What is a ‘bomb cyclone’?

Published

 on

A powerful storm is bearing down on the West Coast and bringing with it a scary-sounding weather term – bomb cyclone.

Bomb cyclone is a term used by weather enthusiasts to describe a process that meteorologists usually call bombogenesis. It’s the rapid intensification of a cyclone in a short period of time, and it can happen during powerful storms such as the one northern California and the Pacific Northwest are preparing for this week.

But what is a bomb cyclone, why does it happen and why are these big storms so feared?

What is a bomb cyclone?

A bomb cyclone occurs during the rapid intensification of a cyclone located between the tropics and the polar regions, according to the National Oceanic and Atmospheric Administration. It can happen when a cold air mass collides with a warm air mass, which is something that can occur over ocean waters, the agency says.

The measurement needed to determine whether a cyclone can be classified a bomb cyclone can be tricky, but it largely concerns a swift drop in pressure. Atmospheric pressure is measured in millibars by the National Weather Service. If a storm decreases 24 millibars or more in 24 hours or less, it can be considered a bomb cyclone, said Stephen Baron, a forecaster with the weather service in Gray, Maine.

“I would say rapid intensification of hurricanes is one of the more common times we see it,” Baron said. “We do see it with Nor’easters occasionally.”

Why is it happening on the West Coast?

The National Weather Service Weather Prediction Center has issued excessive rainfall risks starting Tuesday and running through Friday because of the powerful storm expected in northern California and the Pacific Northwest. The storm is arriving as the region experiences an atmospheric river, which is a long plume of moisture, over the Pacific Ocean.

The Weather Prediction Center said the storm intensified swiftly enough that it’s considered a bomb cyclone.

Bomb cyclones can happen in many places, and aren’t unique to the West Coast. They can occur in several parts of the world’s oceans, including the Northwest Pacific and North Atlantic.

What conditions could it bring?

This storm is expected to bring severe rainfall. That could lead to flash flooding as well as winter storms in different parts of the West Coast depending on elevation.

High wind watches are also expected in some parts of the West Coast.

Travel is expected to be hazardous, and power outages are expected. There could also be significant damages to trees and infrastructure.

When else has it happened?

Bomb cyclones have been associated with major weather events all over the country in recent years. Hurricane Milton, which made landfall in Florida last month as a Category 3 hurricane, was a recent example of a bomb cyclone, Baron said.

A bomb cyclone in 2018, which helped popularize the term on social media, brought snow to the Southeast and winds that were close to hurricane force. Another in 2022 brought extreme weather and bitter cold to much of the country.

Suspect at large after report of man with knife at University of Manitoba

Published

 on

WINNIPEG – Police in Winnipeg say a suspect is on the loose following a report of a man armed with a large knife at the University of Manitoba.

Officers were called around 6:30 a.m. to the university’s Fort Garry campus for a report of a man dressed in black carrying a large knife into the Allen Building, which houses the physics department.

Police and university officials had asked people to stay away from the area, and students already on campus were told to lock all doors and stay put.

Investigators say a suspect has not been found and officers remain on campus as a precaution.

In-person classes, exams and events were cancelled for the day.

Virtual classes and those on the Bannatyne campus were going ahead.

Last month, police said a man broke into a dorm room at the university and sexually assaulted a woman. A 46-year-old man was arrested and faces various charges.

Officers at a news conference Tuesday said that alleged assault did not influence how they responded to the knife report.

“This is an isolated incident that’s looked at for what it is, based on information we received. We don’t base that on prior incidents or to be careful. It has to do with this incident and how serious of a nature it was,” said police spokesman Const. Claude Chancy said.

Ontario First Nation declares state of emergency over gang and addiction crises

Published

 on

TORONTO – A northern Ontario First Nation has declared a state of emergency over concurrent crises involving crime, gang activity, addiction and mental health problems that have plagued the community for years.

Netmizaaggamig Nishnaabeg Chief Louis Kwissiwa is calling for policing and mental health help from the province and the federal government.

Kwissiwa says the community needs more police officers for a start, as well as professional help for the increasing number of people addicted to drugs.

He says addictions, violence, trauma and suicides are increasing.

There are just five police officers in the region, but they are a 45-minute drive away.

The solicitor general says he has spoken to the chief of Anishinabek Police Services about the seriousness of the issue.

TC Energy CEO sees opportunity in Trump win as company refocuses on natural gas

Published

 on

CALGARY – Donald Trump’s return to the White House is good news for Canada’s energy sector and an opportunity for TC Energy Corp., the CEO of the Calgary-based pipeline company said Tuesday.

