HURCON

Hurricane Condition (HURCON) is an alert scale used by the United States Armed Forces, primarily the United States Air Force, 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. A HURCON will typically be issued 72 hours or longer before a hurricane is expected to strike the installation.

As of 2015, USAF bases use the Tropical Cyclone Condition of Readiness (TC-COR) scale for HURCON instead of the older 4 condition scale. The historic scale consisted of 4 conditions, from Secure to Alert. 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.

Condition 4: Alert phase
Hurricane Condition 4 was declared by the Base commander when the forecast called for the arrival of a tropical storm with 50-knot (58 mph) sustained winds or greater within 72 hours. Stock up emergency supplies. Copy important papers and phone numbers; store in storm-proof place. Individuals evacuating should decide where to go.

Condition 3: Preparation Phase
Hurricane Condition 3 was declared by the Base commander when the forecast called for the arrival of a tropical storm with 50-knot (58 mph) sustained winds or greater within 48 hours. Monitor storm reports on local radio and television stations. Bring in lawn furniture, trash cans, potted plants and other loose objects. Individuals planning to evacuate should know the route they will take and consider leaving before an evacuation order is issued.

Condition 2: Final Preparation Phase
Hurricane Condition 2 was declared by the Base commander when the forecast called for the arrival of a tropical storm with 50-knot (58 mph) sustained winds or greater within 24 hours. Adhere to evacuation orders if provided. Listen constantly to storm reports and board windows and glass doors. Turn refrigerator and freezer to their highest setting; freeze water in jugs. Fill sinks and tubs with water for bathing and sanitary purposes. Residents on high ground away from beaches should consider riding out the storm.

Condition 1: Secure Phase
Hurricane Condition 1 was declared by the Base commander when the forecast called for the arrival of a tropical storm with 50-knot (58 mph) sustained winds or greater within 12 hours. All preparations should be completed. If necessary, evacuation orders should be followed. Remain indoors if riding out the storm.
