    That email went out at 7.30 pm. I received a flash flood warning on my phone… 3 hours later.

      The alert as part of this story was a WATCH. The alert that came through later tonight (I saw it on my phone as well) was a WARNING.

      The watch (usually announced prior to the actual weather event) means conditions are favorable for the event to occur. The warning means it’s already occuring or is definitely going to occur. Warnings are way more serious than watches.
