By -
1pm MST updated flash flood risk forecast until 7a Sunday.
Be especially vigilant in the yellow and red areas. The red area (greatest danger) includes Phoenix, Tucson and Flagstaff. 

-- original posting -- 
Radar at 10:45am MST/11:45a MDT

National Weather Service says, 

Normally dry washes will quickly flash flood with relatively low amounts of precipitation, and many creeks remain elevated well above normal levels. Burn scars and metropolitian areas should be close attention to flood potential, as well. 

Three-day rainfalls to 11a MDT exceeded six inches in a few spots (below).


Radar (below) and other meteorological data as of 11:30a MST indicates things should be relatively quiet for another hour or two in Arizona. Then, widespread thunderstorms should develop with heavy to torrential rains. 

In New Mexico, thunderstorms are developing rapidly west of Albuquerque due to a westward-moving low pressure system. 

Please monitor local sources of weather information the rest of today.

The brown area has a significant risk of tornadoes. Remember: if a tornado warning is issued, go to your basement and get under heavy furniture like a pool table. Of, if your basement is finished, get into the bathroom. Go ahead an put a couple of water bottles and, if appropriate, diapers in your shelter area. Wear shoes.  If you don't have a basement or safe room, go to the lowest floor and get into a bath or closet in the middle of your home. Children should be put in the bathtub.  I'll update later today.

Pink is a winter storm warning for significant icing. Deep green is a winter storm watch. I don't know why this is still a watch. If I were on the forecast desk I would have a winter storm warning for icing.  Dark blue is a winter weather advisory, a lesser condition, for icing.  Here is a view of the entire watch/warning/advisory area.

Power outages may occur in this areas. Deep blue i...
