In Austin TX the most likely problem is flooding, and people who don't believe just how high the water can get. I always show newcomers the picture of the lower field at my weekend cabin NW of town - the pic that shows the lower field flooded - the field that is SIXTY (60) feet above the river.

In Houston, where I used to live on the coast, hurricanes were the obvious problem, with people overreacting to small category 1 or 2 storms, or underreacting to bigger storms.

And newcomers: a cousin visiting Saturday commented that he'd been in NYC during a hurricane and "it's like a big thunderstorm!" Um, no.
