Southern California Operational Weather Briefing Package
This briefing package is assembled automatically every 15 minutes.
It is designed to be a "first look" weather briefing for any California
aircraft operations and for search and rescue (SAR) air and ground missions.
Be aware the script that builds this package just assembles what's there.
It doesn't know whether or not what it puts in the file is what's really
supposed to go there. It just does what it's told to do. The data may
not always be the most current. Pay attention to the valid times.
