Whenever a hurricane threatens land, almost all of the focus is on preparing for the strong winds. It’s not always the wind that gets you—it’s the water. The storm surge in a hurricane is arguably the greatest threat with these landfalling terrors, and it’s one that too many people seem to ignore until it’s too late.

Andrea Thompson over at Climate Central has a great read on how the National Hurricane Center developed a new product to better convey the risk that storm surge poses to land ahead of a landfalling tropical system. The new storm surge maps are in place for use this hurricane season.
