What is the difference between a flood watch and a warning?

A flood watch means flooding is possible. A flood warning means flooding is happening or about to. A flash flood warning is the most urgent and means move to higher ground now.

Is it safe to drive through flood water?

No. Most flood deaths happen in vehicles. As little as a foot of moving water can carry away a car, so turn around rather than drive through water of unknown depth.
