Civil Defense

Hawaii's State Civil Defense agency has developed a warning system to alert the public of an emergency. If you hear Civil Defense sirens (a steady siren tone for 3 minutes and repeated if necessary), listen to your car radio, turn on the television or ask hotel personnel for emergency instructions. Please note that civil defense sirens are routinely tested at 11:45 am on the first working day of each month.

In addition to state and county civil defense agencies and other emergency responders, visitors staying in hotel properties will be provided with information on what to do during various crisis situations. Emergency procedures for your respective hotel can be found in the back of the information compendium in your guest room. Please take a moment to review this important information.

Emergency Shelters

In the case of a severe emergency, such as a hurricane, the Civil Defense warnings on the radio and television stations may advise you to evacuate further inland, to higher ground or to an emergency shelter. These shelters are located primarily at schools and parks. It's important to note that shelters do not stock supplies, so if possible, bring food, water, clothing, blankets, medicines and other necessities.
