At 5 a.m., the tropical storm warning was discontinued for Hawaii Island. A tropical storm warning is still in effect for Oahu, Maui, Lanai, Molokai, and Kahoolawe, and a tropical storm watch is in effect for Kauai and Niihau.

The National Weather Service says the center of Tropical Storm Lane was located about 110 miles south-southwest of Honolulu. Lane is slowly moving north near 3 mph.

The storm is expected to continue crawling in this direction through Saturday morning, and then pick up speed as it turns toward the west later in the day into Sunday. 

On the forecast track, the center of Lane will pass south of Kauai and Niihau later on Saturday and through the night. 

Maximum sustained winds have continues to weaken and are near 60 mph with higher gusts. The forecast has Lane continuing to weaken over the next few days.

Tropical-storm-force winds extend outward up to 125 miles from the center.

HAZARDS AFFECTING LAND

Maui: Tropical storm conditions are still expected in and near outer rain bands that will affect Oahu and Maui County today. Tropical storm conditions are possible on Kauai starting later today.

RAINFALL: Lane’s outer rain bands will produce excessive rainfall this weekend, which could lead to additional flash flooding and landslides. Lane is expected to produce additional rain accumulations of 5 to 10 inches in some areas. Localized storm total amounts well in excess of 40 inches have already been observed along the windward side of the Big Island.

SURF: Large swells generated by Lane will impact the Hawaiian Islands. These swells will produce high surf along exposed south and east shorelines today.

During the past few hours, satellite imagery shows a burst of convection has developed near the circulation center of Lane, which was nearly totally exposed Friday evening. Lightning has also been persistent near the core of this deep convection. More importantly, we have been able to see the apparent center of circulation in the radar reflectivity data, which helps our confidence in the latest location and motion. Lane continues to weaken, so taking a blend of the latest satellite intensity estimates, we have lowered the initial intensity to 50 knots.

The latest motion for this advisory is 350/3 knots. The current track forecast has been nudged slightly to the right through 36 hours, with little change from days 2 through 5. This forecast closely follows the HWRF, and is to the right of the consensus models such as TVCN, GFEX and HCCA. There are only subtle changes in the track forecast compared with the previous from days 2 through 5. Lane is expected to continue weakening due to vertical wind shear of greater than 30 knots. The latest intensity forecast has Lane becoming post-tropical by day 4. Assuming this low survives, it may eventually become an extratropical gale low in the vicinity of the Northwestern Hawaiian Islands by day 5.

KEY MESSAGES:

1.  Effects from tropical storms can and do extend well from the center. Rain bands around the northern and eastern periphery of Lane are still bringing persistent flooding rainfall across parts of the state. In addition, strong winds are also possible in these rain bands. Winds will be accelerated over higher terrain, through gaps, and where winds blow downslope. Winds will also be stronger at the upper floors of high rise buildings.
