Check Six: Hurricane Iwa – 36 years ago

This map shows the track of Iwa and location during the period of its highest intensity near Kauai. Click on photograph to enlarge.

Iwa begun developing as a low pressure trough near the equator in early November 1982. Slowly, it begun to gain strength and to move northeastward. Early in the day on November 19, it had organized into a tropical storm but later that same day – as it moved over warmer waters (partially because it was an El Nino year) – it gained strength and reached Category 1 hurricane status on the Saffir-Simpson Hurricane Scale (SSHS). At that time it was about 500 miles southwest of Hilo, Hawaii.

Iwa continued moving in a northeastward direction towards Kauai. On November 23, its wind speeds reached a peak of 90 mph with sustained winds ranging from 80-90 miles per hour and gusts up to 100 miles an hour (160 km/h). Its central pressure is not known. The following day, November 24, the eye of hurricane passed approximately 25 miles north of the northwestern coast of Kauai. However, its radius of maximum winds was right over the island, causing maximum destruction.

Iwa continued in a northeastward direction losing energy and intensity. It became a tropical storm again on November 24 and dissipated on November 25, 1982.

There was a Hawaii National Guard mobilization, but there is little documentation of the response.
