Two recent studies show that typhoons and hurricanes are getting slower, and are expected to slow even more as the planet warms.

“Nothing good comes out of a slowing storm,” National Oceanic and Atmospheric Administration (NOAA) Center for Weather and Climate scientist James Kossin told National Geographic. “It can increase storm surge. It can increase the amount of time that structures are subjected to strong wind. And it increases rainfall.”

Kossin wrote one of the new studies, published in Nature Wednesday, which found that tropical cyclone speed had slowed by an average of 10 percent worldwide from 1949 to 2016.

Another study, led by researchers with the National Center for Atmospheric Research (NCAR) and published April 6 in the Journal of Climate, plugged 22 hurricanes from the past 13 years into climate models with temperatures up to five degrees warmer and found that the storms were on average nine percent slower and 24 percent wetter.
