Hurricane Iselle Aims at Hawaii

Hurricane Iselle unexpectedly strengthened earlier today and is now a Category 1 hurricane with maximum sustained winds at 90 MPH. Based on this increase in organization Iselle is now expected to impact the Big Island in Hawaii as a hurricane which includes Hilo. As of the latest advisory from the Central Pacific Hurricane Center the island of Oahu including Honolulu is under a Tropical Storm Watch.

In addition to the potential for destructive winds and a minor storm surge Iselle is going to produce life-threatening flash flooding in parts of Hawaii. Flights coming/going from the mainland into Hawaii will undoubtedly be impacted tomorrow.

The last hurricane to make direct landfall in Hawaii was Hurricane Fernanda back in August of 1993. Many other storms have skirted the islands but none have made landfall as a hurricane.
