If the weather cooperates, a rocket carrying a top secret military payload will lift off from the Central Coast tomorrow.
A Delta Four rocket is set to lift off from Vandenberg Air Force Base just before 11 tomorrow morning.
The payload is reported to be a satellite for the National Reconnaissance Office.
The launch team is concerned about the potential for cloud cover which could force a delay in the launch.
The forecast calls for a 30% chance of clouds.
Jalama Beach will be closed to the public starting at 8 a.m. tomorrow, as a precaution during the launch window.
The beach closure is set for 8 a.m. until noon.
