Major Hurricane Melissa - 892mb - 185mph Jamaica landfall
USCG RS replied to GaWx's topic in Tropical Headquarters
It depends on the codes adhered to, if any. Those resorts, given the investments made, tend to be pretty well built, specifically to handle these types of storms. Now, the flooding is a problem. And this is an unprecedentedly strong hurricane, so we'll see. -

As far as the buildings with concrete walls/ISO-2 builds, that will help, however, the main problem are the points of failure. In this case it will be the roof and without that lateral assistance to help the load bearing walls stay together, you risk implosion essentially. When buildings are constructed, part of the structural integrity comes from the roof tying the load bearing walls together. Combine that with the fact that the ground level pressure is so low while the winds create a potential pressure above 1000 mb inside the house due to the constraints of the winds inside such a small space and there is a strong likelihood that even the concrete wall buildings simply implode. -

Helene deleted parts of NC when it hit the area, and I mean truly deleted. It's like civilization was never there in some areas. This is similar in flooding and much worse in wind. Now imagine Jamaica which has nowhere near the infrastructure the United States has. -

200 mph... SUSTAINED That is the classification for an EF5 tornado. 200+. That's a 15+ mile wide EF5 Tornado. -
NAM 3K has the storm deepening rather strongly to the NC/SC border with a rather heavy band transversing the area tomorrow and then slowly decaying into the Mid-Atlantic states.

Like anything that governments create, especially for 'emergency' situations. Abuse eventually becomes rampant.

While I agree with you, it's not necessarily planning and coordination in terms of how to handle, it's about funding. Declaring a State of Emergency opens up additional funds from state and federal levels (mostly federal, though it is a bit complicated at times). So the SOE, while I will agree becomes like crying wolf, is really about opening of resources, most of which are financial.

Yeah this aged really poorly -

Keep an eye on this. We are still 36 or so hours away and SR models want to back this coastal in. This is not a system to sleep on. -

Yes, I remember this quite well. I lived in Ridge at the time. 1999. We got nearly a foot and it was snowing really hard for a while there. -

I could be-and have been before- wrong, but I've seen this song and dance before with the models in this set up. More often than not this area takes at least a significant hit. I would most definitely keep an eye on this. There's a ton of energy around and we have a relatively good macro scale pattern. This is not over yet imo. -

Only to Hr 144. Still snowing for the subforum at this point. -

To my understanding, it was more that the latent heat from the sheer amount of lighting in the atmosphere was enough to cause the heat to melt the snow.

So, during Nemo (Feb 2013), when the two streams actually phased, there was so much volatility and upward motion that it created a significant amount of lighting. This led to so much latent heat release that thunder snow turned to thunder sleet for nearly an hour. It was not the layers of the atmosphere, it was the actual lightning causing the snow to melt and then it refroze before hitting the ground. I always found that fascinating.
