What are vulnerable areas that tend to get power outages from weather events or temperature extremes you know of or experienced?

The PNW WA and the (old) Oregon climate gets it hard from winds above 45mph you start getting into the 10,000 range then above 50mph goes into the 50,000-100,000 range pretty fast and so do ice storms of more then a quarter inch.

Has the Oregon climate changed since February?

Last Night’s Ice Storm Caused the Largest Power Outage in Oregon History

Over 330,000 Oregonians are currently without power.

Overnight, Oregon's ice-induced power outages went from widespread to historically bad.

According to a statement from Gov. Kate Brown, Oregonians are currently experiencing the largest number of outages in recorded history.

"While utility crews are making progress, the weather is leading to new outages faster than the pace of restoration," Brown said in a press release. "Utilities in our region have never experienced such widespread outages, including during the September 2020 wildfires."

Over 330,000 Oregonians are currently without power. Most of those outages are concentrated in the Willamette Valley.

This will have a lot more to do with the set up and resilience of the electricity distribution network than climate.

Eg in the UK urban and suburban areas seldom have power cuts, and those that do are rarely weather related. Some rural areas can have widespread power cuts caused by high winds bringing trees down onto the lines, but urban and suburban parts tend to have them underground.

Power outages (In my opinion) is controlled by the state and local towns maintenance and preparation skills. Especially the length of power outages..


While Connecticut is a small state we are very dense (lol)
Connecticut is approximately 61 percent forested
Connecticut is the 14th most forested state in the United State and that's amazing because it's the 4th most-densely populated state.


With that said..... a small thunderstorm or winds with 35mph can take down many branches which leads to power outages especially if ground is saturated.

With that said... When our power company wasn't ready for the October 2011 snowstorm we had over 1.5 million people without power in the state. After that storm they decided to be pro active about pruning trees away from wires. It helped a little with the next storm but they failed to call in help so we spent days/weeks again without power from a Tropical Storm.

Look into areas that get Thunderstorms, coastal storms, Tropical storms, Tornadoes, ice storms.

Northeast?

Yeah the parts of the world that are most prone to power outages are going to be less developed countries, which I imagine mostly have hot desert, hot steppe, and tropical climates (although North Korea has a monsoonal humid continental climate).

I agree it depends more on the robustness of the system than on the climate. Here in South Florida you would expect the power to go out all the time with the brutal thunderstorms and hurricanes we get, but it's extremely rare. The last time I can remember losing power for more than 1 minute in my Miami suburb was in 2005 during hurricane Wilma, that lasted about 3 days. Otherwise it might flicker on and off for a few seconds when there's a big thunder nearby but it never goes out. Although something we don't get climate-wise which seems to cause huge problems are ice storms. You hear about it a lot in places like North Carolina. It rains during winter, freezes overnight, and then all those big oak trees start falling over due to the weight of the ice and take out the power lines. That obviously doesn't happen in Miami, and even if it did for some reason most of our trees are palms that wouldn't fall over from ice (although they would surely die).

Depends where you live. My power lines are underground and don't remember losing power due to a weather event in the last 5 years.
