[californiadisasters] Re: Pineapple Express Headed To California

"Southwest California" is a puzzling description. Our local forecasts call for Northern California to get pummeled over the next several days. They're dumping water out of the reservoirs as fast as they can. I'm especially sensitive to this because I live in the North Natomas area of Sacramento, which is the bottom of a bowl surrounded by rivers and canals lined with levees of questionable strength.

Gurgle gurgle.
