Last Update of the Night

National Weather Service is now calling for "life-threatening flash flooding the rest of the night in the area outlined in green. Radar image 11:07p. Updated info as of 11:30p is below.
The small low pressure system will move north during the night and help cause torrential rainfall and wind gusts to 50-55 mph with scattered power outages (13,000 homes without power currently, 11:11pm). The rest of the original discussion is valid. Please see below for more information. 

--- original post updated at 11:30p ---
More than 10" has fallen near Davie in the past 48 hours ending at 10pm. 

Addition: rainfall to 11pm
There are now two areas of 10" in eastern Broward County.

As of 11:27pm, here is the radar. 
The green polygons are flash flood warnings. There is a small low pressure system over far south Florida that is moving north and will cause rains to increase to torrential levels in its path. The low is also causing the pressure to fall very quickly which is causing localized strong wind gusts. Winds gusting to 51 mph have been reported at two south Florida airports in the past hour. Sixteen thousand homes are without power. That number will likely rise. 

As of 11p: An additional 6 to 11 inches are possible by noon Thursday.
Regardless of the exact amounts, severe flooding is possible overnight. Please make sure your weather radio and/or smartphone with WEA activated during the night.

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.

It may be a bit too large but, when it comes to freezing rain and slick roads, caution is usually the better course of action.  Here's a color code: Deep purple is an ice storm warning; serious condition where power outages are possible. 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. The small area of green in Illinois is for flooding and, in Nebraska, for snow.  Here is a forecast of freezing rain amounts; totals to 6am Tuesday.  Color codes: Yellow is 0.25 to 0.50 inches. Power outages may occur in this areas. Deep blue i...
