From an altitude of 230 miles, external cameras aboard the International Space Station captured video of Tropical Storm Katia at 10:03 a.m. EDT August 31, 2011, as it churned across the central Atlantic. Katia is moving west-northwest at a brisk speed of 21 miles an hour, packing winds of 65 miles an hour. Katia is expected to strengthen into a major hurricane over the Labor Day weekend, but is not an immediate threat to land.
