Hurricane forecasts have vastly improved in recent decades, but that doesn’t necessarily mean communities are more prepared. Death tolls are rising as climate change supercharges storms and coastal areas’ populations increase. As I report today, the key to reducing hurricane damages and deaths may mean building smarter — and potentially building less — in high-risk areas. “The battle is won months and years in advance of a storm,” said Lee Mayfield, director of response at the disaster preparation firm Hagerty Consulting. “Investments in critical infrastructure, investments in hardening your home.” It’s a sharp reminder after Hurricane Beryl’s record-breaking rampage across the Caribbean and through the Gulf of Mexico to the Texas coast. In June, Beryl became the earliest Category 4 hurricane on record in the Atlantic — and then, this month, it grew to a monster Category 5. It made landfall near Houston early Monday morning as a Category 1, bringing intense winds and rains, flash floods, and storm surge as high as 7 feet. More than 2 million people were experiencing power outages in Texas as of this morning. And at least 3 people have died as a result of the storm. Experts say coastal areas need stronger building codes and more climate-resilient infrastructure. That may also mean encouraging less development in hurricane-prone areas. Half the battle Hurricane-chasing planes, satellites, data-collecting instruments and computer models have helped scientists hone their predictions for hurricane movements and intensity. The National Oceanic and Atmospheric Administration has reduced hurricane track error by 64 percent and intensity error by half since 2000, according to National Weather Service Director Ken Graham. That has helped emergency managers improve communication and tailor evacuation notices as hurricanes approach. But coastal populations have increased by more than 40 million people since 1970, according to NOAA, putting more people in the potential path of strengthening hurricanes. A study last year found that hurricane-related mortalities are often higher than official counts, which only include deaths caused by winds or rains. Many people die, for example, from heat exposure after power outages knock out their air conditioning or from preexisting health conditions exacerbated by the stress of a hurricane. And death tolls are higher for socially vulnerable populations, including people of color and low-income communities, according to the study. Meanwhile, billion-dollar climate disasters are on the rise. The costliest events: hurricanes, racking up more than $1.3 trillion since 1980.
