Statement from Gov. Abercombie’s Office

Hurricane Iselle is a Category Four tropical cyclone tracking 1,190 miles east of Hilo. The National Weather Service (NWS) has not issued any watches or warnings for Iselle at this time, but has advised the Hawaii Emergency Management Agency (HI-EMA), formerly known as State Civil Defense, and county civil defense and emergency management agencies of the potential for Iselle to make landfall in the Hawaiian Islands.

“It is likely Iselle will impact the islands sometime Thursday afternoon and will leave the state late Friday to early Saturday,” said Doug Mayne, Administrator for Emergency Management. “Although the system should weaken according to forecasts, we recommend residents and visitors stay cautious and monitor local news stations.”

Recommended preparedness actions for tropical cyclone are:

1. Have a reliable way to get information (e.g., sign up for local notification systems and get a battery or crank-operated radio). Information on local emergency notification systems can be found at:

• Kauai – www.kauai.gov
• Oahu – www.nixle.com
• Maui – www.co.maui.hi.us/list.aspx
• Hawaii Island – Email civildefense@hawaiicounty.gov and request enrollment to the emergency notification system. Include your mobile phone number.

2. Review or create emergency plans that detail how to communicate with your family and friends in emergencies as well as where to go if asked to evacuate.

3. Put together or check your emergency supply kit. This kit should have seven days of food and water. Visit www.scd.hawaii.gov for a checklist. You should also have a smaller evacuation bag with changes of clothing, sturdy shoes, and copies of your identification and important documents.

4. Prepare your home for possible high winds or locate the three hurricane evacuation shelters closest to you.

5. Monitor local news broadcasts for the latest information.
