The pattern isn’t unprecedented, but in the context of climate change, it’s hard not to look at things like this as previews of the future. Notice you said this is warmer and more persistent than 1917…as the years go by, these kinds of patterns will get more and moreso, until voila! Eventually a month like this won’t even be that out of the ordinary.

It’s been 9 degrees above average here, do you really think winters will warm up that much before 2250?

This December has been insanely mild here in the Pacific Northwest. Can’t help but it’s a preview of what the typical December will be like in…2250?

This cyclone, aka Senyar, ended up causing terrible flooding in Thailand, Malaysia and Indonesia (mainly Sumatra). According to Wikipedia more than 1,000 people were killed, and the storm caused nearly 20 billion dollars in damages - apparently the costliest Indian Ocean cyclone ever. All as just a moderate tropical storm and tropical depression.

Tropical cyclone four is forecast to make landfall in northern Sumatra as a moderate tropical storm. Due to its low latitude, cyclones hardly ever hit Indonesia directly. The only other landfalling one I could find was Vamei in 2001, but that made landfall as a tropical depression.

Fung-Wong just made landfall in central Luzon as a 115-mph typhoon, very large storm too. It’s forecast to move across Luzon at a good clip, so hopefully doesn’t cause too many flooding problems.

Impacts to southern Cuba sound pretty bad. ”In Guantánamo, Santiago, and other eastern communities, homes were damaged, essential services were disrupted, and nearly 450,000 people temporarily lost access to safe water. The provinces of Santiago de Cuba, Granma and Holguín have no electricity. To date, damage has been detected in 44 health and education institutions. Classes remain suspended in the eastern provinces. Several community food distribution centers were lost, and many people lost their fishing boats, livestock, and other means of subsistence. Recovery has progressed, but shortages and fragile infrastructure persist, worsening the impacts of Hurricane Melissa in these areas.” https://reliefweb.int/report/cuba/emergency-appeal-cuba-hurricane-melissa-mdrcu013

Preliminary damage estimates are $7.7 billion in Jamaica, which would be more than a third of their annual GDP. I’m sure we will see that number change a lot, but still.

Jesus…that footage is jaw dropping. Thank god Melissa didn’t hit Kingston, of course that’s small consolation for people living where it did hit.

Any thoughts on surge threat for Santiago de Cuba? I looked the city up on Google street view, there are some photo spheres showing that part of the colonial heart is just a few feet above the bay there.

The good news for Cuba is the forecast has shifted west, the NHC track now shows a landfall about 55 miles west of Santiago de Cuba, on a stretch of coast where hardly anyone lives.

The population there is a lot more concentrated in a single city than western Jamaica. You have one big city, Santiago de Cuba, with half a million people - and hardly anyone at all lives on the coast west of there. Right now the NHC tracks Melissa what looks to be 30 or so miles west of the city. Hopefully they escape the worst winds and surge. They are on a kind of estuary/bay so I’m worried it is surge prone.

That’s the thing, in the video he said that in fact homes in jamaica are often built a good bit above the river anyway. The threat (according to him) is moreso landslides/rockslides caused by huge amounts of rain falling on crumbling and steep terrain, rather than houses getting swept away by the water itself.

Not sure about this. In the geology video I linked to, the geologist actually compares Jamaica during Melissa to the Blue Ridge Mountains in Helene…and he says that this situation is actually worse. Jamaica’s river valleys are more prone to landslides because the rock is actively being uplifted by a fault, making the rocky slopes steeper and more fragile/prone to crumbling. The rock itself collapses - versus in the Blue Ridge, the slides are soil and debris, the underlying rock itself doesn’t slide away. Also he says that the rivers in Jamaica are really large in terms of flow, despite not being very long.

Yeah there are a couple hundred thousand people in that area (a few times less than around Kingston). It could easily be their worst hurricane in the modern era. https://www.tomforth.co.uk/circlepopulations/
