The US Coast Guard airlifted at least 21 people injured on Abaco Island, which Dorian hit on Sunday with sustained winds of 185mph and gusts up to 220mph, a strength matched only by the Labor Day hurricane of 1935, before storms were named. Scientists say climate change generally has been fueling more powerful and wetter storms and the only recorded storm more powerful than Dorian was Hurricane Allen in 1980, with 190mph winds, though it did not make landfall at that strength.
