A tornado is a violently rotating column of air extending from a thunderstorm to the ground. The average tornado moves from southwest to northeast, but tornadoes have been known to move in any direction. The average forward speed of a tornado is 30 mph, but may vary from almost stationary to 70 mph.
In the southern states, peak tornado occurrence is March through May. Most tornadoes that affect the UNCW area are F0 or F1. Tornadoes in our area are most likely to develop from tropical storms and hurricanes that affect New Hanover County.
The local National Weather Service office is the only entity legally allowed to issue a tornado watch or warning.

During a tornado warning:
A tornado is sighted or indicated on radar approaching the campus
- If time permits, go to the interior hallway on the lowest floor.
- If time does not permit, go to the safest area of your classroom or office (an inside wall) furthest away from the doors and windows.
- Avoid windows, or areas with wide, free-span roofs. A special note for Trask: Move out of the arena area into a side corridor with no windows, or into a restroom.
- Take shelter underneath a desk or any heavy furniture available.
- Assume a curled position to protect your head
- All qualified personnel should render first aid.
- If you are in a modular unit:
Evacuate the modular unit immediately and take shelter in the closest safe building. When safely within a building that is not a modular unit, take shelter in an interior room of the building on the lower floor, if time permits.
After a tornado
- Continue to pay attention to National Weather Service warnings and watches as severe weather may continue.
- Use caution when traveling on campus and avoid debris.
- Report any severe damages to University Police.
When a tornado warning is issued for New Hanover County, or signs of a tornado are seen/heard by UNCW emergency personnel, the outdoor siren system will be activated and the UNCW community will be notified of the warning through UNCW Alert.
