Tropical Cyclone Conditions of Readiness (TCCOR) Definitions and Responses
TCCOR 5: Destructive winds are possible within 96 hours. (Only used outside of established typhoon season)
Stock up on food, water, and emergency supplies.
TCCOR 4: Destructive winds are possible within 72 hours. (1 June to 30 November)
Stock up on food, water, and emergency supplies.
TCCOR 3: Destructive winds are possible within 48 hours.
Initiate preparatory actions such as performing general cleanup around homes and facilities, obtaining appropriate food and water supplies, checking emergency kits, and filling vehicles with fuel. (A detailed list of actions and emergency kit items may be found on the Kadena Air Base Website)
TCCOR 2: Destructive winds anticipated within 24 hours.
Remove or secure all outside items around homes and facilities.
TCCOR 1: Destructive winds anticipated within 12 hours.
No school for DoDDS students. Students will return home or remain at home. Fill containers and bathtubs for emergency water use. Make a final check of food and emergency supplies. If you live in low lying quarters, make arrangements to stay with a friend.
TCCOR 1 Caution: Winds of 35-49 knots sustained are occurring at a particular installation.
All outdoor activities, except those in direct support of urgent military missions, will be discontinued. All non-emergency essential personnel will be released to quarters and will remain indoors. DoDDS teachers and staff will return home. Schools and base facilities/services, such as the Commissary and AAFES facilities, will close at this time. Personnel should remain alert and monitor radio, television, or internet for updates.
TCCOR 1 Emergency: Winds of 50 knots sustained or gust factors of 60 knots or greater are occurring at a particular installation.
All personnel will stay indoors away from windows. Outdoor movement will be restricted to lifesaving response actions.
TCCOR 1 Recovery: After the passage of a tropical cyclone, when destructive winds have subsided and are no longer forecasted to occur, survey and work crews are sent out to determine the extent of the damage and to establish safe zones around hazards (e.g. downed power lines, unstable structures). Until the recovery process is declared complete (TCCOR All Clear), or the risk of injury and/or damage to personnel and property has been mitigated to a safe level, the general base population would normally be asked to remain indoors. In some instances, it may be necessary to return to TCCOR Storm Watch from this TCCOR level if the storm is not currently forecast to return to the area, but is in close enough proximity that should it change course, it could likely impact the area again.
All non-emergency essential personnel will remain indoors while damage assessment and cleanup is accomplished.
TCCOR Storm Watch: The winds are not forecast to exceed 50 knots sustained (the criteria for “destructive winds”) but there 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.
Personnel should remain alert and monitor radio, television, or internet for rapid changes. If high wind conditions exist, personnel may need to secure outside items and should exercise caution while outdoors, but are recommended to remain indoors if possible.
If TCCOR Storm Watch is called prior to storm passage, all military and civilian personnel will remain at work unless directed otherwise by their unit commander. Schools and base facilities/services, such as the Commissary and AAFES facilities, will remain open unless directed otherwise.
If TCCOR Storm Watch is called after storm passage, all military and civilian personnel will return to work within 2 hours or as directed by their unit commander. Base facilities and services will reopen unless directed otherwise. Schools will remain closed for DoDDS students if SW has been preceded by a condition in which students would not have attended school. However, teachers and staff return to work within 2 hours or as directed.
TCCOR All Clear: The storm is over and not forecast to return, and recovery efforts are considered complete by the Installation Commander.
Resume normal activities. Begin general cleanup around homes and facilities. DoDDS students, teachers, and staff return to school during normal hours. Base facilities and services, such as the Commissary and AAFES facilities, will reopen. From 1 June to 30 November Okinawa will revert back to TCCOR 4.
*Destructive Winds: Winds of 50 knots sustained or gust factors of 60 knots or greater.
*High Winds: Winds less than 50 knots sustained, but may include gusts exceeding 50 knots.
