Situation overview

Hurricane Lane remains a major category 3 storm late this afternoon, with maximum sustained winds of 120 mph. As of 5 PM HST, Hurricane Lane was located around 175 miles southwest of Kailua-Kona, Hawaii and 240 miles south of Honolulu, Hawaii. Lane is moving toward the north-northwest at around 6 mph. A slow general northward motion is expected to continue through Friday. A turn toward the west is expected Saturday and Sunday, with an increase in forward speed. On the forecast track, the center of Lane will move over, or dangerously close to portions of the main Hawaiian islands tonight and Friday. Regardless of the exact track, life threatening impacts are likely over many areas as this strong hurricane makes its closest approach. Do not focus on the exact forecast track or intensity of Lane. Be prepared for changes in future forecasts. Although the official forecast does not explicitly indicate Lane’s center making landfall over any of the islands, this could still occur.

The onset of damaging tropical storm-force winds is expected across portions of the Big Island tonight. In Maui County, damaging tropical storm-force winds are expected later tonight, with dangerous hurricane force winds expected in some areas Friday. On Oahu, damaging tropical storm force winds are expected to develop late tonight, with dangerous hurricane force winds expected Friday into Friday night. Tropical storm or hurricane conditions are possible on Kauai on Saturday.

Outer rain bands associated with Hurricane Lane are already affecting all the main Hawaiian Islands. Widespread heavy rainfall and flash flooding is ongoing over portions of the Big Island. The rain bands will continue to spread northwest through Friday night. Excessive rainfall is likely which could result in life threatening flash flooding, as well as landslides and mudslides. Flooding will be possible in areas that are typically not prone to flooding. Storm total rainfall amounts of 10 to 20 inches are expected to be common across the island chain, with localized amounts in excess of 30 inches.

Swells generated by Lane will produce very large life-threatening surf and dangerous rip currents along southeast, south and southwest facing shores of all of the Hawaiian islands. Large surf is likely occurring along southeast facing shores on the Big Island. Surf is expected to increase tonight along southwest facing shores of the Big Island as well as along south and southeast facing shores from Maui County to Kauai County, with the surf becoming extremely large later tonight through Saturday. Surf heights as large as 10 to 15 feet are expected in the Puna and Kau districts as well as along the Kona coast of the Big Island. Surf heights of 10 to 20 feet are expected along south and southeast facing coasts from Kauai County to Maui County.

The combination of storm surge and large breaking waves is expected to raise water levels well above normal tide levels as Hurricane Lane makes its closest approach. Water levels could reach 2 to 4 feet above normal along southeast, south and southwest facing shores from Kauai to Maui, as well as southeast, south, southwest and west facing shores of the Big Island, should Lane makes landfall. This is expected to result in significant beach erosion and overwash onto vulnerable coastal roadways tonight through Saturday as Lane makes its closest approach, particularly for vulnerable low-lying coastal areas during and around the time of the normal high tide cycles.

Tornadoes and large waterspouts will be possible with Lane, mainly along and to the right of the track of the hurricane.
