Three hurricanes - or tropical cyclones, as they are called in that part of the world - continue to spin in the western Indian Ocean as of late Thursday.
- Tropical Cyclone Pawan (locally, Cyclonic Storm Pawan) is a weak system that will bring increased moisture and may bring heavy rain and flooding to Somalia and other parts of eastern Africa into this weekend.
- Tropical Cyclone Belna is intensifying well off the northern coast of Madagascar, and could become a heavy rain and wind threat to the Comoros and Madagascar early next week.
- Tropical Cyclone Ambali is also spinning well to the northeast of Madagascar as the equivalent of a Category 2 hurricane, but is not expected to threaten land before dissipating. Ambali rapidly intensifying by 115 mph in 24 hours, making it the most rapid intensification in a 24-hour period in the Southern Hemisphere by a name storm on record and the second most rapid intensification globally. It also reach the equivalent of a strong Category 4 hurricane.

At 7:33 p.m. on Nov. 26, the No. 94 Cape Mendocino buoy operated by Scripps Institution of Oceanography Coastal Data Information Program recorded a maximum significant wave height of 43.1 feet, and that night also measured a wave of 75 feet. These waves were in water 1,132 feet deep and were at 13.3-second intervals.
Also at 7:33 p.m., the program's No. 168 Humboldt Bay North Spit buoy recorded significant wave heights of 37.6 feet, but in shallower water.
Significant wave height is the average of the biggest one-third of waves over a 30-minute period, according to James Behrens, a program manager at the Coastal Data Information Program. Typically, some waves at a given station are expected to be about twice as large as that average, hence the 75-footer.
The only significant wave height that the program has measured — higher than the one recorded at Cape Mendocino — was on a buoy at Ocean Station Papa, far out in the North Pacific, in December 2012. That was 49.8 feet.

The winter storm that blanketed much of the Northeast with snow on Monday, disrupting travel and closing schools, is expected to keep hammering parts of New England on Tuesday.
As the storm system moves slowly northeastward, some areas could get an additional foot of snow overnight and into the morning, forecasters said. Winter storm warnings and advisories were posted for most of Massachusetts, New Hampshire, Vermont and Maine.
"It's going to get cranking tonight and tomorrow morning," said Frank Nocera, a meteorologist with the National Weather Service in Norton, Mass. Metropolitan Boston, which already had four to eight inches of snow in some suburbs, could see those amounts double by Tuesday, he said, and further school closings and commuting problems were possible.
The storm delivered the first major snowfall of the season in the Northeast, but other than coming at a relatively early date, it did not pack many surprises for weather experts.
The Munich Climate Conference 2019
Last weekend the climate conference by the Germany-based European Institute for Climate and Energy EIKE took place in Munich, despite threats by leftist radicals.
More than a dozen leading international climate experts presented views that severely challenge mainstream alarmist climate science.
1. Alps glaciers smaller than today during much of the Holocene
Among the speakers was Prof. em. Christian Schlüchter is a leading Swiss geologist who studied the glaciers of the Alps in great detail for decades. In his talk he reported his findings from very old timber found in and below glaciers, and what those ancient tree remnants tell us about the glacial epochs of the Alps.

The Sierras are renowned for big storm totals and the past week is a very good example, from zero snow a week ago to seven-day totals of one to 2.4metres on the upper mountains, Kirkwood in California with the top reading. Not surprisingly, avalanche danger is high and mountain ops teams have been working hard to manage the snow and get more lifts and terrain open at all the Tahoe resorts for the weekend. There is a break in the storm action now, but not for long with another strong storm set to deliver 30-95cms for California from Friday night through to Sunday. Mammoth is looking good for 45cms at the base and double that up high, which will lead to more terrain opening over the next week.

Burundi's Ministry of Public Safety and Disaster Management said in a statement on 05 December that the landslide occurred in Nyempundu, Gikomero and Rukombe in Nyamakarabo zone, Mugina commune in Cibitoke province. Provisional assessments say that 26 people have died, 07 were injured and 10 people are still missing. Some media reports say the death toll has since climbed to 38. Search operations are still in progress. The Ministry said that houses, crops and livestock have also been damaged.
Heavy rain fell between 04 and 05 December, 2019. Images show that complete hillsides have fallen away in several locations. The area is still extremely unstable and the governor of Cibitoke, Joseph Iteriteka, urged people living in affected locations to evacuate their homes until further notice.
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) are both tropical depressions. The easternmost system (Invest #92B) is still developing.
Here is today's NASA MODIS AQUA satellite image of the West Indian Ocean - a pretty wild image of 5 tropical system simultaneously ongoing, making the Indian Ocean pretty busy from now on.

Lake effect snow piles on West Michigan
Some of the snow totals are mind boggling for early December.
Obviously the highest snow totals have been posted across the Upper Peninsula. Much of the northern half of the U.P. has received at least 2 feet of snow already. The highest seasonal snow total I've found is Chatham, MI, which is between Marquette and Munising and 10 miles from the Lake Superior shoreline. Chatham has already tallied 58.6 inches of snow.
Here's a map showing the snow totals so far this season. I hesitate to use the word "winter" because meteorological winter just started Dec. 1 and astronomical winter doesn't start until around Dec. 21.
