HURCON
# HURCON

Hurricane Condition (HURCON) is an alert scale used by the United States Armed Forces in the North Atlantic and the North Pacific to indicate the state of emergency or preparedness for an approaching hurricane. This designation is especially important to installations in the southern Atlantic region, as it is most affected by hurricanes. In the western Pacific, where hurricanes are referred to as typhoons, the scale is called Tropical Cyclone Condition of Readiness (TCCOR). A HURCON or TCCOR can be issued up to 96 hours before a hurricane is expected to strike the installation.

## HURCON conditions

As of 2021, the scale - which has been updated several times, and has minor variations between different military bases - consists of 5 levels, from HURCON 5 to HURCON 1, with three additional sub-levels for HURCON 1. As with civilian alerts, buildings may be boarded up and personnel evacuated. In addition; aircraft, ships, equipment, and other assets will be relocated, tied down, bunkered, or otherwise secured. The contraction was chosen in line with other military terminology in use like DEFCON and FPCON to communicate hazardous conditions.

| HURCON | Hours | Criteria | Instructions |

| 1C | 0 | Caution: Winds of 40-57 mph sustained are occurring. | All outside activity is prohibited. Remain in shelter until released by proper officials. If not sheltered, find shelter immediately. |
| 1E | 0 | Emergency: Winds of 58 mph sustained and/or gusts of 69 mph or greater are occurring. | Remain in shelter until released by proper officials. |
| 1R | 1R | Recovery: Surface winds in excess of 58 mph are no longer occurring and storm has passed. | Non-essential functions remain closed unless directed otherwise by the wing commander. All but emergency personnel remain in quarters until further notice. If evacuated do not return to base until directed to do so. |

## TCCOR conditions

As of 2021, TCCOR consists of TCCOR 5 to TCCOR 1, three additional sub-levels for TCCOR 1, TCCOR Storm Watch, and TCCOR All Clear.

| TCCOR | Hours | Criteria | Instructions |
| - | - | - | - |
| 5 | 96 | Destructive winds are possible within 96 hours. Only used outside of the typical typhoon season; from December 1 to May 31. | Review all other TCCOR level actions. |
| 4 | 72 | Destructive sustained winds of 50 knots or greater possible within 72 hours. Lowest level of alert during the typhoon season (June 1-November 30) | Stock up and maintain 72 hours' worth of food, bottled water, dry milk, batteries, flashlights, candles and other emergency supplies. |

| 1R | 1R | Recovery: Destructive winds have subsided and are no longer forecast to occur. | Survey and work crews are sent out to determine the extent of damage and to establish safe zones around hazards (e.g., downed power lines, unstable structures). All outside activities are prohibited. Essential base recovery is occurring. |
| Storm Watch | Storm Watch | Strong winds are possibly due to proximity of a tropical cyclone. | Monitor for changes in TCCOR and services closure information. |
