Sally has winds of 150 km / h and promises to reach the Gulf of Mexico coast early this Tuesday as an intense category 2 hurricane. The most difficult thing about this large hurricane is its slow movement.
That means it will rain longer over the same area, which in eastern Louisiana is land below sea level.
The wind is not the biggest threat, but the rain and storm surge.
Now both the Alabama coast, Mississippi and Louisiana must follow the advance of this dangerous tropical system.
