Helene and the mountains that drowned

In the late hours of 26 September, Hurricane Helene made landfall on the Florida Gulf Coast, near the town of Perry, as a category-four storm with winds of 140 miles an hour, and then did the thing that distinguishes the hurricanes of this era from the ones the country learned to fear: it kept going. Instead of dying against the coast, Helene carried its energy inland, across Georgia and into the mountains of the Carolinas and Tennessee, and in the Appalachian valleys it delivered the rain that turned creeks into torrents and torrents into walls of water, destroying roads, bridges, houses and, in the end, more than two hundred lives. The disaster killed more Americans than any hurricane since Katrina in 2005, and most of them died in the mountains, not at the sea.

The geography of the catastrophe is the lesson of it. Western North Carolina is a region of steep slopes and narrow valleys, a landscape that gathers water with an efficiency beautiful in normal times and fatal in flood times; the rain Helene delivered, in places more than two feet in seventy-two hours, ran down the slopes and arrived in the valleys as a surge measured in vertical feet. The town of Chimney Rock was effectively destroyed, its main street buried; Asheville, a city of ninety thousand that sits in a bowl of mountains and had advertised itself as climate-proof, lost its water system, its roads and its connection to the outside world for days, and the rescue crews that reached it described the landscape as unrecognisable. The mountain region, which had watched coastal hurricanes on television with the complacency of distance, discovered that the mountains are not a refuge from these storms but a trap for them.

The human toll is the part the statistics cannot hold. The dead include an infant carried from its mother’s arms by the flood and families found in the debris of houses that had stood for generations, and the count, which passed two hundred and kept climbing, will not be final for months. The rescue teams worked through the mud knowing that each day reduced the chances of finding the missing alive; the helicopters flew where the roads were gone; and the mountain towns, proud of their self-sufficiency, learned that self-sufficiency has limits measured in feet of water. The images that emerged, the destroyed bridges, the houses resting on their sides in the riverbeds, will define the autumn as no other news can.

The political response arrived with the storm. President Biden declared a major disaster and visited the region, the governors of the affected states coordinated with an efficiency that belied the national argument, and the former president used a trip to Georgia within days to attack the administration’s response and repeat claims about FEMA’s finances that federal officials described as false. The disaster relief will become one more front in the election argument, and the argument will obscure the thing the storm demonstrated: that the federal system of disaster response, built for the hurricanes of the last century, is being asked to handle storms that no longer behave like them. The flooding was not a coastal event that wandered inland; it was the new climate, in which the heat of the ocean and the air arm the storms with more water than the country’s infrastructure was designed to carry.

The recovery will take years. The towns of the Appalachians that Helene destroyed were not wealthy; they were the small communities, the tourist economies, the old houses, the people for whom rebuilding is not a question of insurance but of survival. The storm has gone, and the season continues, and the questions it raised will be argued while the debris is cleared. The mountains that drowned have been added to the map of the disasters that define this century, and the map, unlike the houses, cannot be rebuilt.
