Hurricane Sally is approaching the US Gulf Coast, which could trigger potentially deadly flash floods, forecasters warn.

Life-threatening flooding is likely in parts of the northern coast of the Gulf, warned the National Hurricane Center in Miami. Sally is expected to become a dangerous hurricane when it reaches the coast, forecasters warn.

Nearly 75,000 homes in Alabama and Florida are already de-energized.

Sally is one of five tropical cyclones in the Atlantic Ocean. According to meteorologists, this phenomenon was recorded only once, in September 1971.
