Hurricane Iselle - August 2014
August 8, 2014 - Tropical Storm Iselle, recently downgraded from hurricane status, made a rare landfall on the Big Island of Hawaii.

The center of the storm came on shore about 5 miles east of Pahala, on the islands southern shore, at 2:30 AM HST, with maximum sustained winds around 60 mph.
