Henriette has weakened to a post-tropical remnant low, ending the forecast advisories issued by the Central Pacific Hurricane Center for the system.

At 11 a.m., Henriette was tracked passing several hundred miles south of the Hawaiian Islands.

The CPHC tracked the system at: 485 miles SSW of Hilo; 460 miles SSW of Kailua-Kona; 415 miles SSW of South Point; 530 miles SSW of Kahului; 530 miles S of Kaunakakai; 515 miles SSW of Lanai City; 540 miles S of Honolulu; 580 miles S of Lihue; and 590 miles S of Niihau.

Maximum sustained winds were 35 mph, with present movement toward the west at 22 mph, according to the CPHC forecast.

Agency officials say the remnant low will continue to weaken over the next day or two until dissipation occurs.

Forecasters are also tracking an area of low pressure located about 1,400 miles ESE of the Big Island of Hawaiʻi.

The CPHC issued an update stating that the trough continues to produce disorganized showers and thunderstorms.  Any development, forecasters say, is expected to be slow to occur during the next few days as it continues on a past westward at 10 to 15 mph.

The CPHC forecast says that this system has a low, 10% chance of becoming a tropical cyclone during the next two days.
