Interests elsewhere in the main Hawaiian Islands, and across the Northwestern Hawaiian Islands, should continue to closely monitor the progress of Hurricane Lane. Additional Tropical Storm or Hurricane Watches will likely be issued this afternoon or tonight. For storm information specific to your area, please monitor products issued by the National Weather Service office in Honolulu Hawaii. DISCUSSION AND OUTLOOK ---------------------- At 1100 AM HST (2100 UTC), the center of Hurricane Lane was located by U.S. Air Force Reserve Hurricane Hunter aircraft near latitude 14.3 North, longitude 153.2 West. Lane is moving toward the west-northwest near 9 mph (15 km/h) and this motion is expected to continue through tonight. A turn toward the northwest is expected Wednesday into Thursday. On the forecast track, the center of Lane will move very close to or over the main Hawaiian Islands from Thursday through Saturday. Maximum sustained winds are near 155 mph (250 km/h) with higher gusts. Lane is a powerful Category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Slow weakening is forecast during the next 48 hours, but Lane is forecast to remain a dangerous hurricane as it draws closer to the Hawaiian Islands. Hurricane-force winds extend outward up to 40 miles (65 km) from the center and tropical-storm-force winds extend outward up to 140 miles (220 km). The minimum central pressure as recently reported by hurricane hunter aircraft is 941 mb (27.79 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are possible within the Hurricane Watch area beginning Wednesday night, with hurricane conditions possible on Thursday. RAINFALL: Excessive rainfall associated with Lane is expected to affect portions of the Hawaiian Islands from Wednesday into the weekend, leading to flash flooding and landslides. Lane is expected to produce total rain accumulations of 10 to 15 inches with isolated maximum amounts of 20 inches over the Hawaiian Islands. SURF: Large swells generated by Lane will impact the Hawaiian Islands, beginning tonight on the Big Island and spreading across the remainder of the island chain Wednesday through Thursday. These swells will produce large and potentially damaging surf along exposed west, south and east facing shorelines. NEXT ADVISORY ------------- Next intermediate advisory at 200 PM HST.
