I did not even know about it until my parents called asking if I was
flooded.  We got a few drops here.  I live on the SE side of the valley
and it hit the northwest side about 20 miles from me.  It actually rolled
out of the mountains west of the valley and was dropping 5 inches an hour
up there.  It dropped 3 inches in 90 minutes, two inches of that in
twenty minutes on some neighborhoods.  Putting that in perspective we get
a little over 4 inches a year.  All the flooding was very localized where
it hit.  The flood channels seem to be handling it.  All the water drains
SE to Lake Mead.  Big flashflood warnings out there now.  More is
supposed to be on the way.  Its all thunderstorms though and could go
around or over as the mountains act on it.
