Oof. This is ramping up to be quite the hurricane/monsoon season.

I don't know much about meteorology, so I'll post this without comment besides the article's subject; maybe someone else can make an informed value judgement. But apparently as global temperatures rise, the atmosphere is going to be able to hold a lot more water:

I remember reading a few days ago that European models were predicting a turn to the north, and US models were predicting a high pressure ridge holding the hurricane to the west.

Anyone know more about this?

Because if true, it's the second time European models were more correct than American ones. Last time they decided we needed more supercomputing power, and they got it. Did it help?

I know that this is slightly off-topic so feel free to downvote if you feel so inclined:

There's a lot of money that goes into disaster relief and recovery. I think that's great and very worthwhile, thoughts on charity accountability notwithstanding.

What I wonder, though, is if there are any organizations that provide pre-relief (prelief?) for disasters. For instance, the comment in this discussion about the airlines overbooking for flights out of the Turks made me think, "we've known that this is a possibility for a while, could aid funds be provided to get folks to safety in advance?" I know that there are a lot of logistical problems to solve (where do they go? for how long will they stay? what about their lives/livelihoods at home? how does an organization maintain accountability with donations for a disaster that has yet to happen?)

Anyway, it's just a thought. I didn't know if such an organization existed, or if it's even feasible.

Hurricanes rotate counter clockwise, so the highest wind speeds and storm surge tend to occur to the "right" or on the east/southeast side of the eye path. Currently Miami looks to be right in the center of this danger zone, so just get out now while you still can. Yes it's a few days out and they can and usually do veer off, but this one is not worth riding out.

Hasn't Miami been sinking a bit over the past few decades? I would imagine it wouldn't take much storm surge to flood parts of the city. In that case, they really don't wanna be on that side of the storm.

The atmosphere can hold more water, and the oceans hold more heat. Hurricanes thrive on warm water (especially deep warm water, as the hurricane will churn up water from deeper levels, which can weaken it significantly if it's stirring up a lot of cold water).

One of the reasons Harvey intensified so quickly is that is passed over a _very_ warm section of the gulf:

Irma will be passing over similarly warm waters for the next 4-5 days:

The northern Leewards and Greater Antilles are in for a _really_ rough time. It's likely a direct hit (or close brush) with either Hispaniola or Cuba will weaken Irma before it turns north into Florida, but that's still really bad news for folks in the northern Caribbean, and it's still going to be a very serious storm when it hits Florida.

The models are converging on a northward turn right around the southern tip of Florida. We're still too far out to be talking about which one was 'right' or 'wrong' (it's common for there to be a lot of variability in the 5+ day forecasts).
