The large expansive subtropical ridge to the north of the hurricane is forecast to remain intact and gradually build westward to the north of the Hawaiian Islands throughout the 120-h forecast period.
The eye of the Category 2 storm was about 1,775 miles west-southwest of the southern tip of the Baja Peninsula and 1,505 miles east-southeast of Hilo, Hawaii, as of the NHC's 2 p.m. PDT forecast update. There has been little change in the models over the past couple of days, and the latest NHC guidance, especially the consensus track models, required no significant changes to the previous advisory track.
Lane is moving toward the west near 16 miles per hour and is forecast to cross into the Central Pacific basin tomorrow (Saturday, Aug. 18, 2018).
Residents in Hawaii have been warned to keep aware of any alerts issued in relation to Hurricane Lane, which comes just a week after Hurricane Hector glanced off Hawaii's Big Island.
The storm is expected to weaken to a Category 1 (sustained winds of 74-95 mph) by Wednesday, the National Hurricane Center says.
The agency expects the storm to strengthen into a major hurricane - Category 3 or higher - later Friday.
The NHC intensity forecast suggests Lane's winds could increase to 125mph on Saturday.
Hurricane Hector caused similar conditions when it passed by Big Island on August 8.
After that, some fluctuations in intensity are expected tonight and Sunday.
"By midday Saturday, it should be approximately 1,000 miles southeast of the Big Island".
