TCCOR 1 Emergency: Actual winds of 50 knots or greater.
All outside activity is prohibited.

TCCOR 1 Recovery: Destructive winds of 50 knots are no longer occurring. Actual winds are 34-49 knots.
Nonessential functions remain closed unless directed by the commander. All but emergency essential personnel remain in their quarters.

Storm Watch: The winds are not forecast to exceed 50 knots sustained (the criteria for "destructive winds") but still exists a probability of high winds due to the proximity of the storm. High winds may include gusts exceeding 50 knots and/or sustained winds meeting TCCOR 1 Caution criteria. The storm is also close enough to the area that a heightened alert status is necessary in order to rapidly establish elevated TCCOR conditions should the storm deviate from the forecast track. Personnel should follow Standard Operating Procedures for TCCOR Storm Watch and stay alert for any changes to TCCOR status. In some instances, it may be necessary to return to TCCOR Storm Watch from another TCCOR level if the storm is not currently forecast to impact the area, but is in close enough proximity that should it change course, it could likely impact the area.
All military and civilian personnel will return to work within 2 hours or at normal duty hours unless otherwise instructed by their commander. The Commissary and BX will resume operations, unless directed otherwise by the installation commander.

All Clear: Hazardous conditions and winds are no longer present. Return to normal duties. All Clear is announced when all hazards have been cleared.
DoDDS teachers, staff and students will return to school during normal hours. From June 1st to November 30th Okinawa will return to TCCOR 4.

NOTE: The wind speeds shown above for each TCCOR serve as a guide for decision making. The final decision on TCCOR declaration rests with the Commander, 18th Wing based on wind speed, weather forecast, safety and operational and mission concerns.
