WASHINGTON (AP) — Tropical cyclones around the world are moving slightly slower over land and water, dumping more rain as they stall, just as Hurricane Harvey did last year, a new study found.

This isn't about how powerful a storm's winds are, just how fast it chugs along. Storms in the last few years — before 2017's Harvey — were moving about 10 percent slower globally than in the late 1940s and 1950s, according to a study published in Nature Wednesday. Storms worldwide in 2016 moved about 1.25 mph (2 kph) slower than 60 some years ago.
