Another cyclone is strengthening north of Madagascar today, expected to make landfall on the island on Sunday
The tropical activity in the West Indian Ocean has became busy this week as several tropical systems are ongoing. While a very intense Category 4+ cyclone #Ambali is ongoing east of Madagascar, another cyclone #BELNA (originated from the wave 02S) is strengethening north of Madagascar with expected landfall on the western parts of island on […]
A very impressive rapid intensification currently underway with Tropical Cyclone #Ambali in the South Indian Ocean – now an intense Category 3 cyclone!
As we have discussed last night – A rare occurrence in the tropics – five (5) tropical systems are simultaneously ongoing in the West Indian Ocean, one of the tropical systems has organized into a tropical cyclone, but is unexpectedly strengthened into much more intense system than forecasted. Invest 92S has gone through an extremely […]

A fast-moving cyclone crosses the British Isles and delivers severe to extremely severe winds on Thursday, Dec 5th
The zonal flow pattern is established over Europe in the coming days, as deep troughs persist over the Arctic region with strengthening ridge to the south. As a result, several cyclones / waves will rapidly push into western Europe within the strong westerly flow and deliver unsettled windy conditions and locally lots of rain, leading […]
A rare occurrence in the tropics – five (5) tropical systems are simultaneously ongoing in the West Indian Ocean today!
A pretty impressive and rare tropical activity is currently ongoing int the West Indian Ocean. Five (5) tropical systems have developed or still developing and can be seen live on the satellites! The two northernmost systems (Tropical cyclones #06A and #07A) are already supporting tropical storm strength, while the southernmost systems (Invest #91S and #92S) […]
*Polar vortex cold* The tropospheric core of the polar vortex will meet high pressure from the North Pacific, initiating -30°C air mass transport into the United States next week!
Polar vortex covers a large part of the Northern hemisphere. It starts on the ground, and goes all the way up high into the stratosphere, reaching above 50km altitude. In the stratosphere, the polar vortex is usually just one large area of cyclonic circulation. Lower down, in the troposphere, where all our weather is, the […]

Cold outbreak across east-central Europe is washing out, replaced by warmer airmass across much of European continent again
Patterns across Europe are flipping once again. While a large part of our continent was experiencing at least some cold weather and locally snow lately, an establishment of more zonal flow results in warmer airmass spread again. As of today and tomorrow, a large cold pool across ESE Europe is vanishing and ridging is building […]
Super Typhoon #KAMMURI made a devastating Category 4 landfall near Gubat in Sorsogon province, Philippines today
Super Typhoon KAMMURI has made landfall at Gubat in Sorsogon province around 11 pm Monday local time as a strong Category 4 system! As expected, typhoon Kammuri continued its rapid intensification just hours before the landfall. A very favorable seawater conditions led to an incredible intensification, boosting Kammuri from Category 1 to Super Typhoon Category […]
*Rare tropical event update* Unusual twin tropical cyclones are about to form, going face to face on both sides of the Equator. North system first to form, but south one will be stronger and likely to hit Madagascar with hurricane force!
A rare situation that we wrote about two days ago, is now developing further. Twin tropical systems will form in the western Indian ocean, on each side of the equator at the same time. Tropical convection seen in the western Indian Ocean is now starting to organize. A tropical depression has likely already formed north […]

An incredible rapid intensification of typhoon #KAMMURI – now a borderline Category 4 just a few hours before making landfall near Legazpi City, Philippines!
Kammuri has intensified extremely fast in the past 12 hours, as based on the Advanced Dvorak Technique analysis, it has now near 117 knots (Dvorak number 6+) of maximum sustained winds, while it was still ‘only’ around 70 knots (Dvorak number 3.5) yesterday 18 UTC! A rapid intensification phase continues this local afternoon, likely resulting […]

Dec 1st *UPDATE* on the typhoon #KAMMURI, heading for the Philippines while strengthening – should reach Category 3 prior to landfall
A strong Category 1 Typhoon #KAMMURI is having occasional bursts of extremely intense deep convection, reaching cloud tops even below -90 °C again. Quite unusual to see so intense convection while the system is rather struggling to organize into a monster typhoon. However, Kammuri has been intensifying today and now appears to have a solid […]
*Rare* Twin tropical cyclone formation is expected early next week. Two systems will form in the western Indian Ocean, each on its own hemisphere, facing each other across the Equator!
A rather unique situation is setting up, where we will witness twin tropical cyclones, on both sides of the equator! Tropical convection is currently ongoing in the western Indian ocean, seen on the METEOSAT image below. In the coming days, more organized convection is expected. As current models indicate, double tropical cyclone formation is likely […]

Full 365-day animation of Atlantic ocean currents cooling and warming, seasonal temperature changes, and tropical systems leaving trails in the ocean!
Every year the Atlantic ocean undergoes many changes in surface temperatures, both up and down! We decided to do a high-resolution animation of these yearly changes. Data for this project was from the MERCATOR Ocean service. The animation can be find below. Of notice is the cooler trail left behind by strong tropical systems. One […]

Somehow unexpectedly, typhoon #KAMMURI is struggling with the more rapid intensification. Although the extremely intense deep convection is ongoing, the system is not yet ready to form an eyewall and better organization. The whole system is quite large and spinning, but there is no eye feature visible. Kammuri is now on its gradually accelerating west […]
The post Nov 29th update on the tropics – typhoon #KAMMURI continues towards Philippines appeared first on Severe Weather Europe.
The pattern flip this week leads into some extreme anomalies in some parts of Europe and North Atlantic through early December. While a cold outbreak develops over E-CNTRL Europe, a very warm airmass spreads into the North Atlantic and the Arctic region. A broad area of more than 15 °C warmer temperatures expands across a […]

An intense cyclone will develop a powerful winter storm with severe blizzard conditions across the Northern Plains, US on Nov 30th
The end of November brings a very powerful cyclone across the northern parts of the United States, technically a perfect textbook explosive surface cyclogenesis / bombogenesis cyclone with sharp frontal boundaries and severe weather. While strong pressure / temperature gradient will result in severe winds and together with heavy snowfall, also dangerous severe blizzard conditions! […]
Thursday, Nov 28th *update* on the developing outbreak of cold airmass across much of Europe in the next days
As discussed a few days ago, an outbreak of much colder airmass is scheduled this weekend across much of our continent. The pattern flips after a decaying intense cyclone over northern Europe with a building strong upper ridge over N Atlantic and W Europe, allowing cold airmass advection directly from the Arctic region far south […]
#KAMMURI has been upgraded to a Category 1 typhoon – models are consistent it will soon begin rapid intensification and head towards the Philippines
Latest analysis on Nov 27th 18 UTC, suggests Kammuri is packing maximum sustained winds of 65 knots / 75 mph with a central pressure around 978 mbar – this puts Kammuri into a typhoon Category 1 strength. Advanced Dvorak Technique (ADT) has been supporting slightly weaker data (987 mbar and 60 knots), but with 45-55 […]
