Really wishing it was coming across just a little bit further south. We have duck loads of rain and wind but nothing is cancelled so I have to sit my rear end at work all day and then drive to class later

The Goatfather posted:Lol at this dumb gently caress who learned nothing from sandy and katrina and thinks the category system is meaningful or useful beyond predicting wind damage It's you. You're the guy who doesn't know storm surge is primarily dependent on wind speed, storm approach angle, and coastal topography, and has been modeled by the NHC since like 2008.

The Goatfather posted:Yeah the single biggest factor definitely isn't whether it hits as the tide is high/rising. Oh wait it is! By virtue of being a tropical cyclone the wind is always going in the right direction to maximize storm surge somewhere along the coast where it makes landfall. The storm speeding up or slowing down in the hours before landfall can make a huge difference in the storm surge if it means the storm hits as the tide is rising instead of falling and this is impossible to predict accurately in time for anyone to sanely not prepare for the worst. Not to be that guy, but what you're talking about is called "storm tide". Storm surge is the height of the water compared to the normal astronomical tide, and is a function of the intensity of the storm, the angle at which the storm is approaching the coast, the local topography, and the speed at which the storm is approaching. Storm tide is the total observed water level, or the storm surge added onto the level caused by the astronomical tide. Storm tide is where the tide level matters, storm surge does not. Also, storm speed affecting storm surge isn't about "what tide the storm arrives on" or whatever. In open areas, faster moving storms generate bigger surges because they're pushing the water faster than a slow one would. But in bays or semi-enclosed areas, a slower storm causes higher water levels because the water piles in on top of itself and can't get back out to sea. Also also, the tide currently changes by about 2.5 ft in the big bend area of florida. So for a 9 foot storm surge the tidal difference is like 22%.

I believe Dr. Young accurately described all hurricanes back in 1977 via a 7-minute guitar solo that sounded much like 100 sq ft of aluminum siding flying down an abandoned street and directly into an industrial wood chipper. It's true. It's Florida's state song, and they play it at every baseball game
