Sheltering in place for these warnings

To protect students, faculty, and staff at these locations, the UNCW siren will sound the alert tone for a tornado warning affecting any part of New Hanover County. The alert tone will sound every 30 minutes while the warning is active. An all-clear tone will sound when the warning is over.

You may need to shelter in place if hazardous materials have been released into the atmosphere. This precaution keeps you safe by minimizing the exposure to potentially dangerous chemicals.  This is not the same thing as sheltering from a storm.  Please monitor your official UNCW Alerts.

When the siren sounds, university officials will post information about the emergency immediately. However, depending on the nature of the emergency, it may take several minutes for information to become available. For this reason, campus community members must remain sheltered until an "all clear" has been issued.
