I have heard from two sources, but have been unable to confirm, that because of the emergency situation in San Diego County, the Supreme Court issued the following statement at some point yesterday:
Pursuant to the Order of Chief Justice Ronald M. George, Chair of the California Judicial Council, October 22, 2007 and October 23, 2007 are deemed holidays for purposes of computing the time for filing papers with the Court and for purposes of computing time under Title 8 of the California Rules of Court.
Again, I have not confirmed this and cannot find such an order online. I have also heard that the San Diego County Superior Court was closed yesterday and is also closed today. If you are down in the San Diego area, stay safe.
UPDATE: Here is a copy of what may be the order in pdf format. It is available at the web page of the Court of Appeal for the Fourth Appellate District, Division One. It appears that the order may apply only to filing deadlines within that Court of Appeal.
