Tropical Storm Lane is forecast to make a turn toward the west and pass south of Kauai late Saturday and Saturday night. Heavy precipitation associated with Lane will continue to fall over the coastal waters, through the weekend.

Surf will remain elevated along exposed shores through Saturday as Lane begins to move off to the west. Heights along the south shores will likely lower into average range no later than Sunday. East shores will remain elevated beyond Saturday due to expected strong onshore winds filling in as Lane exits.

Weather Outlook for Saturday, 25th August 2018

Summary

Tropical Storm Lane is moving toward the north-northwest near 3 mph, and this general motion is expected to continue through Saturday morning. This will likely be followed by a turn toward the west with an increase in forward speed starting Saturday afternoon. Although Lane will continue to weaken along this track, the threat for flash flooding remains in the forecast through the weekend. The wet pattern will likely hold through the first half of next week across the western end of the state. A drying trend will gradually fill in from east to west through midweek.

Detailed Discussion

The 11 pm HST advisory from the Central Pacific Hurricane Center (CPHC) has Tropical Storm Lane positioned around 135 miles south- southwest of Honolulu tracking toward the north-northwest around 3 mph. Maximum sustained winds associated with Lane remain at 65 mph near the center. Lane is forecast to gradually make a turn toward the west Saturday afternoon, passing south of Kauai.

Although Lane will continue to weaken along the forecast track, the threat for flash flooding will continue over the weekend. The latest radar imagery showed the heaviest rainfall continuing to focus over Maui County and the Big Island this morning. No changes are anticipated through daybreak (1-3 inch per hour rates in the heaviest activity). Later today through Sunday, the rainfall and flash flooding threat will slowly shift westward toward Oahu and Kauai. As a result, the flash flood warning will likely be extended through Saturday night in later forecasts this morning.

For the extended period (next week), a trailing deep tropical moisture axis is forecast to hold over the western end of the state through the first half of the week as Lane turns northward well west of Kauai. This will keep the threat for heavy rainfall and flooding in place, mainly for Kauai and Oahu. A gradual drying trend is anticipated from east to west through midweek.
