New topographic and predictive rainfall data means more people in Harris County will be mapped in floodplains.

When Hurricane Harvey left so much of Houston underwater, it highlighted a problem that’s been getting worse for years: Harris County’s existing floodplain maps just don’t work.

In the year since the historic storm, flood control officials have promised to change that, and they already had plans to redo the maps, but new data on the geography of the area and the amount of rainfall forecasters expect in the future means the new maps could look drastically different.

It’s crucial the maps are done right, as people are using the maps, meant to set flood insurance premiums, for more than they are intended . . . 

The flood maps don’t factor in sea level rise or changes in extreme weather, and many are years out of date. In Mexico Beach, 'minimal-risk' homes were swept away.

The official map laid it out for more than 200 homes within the community of Mexico Beach, Florida: the federal government had characterized their flooding risks as minimal, despite their near-beachfront locations.

That meant for them there were no requirements to buy flood insurance, and local residents say many did not.

When Hurricane Michael and its 155-mile-per-hour winds slammed into the town on Oct. 10, with a storm surge of perhaps 19 feet, the result was devastation. An analysis by coastal geologists from Western Carolina University has found that 70 percent of the homes were demolished. Another 10 percent were severely damaged.

The sleeping giant may be about to awaken.

Hurricane activity in the Atlantic Ocean, Caribbean Sea and Gulf of Mexico is forecast to ramp up over the next couple of weeks. "Weather models have flipped the switch on the Atlantic hurricane season and see multiple areas of development possible, starting mainly this weekend," weather.us meteorologist Ryan Maue said.
