A Great Lakes storm underwent bombogenesis early Tuesday and produced damaging winds that whipped up impressively high waves in Lake Superior.

The low-pressure system intensified from a weak area of low pressure over the Ohio Valley Monday morning to an intense low centered near Sault Ste. Marie, Michigan, early Tuesday morning.

The rate of intensification - a 27 millibar drop in the surface low in 24 hours - satisfied the criterion for atmospheric bombogenesis, or a rapidly strengthening low pressure system.

Winds near the Lake Superior shoreline gusted to over 60 mph Tuesday morning and downed trees and powerlines in over two dozen locations in Alger, Marquette and Schoolcraft counties.


Wind instruments about 115 feet above the lake surface at Stannard Rock Lighthouse, about 40 miles north-northeast of Marquette, Michigan, measured a wind gust of 77 mph Tuesday morning.

One of the little known dangers of lightning is that it can strike dozens of miles away from the actual thunderstorm itself.

Or in one case this week, hundreds of miles.

The new GOES 16 satellite has an advanced lightning sensor and captured a flash that started from a thunderstorm in southeastern Kansas and propagated about 250 miles across parts of Oklahoma and Missouri, according to NOAA:

A record-breaking snowfall knocked out power to thousands of customers Tuesday and shut down bus routes in northeast B.C.

According to Environment Canada meteorologist Lisa West, 23.0 cm fell in Fort St. John, beating the previous daily high of 15.2 centimetres on October 24, 1933.

An additional 32 centimetres fell on the city Wednesday morning for a total of 55 centimetres.

"That came close to but didn't break the old [October 25] record of 35.6 centimetres set in 1918," West said.

All city buses in Fort St. John were cancelled until 1 pm, waiting for snow ploughs to clear the roads.

All school buses in Peace River North and South, which include Dawson Creek, Fort St. John and Chetwynd, have been cancelled. Schools remain open.

The disturbance is likely to drift across the northwestern Caribbean into Friday, then across the Florida Straits and part of South Florida on Saturday, according to AccuWeather meteorologist Dan Kottlowski.

On Sunday, it's likely to take a path parallel to the Atlantic coast of the U.S., he added.

As Jakarta transitions into the rainy season, most of the Indonesian capital's residents are probably worried about the possibility of epic flooding like in years past, but a series of tornadoes, one in Bekasi and three off the coast of Jakarta in the capital's Pulau Seribu (Thousand Islands) subdistrict show there are other kinds of extreme weather phenomenon we need to watch out for.

The Bekasi Regional Disaster Mitigation Task Force (BPBD) says a tornado hit several homes on Jalan Raya Pangkalan II in Jakarta's satellite city of Bekasi on Sunday afternoon.

Fortunately, there were no casualties or injuries reported. However, the BPBD says a total of 20 homes were hit by the twister causing about IDR 60 million (USD 4,436) in damages, mostly to the roofs of the buildings.
