Water, Water, Everywhere
As Hurricane Florence approaches the Carolinas this week, forecasters and disaster management officials are stressing one key piece of advice to evacuating residents: Take the storm seriously, regardless of the category designation. Once projected to hit Category 4, Florence was at Category 2 as of Thursday morning, but that number only describes the wind speed. Meanwhile, as University of California-Irvine civil engineer Amir AghaKouchak notes, there could be unusually devastating flooding, as storm surge from the ocean meets rainfall from a storm that is projected to pour on the region for days.
“Compound flooding” is the phenomenon that left Houston under water after Hurricane Harvey in 2017, and, at its worse, could cause rivers to run in reverse. And, AghaKouchak says, climate change and sea level rise both make such flooding more likely in storms such as Florence.
AghaKouchak talks to Ira about flooding, Florence, and the factors that could shift the storm favorably or unfavorably in the coming days.
