Two upper lows / frontal systems will deliver lots of snow and enhance flooding threat across south Turkey this week
While there is strong upper-level ridging maintaining over Europe and dominating much of our continent, this usually means troughs and upper lows are traveling south along ridge’s eastern flank, cross eastern Europe towards the eastern Mediterranean. Two of such features will develop this week, one is already ongoing and another one is expected to form […]
Three weeks after a very intense tropical cyclone #Ambali and a Tropical cyclone #Belna, a new tropical storm Calvinia is born east of Madagascar, precisely very near the French island Mauritius. It is resulting in dangerous excessive rainfall and flooding threat over the island, gradually organizing and moving south-southeast. Calvinia will be ejecting south tomorrow […]
Category 2 Tropical Cyclone #Sarai continues to drift eastward just south of #Fiji archipelago, expected to pass very near #Tonga for the New Year
Tropical Cyclone #Sarai is now in a slow but steadily weakening trend, although it remains a strong cyclone. It is moving eastwards along the southern part of Fiji’s archipelago, still having severe winds and heavy rain effects on the islands. Sarai will continue east through the remained of December, nearing the island of Tonga on […]
The dynamic pattern over North Atlantic lately is also pushing waves towards northern Europe, while extensive upper-level ridging is persisting over the rest of continental Europe. This weekend, strong westerlies brought a very strong warm advection into Scandinavia and temperatures warmed up for 20-30 °C in many areas compared to the past days! Temperatures this […]

#Sarai remains a strong Tropical Cyclone with Category 2 strength, pounding Fiji archipelago with dangerous flooding and damaging winds
Tropical Cyclone #Sarai has been steadily intensifying today as is now still a strong Category 2 cyclone, packing winds of 65-70 knots relying on Dvorak estimates. Based on the Australia & South Pacific TC classification, Sarai is close to borderline for a Severe Tropical Cyclone Category 3 (threshold 64–72 knots of maximum 10-min sustained winds). […]
*EXTREMELY* low temperatures are unfolding across parts of Alaska – Manley Hot Springs reported 65 °F below zero!
A *frigid* cold is verifying across parts of Alaska now. This morning, a low temperature of -65 °F (= -53.8 °C) has been observed 15 miles northeast of the town Manley Hot Springs! This is the coldest official temperature recorded in Alaska since January 2012 when -66 °F (-54.5 °C) has been recorded in Ft. […]
*10-20 day outlook* Year 2020 will start with a strongly positive Polar Circulation Amplification, dominating high pressure over Europe & Pacific and low pressure over North America!
In our previous installment, we looked at the long-range forecasts and seasonal trends. Now we will focus more on the medium/extended range, and what the early days of 2020 will bring. A few days ago, we had a look at the latest long-range/monthly forecasts. We have discovered, that they are all locked in, for a […]

A powerful high-pressure system dominates Europe until the New Year – brings stable weather through the last days of December
We will be going through the last days of 2019 with a powerful high-pressure system over Europe. It will maintain a rather stable weather across most of the European continent this weekend into early next week. Some more dynamic weather will be over the southeastern parts of Europe where upper low delivers a short cold […]
An explosive eyewall convection is now wrapping around the clearing eye of a Category 2 Tropical Cyclone #Sarai
Daylight has arrived over the Tropical cyclone #Sarai which is continuing to improve – a clearing eye with explosive deep convection is now wrapping around the eye. Poleward upper-level outflow ventilation is contributing to its evolution, allowing it to continue intensifying. Sarai is definitely gaining additional strength this morning. The Sarai’s center is staying well […]
UPDATE on the final cold blast of 2019 spreading across the eastern half of Europe, intensifying over the weekend and delivering snow for some regions
The last cold outbreak of the year 2019 is here – A temporal cold blast expected this weekend is already spreading across eastern Europe and the Balkan peninsula, resulting in much colder temperatures than experienced lately. Although the cold pool will be just temporal – it should be completed by the end of December, it […]

Tropical Cyclone #SARAI brushing the main Fiji island Viti Levu and is now a Category 2 Tropical Cyclone
As we discussed yesterday, a new tropical system – Tropical Cyclone “Sarai formed near Fiji, moving south-southeast, just west of the main island Viti Levi and gradually deepening. Maximum sustained winds are near 55-60 knots (= 65-70 mph / 100-110 km/h), a solid Category 2 Tropical Cyclone strength. Central pressure is around 985 mbar. Sarai […]
Another dangerous tropical system forming – a Tropical Cyclone #Sarai heading towards the island Fiji
We have just ended with the intense typhoon #Phanfone passing over the Philippines on Christmas day, there is another potentially dangerous tropical system developing – a tropical cyclone #Sarai, moving towards Fiji. Potential exists cyclone would bring dangerous flooding, storm surge and winds into the island in the coming days! Tropical Cyclone #Sarai a very […]
The dynamic pattern across North Atlantic has produced twins on Christmas – two very large cyclones yesterday and as expected, the eastern cyclone has weakened today while the western one has continued intensifying overnight and dominated. It is now a very large system, expanding across most of the North Atlantic. It will remain as such […]

Typhoon #Phanfone / #UrsulaPH has peaked over the western Philippines, now already over the South China Sea
Typhoon Phanfone was moving across the Philippines through the past 24 hours as a dangerous typhoon of strong Category 1 to low-end Category 3 strength. Dvorak analysis estimated it may have been a solid Category 3 typhoon during its peak hours today, with maximum sustained winds of around 110 knots / 125 mph and central […]
A temporal cold blast across the east-southeast Europe and the Balkans through the last days of December
A stable pattern will gradually expand across large Europe of Europe until the New Year, establishing a meridional flow across the eastern half of our continent.
