SUMMARY OF 200 AM HST.1200 UTC.INFORMATIONĪBOUT 560 MI.900 KM ESE OF HONOLULU HAWAII ISELLE TAKING AIM AT THE BIG ISLAND OF HAWAII. NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI EP092014 HURRICANE ISELLE INTERMEDIATE ADVISORY NUMBER 29A Here are the latest stats and discussion on Iselle, which will slam the Big Island and cause damage tonight. Dot brought sustained winds of 81 mph with gusts to 103 mph to Kilauea Light. August 1959: Hurricane Dot entered the Central Pacific as a Category 4 hurricane just south of Hawaii, but weakened to a Category 1 storm before making landfall on Kauai. All the islands reported some surf damage along their southwest facing shores, and wind damage was widespread on Kauai. Iwa killed one person and did $250 million in damage, making it the second most damaging hurricane to ever hit Hawaii. Although it was only a Category 1 storm, it passed just miles west of Kauai, moving at a speed of nearly 50 miles per hour (80 km/h). November 1982: Hurricane Iwa was one of Hawaii's most damaging hurricanes. It hit the island of Kauai as a Category 4 on September 11, killing six and causing $2 billion in damage. A brief summary of the three most significant hurricanes to affect Hawaii in modern times: September 1992: Hurricane Iniki was the strongest, deadliest, and most damaging hurricane to affect Hawaii since records began. Only one tropical storm has hit the islands since 1949-an unnamed 1958 storm that hit the Big Island. Since 1949, the Hawaiian Islands have received a direct hit from just two hurricanes-Dot in 1959, and Iniki in 1992. Tropical storms and hurricanes are rare in the Hawaiian Islands. August is the peak month, followed by July, then September. This number has ranged from zero, most recently as 1979, to as many as eleven in 19. On average, between four and five tropical cyclones are observed in the Central Pacific every year.
Iselle may be the first hurricane on record to make landfall on the Big Island, according to Weather Underground's hurricane specialist Dr. Hurricane Iselle has maintained a good deal of strength and 85 miles per hour sustained winds as it churns toward the Big Island of Hawaii tonight.