François Poirier made the comments in a phone interview following TC Energy’s investor day presentation in Toronto. He said the former U.S. president’s re-election has been “top of mind” for the company, which has a network of natural gas pipelines in Canada, the U.S. and Mexico.

“He (Trump) is very focused on affordability. He understands the role that energy plays, and energy security, on the international stage,” Poirier said.

“Having the free flow of energy between the three countries in North America is very important. Natural gas and oil want to flow south, generally speaking. And having more supply of oil and gas from Canada will help contribute to lower prices in the U.S.”

As a company, TC Energy has already seen first-hand how business can flourish or be derailed by political winds south of the border.

Its Keystone XL project — a 1,900-kilometre proposed crude oil transportation pipeline that would have carried oil from the oilsands of northern Alberta to the major U.S. crude storage hub at Cushing, Okla. and then on to Gulf Coast refineries — was first proposed under the Obama administration, which rejected it on environmental grounds.

Keystone was then revived under the first Trump administration, before President Joe Biden killed it again by revoking the pipeline’s permit on his first day as president in 2021.

Last month, TC Energy completed the spinoff of its crude oil pipeline business into a new company called South Bow Corp., and as a result, TC is no longer the owner of the Keystone system.

South Bow “supports efforts to transport more Canadian crude oil to meet U.S. demand,” the company said in an emailed statement provided Tuesday by spokeswoman Katie Stavinoha.

“South Bow’s long-term strategy is to safely and efficiently grow our business,” the statement said.

But Poirier said the Alberta government has already reached out to TC in the wake of the U.S. presidential election, keen to see if that project could be revived or if there are other ways to increase Alberta’s oil and gas pipeline export volumes to the U.S.

Trump has proposed sweeping tariffs on all U.S. imports, but most experts believe Canadian oil and gas would be exempt from such a plan due to the highly integrated nature of the North American energy system. Trump has also been a vocal supporter of oil and gas generally, calling for more domestic drilling and tapping Liberty Energy CEO Chris Wright for secretary of the U.S. Department of Energy.

“We’ve had high-level conversations (with the Alberta government) around Keystone XL. We did mention that project is owned by South Bow … and for conversations around increasing the export of crude oil from Alberta, that would be for South Bow to consider,” Poirier said.

“Our conversations have been more around expanding access to U.S. markets for natural gas — both for export to international markets as well as into the U.S. markets, particularly in the northwest and the Midwest of the U.S. where Canadian natural gas has important market share.”

For TC Energy, a second Trump administration is timely because it coincides with what is already a renewed focus on natural gas for the company. The spin-off of South Bow was designed to enable TC Energy to pursue a natural gas-focused strategy at a time when the company sees growing demand for the commodity.

TC believes a combination of factors — including the phase-out of coal-fired power, increased exports of liquefied natural gas, growing electrification, and the rise of power-hungry data centres to fuel the AI revolution — will lead to a dramatic increase in natural gas usage in North America in years to come.

It predicts North American natural gas demand rising to a total of 160 billion cubic feet per day by 2035, an increase of 40 billion cubic feet per day from today’s levels. The company also believes natural gas and electricity will account for 75 per cent of total growth in overall North American energy consumption by 2035.

“We have seen this developing for quite a number of years … What I would say, however, is the degree of visibility that has developed over the last 12 months or so around data centres and around the importance of LNG exports has been more rapid,” Poirier said.

Approximately two-thirds of the 350 or so data centres currently proposed or under construction in North America are within50 miles of TC Energy’s assets, Poirier said, meaning the company is uniquely poised to benefit from the AI boom by supplying much-needed natural gas infrastructure to the power-hungry industry.

While some hyperscale data centre operators south of the border have announced investments in nuclear or renewable power to reduce their emissions profile, Poirier said he is confident natural gas will play a major role in the industry’s growth.

“The issue with wind and solar is that on its own, you don’t have 100 per cent reliability because these data centres operate on a 24/7 basis,” he said.

“They consume energy on a 24/7 basis, which is why we’re so confident in the role that natural gas will play in empowering data centre growth.”

On Tuesday, TC Energy announced it has green-lit a total of about $1.5 billion in capital spending across four new projects, including two in the U.S. that will help with coal-to-gas conversion at two existing power plants as well as the sanctioning of a liquefied natural gas peaking project in southeast Virginia.

It also said its share of the capital required at an expansion at Bruce Power is about $175 million.

Poirier said the company is committed to remaining within its previously sanctioned $32 billion sanctioned capital growth program between now and 2027, but added the prospective opportunities related to natural gas right now are huge.

“We see probably twice the opportunity set that we can afford to spend our human and our financial capital on, based on all the opportunities in our footprint,” he said.

“Actually the skill that we’ve had to learn is how to say no, because we see so many good projects come across our desks.”
