UNCW Hurricane Terminology

Classes Canceled Period of time when classes will not take place at UNCW, therefore grading and attendance policies are revoked.
Emergency Operations Center The location at UNCW where all resources and information will be routed during a hurricane emergency.
Hurricane Emergency The period of time at UNCW from when a hurricane threat is identified in the Atlantic Basin to the completion of the recovery period and all reparations of UNCW damages from the hurricane and its subsequent effects
Mandatory Evacuation An evacuation order in which students are required to leave campus for a safer location. The campus will soon close following a mandatory evacuation and all residence halls will be locked and all entrances to campus blocked.
Shelter-in-Place An emergency action where resident students will be asked to remain on campus through the hurricane emergency instead of evacuating. The students will not be allowed to leave the residence halls in this situation. A shelter-in-place scenario will rarely occur.
University Closed All business operations will cease at UNCW. No UNCW faculty, staff or students will be allowed on campus unless designated as emergency personnel. Entrances will be blocked and all services stopped until the university is once again opened. UNCW reserves the right to partially open the university for business operations and continue the cancellation of classes if necessary. This will be specified in public announcements.
University Opened Accesses to campus will open to traffic and UNCW students, faculty and staff will be allowed on campus. Business operations and education processes will resume where possible. However, classes may or may not resume at this time and residence halls may or may not remain closed. UNCW reserves the right to partially open the university for business operations and continue the cancellation of classes if necessary. This will be specified in public announcements.
Voluntary Evacuation An evacuation order given to UNCW students well before the arrival of a hurricane. Classes are officially canceled and the grading and attendance policies are revoked. Students are encouraged to leave campus for a safer location but are not required to do so.

Tropical Weather Terminology

Hurricane Tropical cyclone in which the maximum sustained surface wind speed is above 74 mph.
Hurricane Eye The calm center of the storm. In this area, winds are light and the sky is only partly covered by clouds. The eye's period of calm may only last for a short time before severe weather returns.
Hurricane Eye Wall A doughnut shaped zone of the highest winds inside a hurricane surrounding the eye.
Hurricane Season The period of time when conditions are most favorable for tropical cyclone development. Hurricane season lasts from June 1 to November 30, but hurricanes may develop outside of this timeframe.
Hurricane Warning A warning that sustained winds of 74 mph or higher and associated hurricane conditions are possible within 36 hours.
Hurricane Watch An announcement that sustained winds of 74 mph or higher and associated hurricane conditions are possible within 48 hours.
Saffir-Simpson Hurricane Wind Scale A scale used to classify hurricanes. Under this scale, hurricanes are classified as follows:

Category 1: winds of 74-95 mph (64-82 knots), storm surge 4-5 feet above normal

Category 2: winds of 96-110 mph (83-95 knots), storm surge 6-8 feet above normal

Category 3: winds of 110-130 mph (96-113 knots), storm surge 9-12 feet above normal

Category 4: winds of 131-155 mph (114-135 knots), storm surge 13-18 feet above normal

Category 5: winds of >155 mph (>135 knots), storm surge >18 feet above normal
Storm Surge An abnormal rise in sea level accompanying a hurricane or other intense storm.
Tropical Depression Tropical cyclone in which the maximum sustained surface wind speed is less than 38 mph.
Tropical Storm Tropical cyclone in which the maximum sustained surface wind speed is between 39 and 73 mph.
Tropical Storm Warning A warning that tropical storm force winds (39mph-73mph) may pose a threat to an area within 24 hours.
Tropical Storm Watch An announcement that tropical storm force winds (39mph-73mph) may pose a threat to an area within 48 hours.
