Here is the dire report. Now, I suppose that the second storm, due tomorrow, could happen, but if it's like the first storm, it will be like watering the lawn.
"There's going to be so much rain in just a couple of days that a lot of areas might not be able to handle that much rain," said NBC4 meteorologist Crystal Egger. "It just runs downhill like a concrete driveway."
Two storms will usher moisture into the region, moving down from Northern California Wednesday morning before bringing about a half-inch to an inch of rain to Southern California.
The heaviest rain Wednesday is expected after the evening commute and into the overnight hours. The more powerful of the two storms will arrive Thursday evening and bring up to 2 inches of rain in central and southern valleys, 2 to 4 inches in foothill areas and 6 inches of rain in some mountains.
The National Weather Service described it as the most significant storm in the last three years in Southern California, adding that thunderstorms are possible Friday and Saturday. Showers could continue into early Sunday.

The city of Glendora issued an Orange Level alert for residents in the burn area, meaning voluntary evacuations are in effect. Residents are directed to remove vehicles, trash bins and other obstructions from streets prior to evacuating.
The city's evacuation center is at the Crowther Teen & Family Center located at 241 W. Dawson Ave.
Residents who do not evacuate will be asked to sign a Refusal to Evacuate form, indicated they understand the risk involved.
"The alert level was raised to orange from yellow due to the Weather Forecasts and the field conditions within the foothills of Glendora," according to a city advisory.
The city could issue a Red Level alert, which includes mandatory evacuations."
All told, there was probably about two hours of what you'd call actual rain. So little, in fact, that there is no wetness on the street outside whatsoever.
