Hurricane Dorian Is Barely Moving at All. Here's Why That Makes it Especially Dangerous (time.com) 141

Hurricane Dorian, which slammed the Bahamas early Monday as a catastrophic Category 5 storm, is packing remarkably strong winds -- but the storm itself is crawling along, moving at a mere 1 mile per hour early Monday before slowing to "stationary" as of Monday afternoon. The storm's glacial pace will result in even more devastation, meteorologists say. From a report: With sustained winds of 185 mph and gusts up to 220 mph at the time of landfall in the Bahamas, Dorian made its mark as one of the most powerful Atlantic hurricanes on record. While it was recategorized as a Category 4 storm late Monday morning, with winds of 155 mph, it remains an extremely dangerous storm, forecasters say. In part, that's because it's moving so slowly. Adam Douty, a meteorologist with AccuWeather, says Dorian will move as slowly as 1 or 2 mph "for the next 12 hours or so." For those in Hurricane Dorian's path, that's a big cause for concern. A slow-moving storm "makes the flooding worse, you have continued battering with the wind so it has time to weaken structures, and once they're weakened it could damage them further," Douty says. In addition, Dorian will likely cause significant coastal erosion along the coast with "hours and hours of waves" in the Bahamas.

    I would have thought that would be pretty obvious. Imagine an F2 tornado, which sometimes becomes an F3, 35 miles wide, and just sitting over top of an area for hours and hours.

      Well also the rain. Tornadoes don't necessarily come with rain, hurricanes almost always come with floods. It's easy enough to build structures to withstand(get under ground), but very difficult to withstand flooding(your best bet it to get up high). So in a hurricane you basically have a choice of being up in the air where the wind and debris will kill you or low where the flooding will kill you.

          They still got flooded though, thus proving the point being made.

      Also, as sheltering-in-place becomes less tenable people are forced out into the wind and worse, the flood. It's floods that kill most people in hurricanes.

      The Saffir-Simpson scale only takes sustained wind intensity into account; really that's one of four factors that describes the destructive potential of a storm: wind, flooding potential, geographic extent, and speed. Super-storm Sandy wasn't even a hurricane by the time it made landfall, but it was the second geographically largest Atlantic hurricane

      Sort of. Having danced in a few myself I can say hurricanes like this aren't usually quite the same as a Tornado because their force isn't so focused as that but they carry a ton of rain and there is a lot of risk from flying debris which they will helpfully break off the trees if there isn't any laying around. That rain is a big deal because it brings flooding with it which many don't realize is blended with sewage.

Still a Category 3 storm, and still moving at only 1 mph (2 km/h). The direction has changed to 320 degrees true, though, so the forecast curve northward may have begun.

    If I have a gripe about modern day media, it's this. If you want to hook me and make me read an article, tell me what I need to know so I can decide if I want to read it. Don't try to trick me or hide the information. I miss the days where you could figure out most of the news simply by reading headlines, and just read the articles for details if you want to. And what makes me sad is even traditionally reputable publications like Time is pulling this headline shit.

        It is perfectly possible to construct a building that can withstand sustained wind speeds of 220mph. That Americans typically build houses out of match sticks and consequently blow over if you look at them (is the three little pigs not a thing in the USA) is not relevant.

          Not in Florida. Unless it's really old, it's concrete block. The termites eat wood houses pretty quickly if you aren't on top of it constantly. There are a number of trailer parks though, and for some reason they always build them in flood plains.
          • Trailer parks aren't built in flood plains for "some reason"

            They are built there because the land is cheap (because of flood plain), and the landowner can get a decent return on his space rent.

            More desirable land is too expensive for trailer parks.

            Homes being built in flood plains have to do more expensive foundation work, to get the home above the flood plain, but same rules don't apply to temporary structures, ie trailer homes.

          Yes, it is "perfectly possible". Even "Americans" know that. That it is possible is not the question.

          And what's with this suggestion that Americans don't know how to build houses? If caribbean island builders wanted to build to withstand high winds, odds are exceptionally high they would consult American architectural standards and maybe even use American-supplied solutions. You're an idiot.

          • In much of the Caribbean, steel pan-deck reinforced-concrete flat roofs are common. The main constraints are keeping the max span under 15-20 feet, and the fact that a poorly-built flat roof leaks unless it's kept meticulously sealed.

            In the US, concrete roofs are rare (though they've lately become less uncommon in new homes, partly because they also enable roof decks to compensate for a tiny yard). 10-20 years ago, they were nearly unheard of in single-family residential construction.

        First off, they never said 220 mph sustained. They said 185 sustained with gusts up to 220. And contrary to your implication, those speeds are entirely typical of what you'd measure at ground-based stations during a cat 5 storm. You seem to be unaware that buildings in hurricane zones (at least in first world nations) are designed to handle winds like those. Not only that, they routinely do so every few years.

            Yes and no. Yes, the speeds are comparable, but no, it's not at all like an F3 tornado. Hurricane winds are straight line winds that come from a single direction. Tornado winds are not straight line winds, and as such, they're significantly more dangerous. Tornados also have significantly more updrafts, making them more dangerous yet again.

    About 15 years ago, a hurricane hit Virginia near Lake Anna. A friend's dad lived on the lake, and had a number of leaning trees (but the property was owned by the power plant, who had tagged the trees but not removed them).

    They made it through the hurricane, but it stayed wet for a few days, and then we had some strong winds within the next week or so ... and the trees went down, taking other trees with them.

    I don't know if 12 hours is enough time for the water to soak in far enough to do this sort of damage, but I suspect that just loosening the top foot or so of soil with continued hurricane force winds could be enough for a lot of problems

      Depends on what kind of trees, etc.

      For example, water oaks are notorious for having shallow root systems while being incredibly tall, as well as having a tendency to rot in the middle and end up hollow in the main trunk as well as large branches.

      I've lost 3 of them over the years, but not during any of the windy blows we've had or even strong TS/cat1 'canes. The typical thing is ... we get a lot of rain over a few days or weeks, the ground is extremely soaked, the tree is already leaning a little, and there is a ton of extra water weight up in the crown/leaves. And then the ground gives way, roots rip, and the tree falls over. Usually leaves the root system perpendicular (almost) to the ground and has a nice large "wall" of the shallow roots and dirt, etc.

    • by myid ( 3783581 )

      In Florida, can you cut down the trees on your property without government interference? Where I live, you can't chop down a tree without a local government permit, and you might be required to replace the tree with a similar tree. And good luck getting the permit to chop down the tree, if an endangered-species bird has a nest in the tree.

      I hope you don't have government rules like that in Florida. Those rules would make it harder to make your property hurricane-safe.
