What we […]
Feb 12th morning *update* on the potentially strong low-pressure system blasting into Ireland, Wales, and England with intense front and wind squalls tonight
As we discussed yesterday, another deep low-pressure system is expected to move across the western Europe tonight, starting a new dynamic pattern over the North Atlantic. The system will deliver severe winds locally in excess of 75 mph / 120 km/h tonight into Thursday morning hours. Violent systems, including an extremely deep cyclone #Dennis, will […]

A Severe Tropical Cyclone #Uesi is passing near New Caledonia as a Category 3 strength, should approach southeast Australia on Friday
The Severe Tropical Cyclone #Uesi is now a Category 3 system and looks fairly impressive on the satellite scans, with textbook outflow upper-level ventilation. Is was passing just shy west of New Caledonia today, bringing strong to severe winds and torrential rainfall across the western part of the island. It is now, however, in the […]
A new deep low-pressure system brings severe winds into England, Ireland, Wales and Bay of Biscay through Wednesday night, also some fresh snow across northern England and Scotland
Just a few days after a powerful windstorm across western Europe, a new deep cyclone pushes into the region late tomorrow. The upper-wave with the surface frontal system is currently ejecting off eastern Canada and will be developing hurricane-force winds while moving across the North Atlantic within the next 36 hours. It brings severe winds […]
