Anon in SoCal here, still thinking about the possible Long Beach pride thing, looked up where it is, and its on the coast, close to where that anon who gave the warning took the photo. Also, the parade is today at 9:30 am Pacific Coast time, but thats the preshow and the "step off" time is at 10:30 am. Odds are thats when we should be watching and praying nothing happens.
Prado would flood most of Orange County by the looks of it, lots of people have been stirred up worried about it lately.
okay, Prado is on the river marked over Santa Ana. Long Beach Is to the north, on the other side of the river to the left of Santa Ana
Honestly, The dam up in Big Bear is the only one i havent heard about in regards to failure.
