A mobile Doppler on Wheels unit is surrounded by intense snow from a lake-effect storm over the weekend.
A recent lake effect snowfall in western New York offered researchers a rare opportunity to gather data about how wind turbines trigger "thundersnow"—or lightning within a snowstorm.

"Lightning damage is an increasing concern for wind power providers," reported the Washington Post, in the wake of the late-November storm that brought a record amount of snow to the east ends of Lake Ontario and Lake Erie. "Like any tall structure, a wind turbine can serve as a strike point for a downward-propagating lightning flash."

But "as turbines grow taller, they appear more likely to trigger upward-propagating flashes that extend from the turbine into a storm, rather than vice versa."

Mauna Loa eruption: Hawaii residents told to prepare for evacuation amid gas and ash warnings

mmmmmmmmm
People living on the slopes of the Mauna Loa volcano on Hawaii's Big Island have been told to prepare for a worst-case scenario as it continues to erupt and belch volcanic ash into the air.

Waves of orange, glowing lava are flowing from the world's largest active volcano in its first eruption in 38 years and officials told residents to be ready to evacuate if lava flows start heading toward populated areas.

While the eruption of Mauna Loa isn't immediately endangering towns, the US Geological Survey has warned the roughly 200,000 people on the Big Island that an eruption "can be very dynamic, and the location and advance of lava flows can change rapidly".

Governor David Ige said: "Lava flows are not threatening any downslope communities at this time and all indications are that the eruption will remain in the northeast rift zone.

Ace forecaster Bastardi: 'Something we used to see in 1970s', Warns of 'spectacular cold'

Risk of a "spectacular cold outbreak "...have countries let their guard down?

In his most recent Weatherbell Saturday Summary, veteran meteorologist Joe Bastardi looks ahead at the winter weather over the coming weeks across the globe.

What definitely distinguishes Joe from forecasters I follow here in Germany is that he doesn't rely solely on the so-called ensemble models to make his longer term forecasts, but goes way back into the archives and searches for similar patterns that took place even decades ago (analogues) in order to better discern which way the weather is likely to turn in the weeks ahead.

German forecasters like here , here and here like to put out videos once or even twice daily to report on what the many model ensembles are showing, which is something no one really needs a meteorological license to do. Too often you hear these weather pundits suddenly change their 7+ day forecast, in lockstep with whatever the latest ensemble run crunches out. Yet, most of us know that such forecasts are only valid until the next ensemble run because 7 days out the models can and often make U-turns.

The mudslide dragged debris and trees down the mountains towards the coast of the island of Ischia
A number of people are feared to have been killed after a mudslide triggered by heavy rains swept away homes on the island of Ischia, near Naples.

The torrent of mud and debris dislodged trees, engulfed buildings and dragged cars into the sea as it reached the coast early on Saturday.

The body of a woman was reported to have been found under the mud, and several other people are still missing.

Dozens of homes are cut off, with bad weather hampering rescuers.


Comment: Update November 28

CNN reports:
Landslide on Italian island of Ischia kills at least 8

t least eight people have been confirmed dead after a landslide hit the Italian island of Ischia on Saturday, damaging buildings and obliterating transport infrastructure in its wake.

Five people are still missing, the governor of the Campania Prefecture office in southwest Italy told CNN Monday.

Italian Prime Minister Giorgia Meloni declared a state of emergency on Sunday due to what she called "exceptional flood and landslide events," following torrential rain in the Gulf of Naples.

Videos and images shared by local and national authorities showed the destruction in Ischia's port town of Casamicciola Terme. The island lies off Italy's coast, west of the city of Naples.

The governor of Campania, Vincenzo De Luca, said in a statement on Monday that the region had allocated around $4 million "to meet the most immediate needs relating to the Ischia landslide."

He added the administration would "ensure adequate services for displaced families housed in temporary shelters."

On Sunday, the governor told a news conference that homes on Ischia that were not up to building code were partly to blame for the damage, adding they must be demolished.

The Italian government also began distributing €2 million ($2.08 million) in aid and assistance to the local population affected by the landslide, according to a statement over the weekend.

At least 15 people died Sunday in a landslide on a hillside where a crowd was attending a funeral in a popular neighborhood of Yaounde, the Cameroonian capital, the governor of the region told AFP.

Around them, a hundred residents and onlookers were kept at a distance by police.

Heavy snow hit northwest China's Xinjiang Uygur Autonomous Region and north China's Inner Mongolia Autonomous Region in recent days as a cold wave gripped large parts of the country.

Snow fell heavily over several days in northern Xinjiang, including Altay Prefecture, Yili Kazakh Autonomous Prefecture and Tacheng Prefecture. The snow, caused by a cold front, led to roadblocks and traffic jams, prompting local departments to initiate emergency responses. Over the past few days, as snow continued to hit Tacheng, more than 80 snow removal vehicles were put into operation.
