In the weeks before Hurricane Harvey tore across the Gulf of Mexico and plowed into the Texas coast in August 2017, the Gulf's waters were warmer than any time on record, according to a new analysis led by the National Center for Atmospheric Research (NCAR).

These hotter-than-normal conditions supercharged the storm, fueling it with vast stores of moisture, the authors found. When it stalled near the Houston area, the resulting rains broke precipitation records and caused devastating flooding.

"We show, for the first time, that the volume of rain over land corresponds to the amount of water evaporated from the unusually warm ocean," said lead author Kevin Trenberth, an NCAR senior scientist. "As climate change continues to heat the oceans, we can expect more supercharged storms like Harvey."
