  1. While there is still a lot of uncertainty with regards to where Sandy will come ashore late this weekend/early next week...there are things you can do now to begin preparing for potential impacts.
    Our latest forecast models continue to indicate that Sandy will impact the northeast early next week, including our area. We want to stress that now is the time to monitor and prepare for these possibilities, but not panic. We are still many days away from the storm. To help you prepare we have some suggestions on this graphic on what you can do. Please share this information with others.

  3. Offshore winds will bring a critical fire weather threat to the coastal ranges and foothills of southern California, including the metro areas of San Diego and Los Angeles.
    Surface high pressure building over the Great Basin will bring gusty offshore winds Thursday evening through Friday night. Areas in the High Wind Warning will see northeast winds increase to 30 to 40 mph Thursday evening in the favored pass...
