This is the best resource I have found. It is a blog from the San Diego Union-Tribune, giving a status of all of the areas and official evacuation notices. I posted the latest stuff mentioning Chula Vista, below. Mira Mesa High School is one of the shelters for evacuees, so it is probably safe (for now).
