Next message: James Alexander: "Re: T&T: Storm surge question"
I guess it may be a little silly to be asking such a grade school
question in the face of the incredible challenges facing everyone who
has to deal with what Katrina left behind, but I have not so far found a
clear answer in the reading I've been doing. What exactly is a "storm
surge?" I realize it's a rapid rising of water, but what causes it? Is
it the water being piled up by a hurricane's winds? Is it a bunch of
big waves that come ashore or just a steady rise of water, like a flood
tide run amok?
I'm curious because in the photos of marinas and waterfronts, a lot of
the boats on shore appear relatively undamaged. I know photos make
things look better than they are, and the relatively wide or aerial
shots don't show any details. But instead of the splintered, smashed
hulks one might expect as a result of a boat being beaten up onto the
land by wind, many of these boats look like they were simply lifted,
moved, and then set down. Since the boats often appear to be sitting on
top of building debris, it makes me wonder if the storm surge comes
after the worst of the wind?
Anyone willing to explain what happens can contact me directly if they
like rather than take up space on the list. Thanks.
