WASHINGTON (AP) — A meteorologist who oversaw warnings and forecasts during one of the busiest spurts of Atlantic hurricane activity on record will take over as the new director of the National Weather Service, as scientists expect extreme and dangerous storms and heatwaves to worsen with climate change.

The National Oceanic and Atmospheric Administration on Tuesday named National Hurricane Center Director Ken Graham the overall boss of the weather service, succeeding winter storm expert Louis Uccellini, who retired as of January 1.
