It is unusual to have lighting with these winds storms but the yellow and orange symbols are just that.

Eastside Fire

Here's the flood forecast for the next seven days. 
The diagonal lines are where "limited" (NWS's word) flooding is forecast to occur starting Thursday. The dark blue area is where "considerable" flooding is likely starting Wednesday night into at least Friday. In fact, there is a "high" risk of flash flooding in the same area.

It is vitally important that people in the forecast flood area -- especially in Northern California -- prepare for this event. 

Via WeatherBell, here's the NWS's forecast of rainfall amounts in the dark blue area.

Taking a wider view of things, here's a view of forecast rainfall from British Columbia to Los Angeles. 
Of course, I will continue to update as this excessive rainfall and flood situation develops. Cliff Mass is also providing great information.

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.

Note: An Updated Forecast is Available HERE Freezing Rain The National Weather Service has now issued winter weather advisories, two warnings and a watch. 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 is 0.1 to .25 inc
