That’s Galveston Island going for a dip in the before-and-after captures above, from a set of interactive timelapse maps released by the Texas Tribune and ProPublica yesterday (along with several articles by authors Kiah Collier and Neena Satija). The new maps model flooding across the Houston region during Hurricane Ike — as well as what would have happened if Ike had actually hit just south of Houston, as meteorologists initially expected.
The maps are your chance to relive an old disaster, or to see how many of your neighbors you can take out with a hypothetical-but-not-unrealistic future storm: users can pick between Ike, south-er Ike, a storm 15% stronger than Ike (nicknamed Mighty Ike), and a modeled 500-year storm (which the article suggests may actually be a concern on the every-few-decades-or-so level; ‘500-year’ has always meant ‘a low probability in any year’, and climate change is shaking up old modeling assumptions). The graphics also include a few dramatic face-offs:Â Mighty Ike and the 500-year storm VS. 2 of the miles-long multi-billion-dollar coastal protection projects being studied for the upper Texas coast.
You can even search for your home address in the map system to see what flood levels might look like in your own back yard. Here’s what the maps show happening to the Clear Lake, Seabrook, and League City areas at the peak of the 500-year storm model’s storm surge, which the article says is a “not if, but when” event:
