Storm information. At 10 am Hst, the center of Hurricane Iselle was located near Latitude 17.2N, longitude 145.9W, or about 625 miles East-southeast of Hilo Hawaii about 830 miles East-southeast of Honolulu Hawaii. Hurricane Iselle is moving West-northwest at 16 mph. Maximum sustained winds are near 90 mph.
Situation overview. Iselle is expected to bring heavy rains, high surf and damaging winds. Hurricane conditions are expected on the Big Island of Hawaii on Thursday. Tropical Storm conditions are expected to spread to Maui County Thursday night and possibly to Oahu on Friday. Swells generated by Iselle are expected to reach the main Hawaiian Islands today, possibly becoming damaging along some coastlines starting late tonight or Thursday. High Surf is expected to reach the islands ahead of the heavy rains and strong winds. The high surf may bring coastal flooding, particularly when combined with afternoon astronomical high tides.
While there is still some uncertainty in the exact track and strength of Iselle, the Big Island and Maui are expected to be impacted first. The rest of the state remains at risk to experience the impacts of Iselle.
The next local statement will be issued around 12:30 pm Hst, or sooner if conditions warrant.
Hurricane Warning In Effect.
For those under a warning, your preparations to protect life and property should be rushed to completion. In a tropical cyclone, conditions can change quickly. Evacuate if directed to do so by local officials, or if your home is vulnerable to high winds or flooding. Cancel any beach activities until further notice. Persons living near the shore should be prepared to evacuate quickly should building surf threaten.
For those under a watch, now is the time to prepare. Do not wait until it is too late. Stay calm and keep informed. Closely monitor NOAA weather radio or other local news outlets for official storm information. Listen for warnings or changes to the forecast.
It is vital that you do not focus on the exact forecast track. Forecast movement, direction, and speed are only estimates. Even small errors in the forecast track can mean major differences in where the worst conditions will occur. Damaging effects can extend far from the center.
Be Ready to evacuate if necessary. Heed the advice of local officials and comply with any orders that are issued. Persons living near the shore should be prepared to evacuate quickly should building surf threaten.
At ports, docks, and marinas, perform the prescribed preparations according to your emergency operations plan.
If you live on a boat, begin to safely secure your craft and make plans to leave it for adequate land based shelter.
Small Craft should return to port or seek Safe Harbor.
