When a hurricane's steering winds collapse, the storm can sit in place for days, turning a wind event into a flood catastrophe. Here's why it happens.

The number the National Hurricane Center assigns a storm measures wind, and only wind. History's deadliest hurricanes prove that isn't the same as knowing how dangerous one will be.

Six to seven inches of rain in hours killed at least four people and forced dozens of water rescues across central Kentucky.

The system may or may not earn a name. The flooding threat from the Texas coast into the Deep South is already here, the hurricane center says.

With a disturbance brewing in the Gulf and rain already falling, Texas shifted its emergency operation to round-the-clock footing ahead of the worst of the week.
