Mom told us of those days; of forests being torn up, of buildings tossed through the air. You are talking of teratons of tnt.
Sounds like you're describing something nearing a Cat 4 or Cat 5. It also sounds more like what you would commonly see with a tornado than a 'cane. So its possible the storm system she was seeing had some cyclones involves. Most 'cane's don't reach that level of power, so more than likely your mom was describing a handful of very very bad ones as opposed to the usual ones that may sweep through an area. If a location was hit like that monthly or more often - there'd be no one living there.
A cane's damage tends to be worse depending on where you are when it hits, and how much rain it drops. Initial damage is wind and storm surge - the ocean reaching up and trying to punch down everything in front of it. That's usually the really nasty part for folks living right there, and usually the reason why people evacuate. The buildings on their coast are about to be under an impressive amount of water and subject to flying debris. Storm surge is how last year the Outer Banks got a new island (ocean cut a long one in half).
Secondary damage comes from flooding. That's the part that can take forever to do and even a cat 1 has been known to do. When a storm just *sits* on you, raining non stop until rivers overflow, and in some spectacular cases near where I am - entire cities end up underwater for weeks. Flash flooding may be a risk as well depending on how far inland it comes, and how quickly your coast line goes mountianous.
Also remember - without the warm water of an ocean backing it, a cane fades out fast. A curved out coast line is in for it worse than a flat one. A penninsula is worse than a singular coast. And an island is just screwed.
... if you can't guess, the tagline may say I'm from Sigil. I'm in North Carolina. What 'canes don't reach out to smack Florida, are aiming for us.
For a game solution to this? You're going to want to control the storm surge the most. And that takes a collection of wizards/druids/clerics with walls of force, and you're a good way towards dealing with the most destructive aspects. A single druid keeping the winds from hitting over a certain speed over the city - and you have the other half handled. And a good city architect and planner can help them do that with most effeciency. It doesn't take as much power to simply hunker down and wait it out as you'd think.
