Growing evidence links warmer oceans to more rapid intensification, as when Hurricane Polo gained 110 mph in 24 hours.

Rapid intensification - there's growing evidence linking warmer ocean heat content to an increased frequency of rapid intensification events (24-hour intensity jumps).¹NOAA GFDL, "Global Warming and Hurricanes," gfdl.noaa.gov, November 2024. https://www.gfdl.noaa.gov/global-warming-and-hurricanes/ Example is Hurricane Polo (Eastern Pacific, September 2026) with a 24-hour wind speed increase from 50 mph to 160 mph, an increase of 110 mph.²NOAA National Hurricane Center, "Tropical Storm Polo Intermediate Advisory Number 3A (600 AM CST Mon Sep 21 2026)," nhc.noaa.gov, September 2026. https://www.nhc.noaa.gov/archive/2026/ep17/ep172026.public_a.003.shtml³NOAA National Hurricane Center, "Hurricane Polo Intermediate Advisory Number 7A (600 AM CST Tue Sep 22 2026)," nhc.noaa.gov, September 2026. https://www.nhc.noaa.gov/archive/2026/ep17/ep172026.public_a.007.shtml
