At 5 p.m., Hilda has weakened to a remnant low.

The post-tropical cyclone is located about 275 miles south of Hilo and about 400 miles south-southeast of Honolulu. The depression is moving toward the west-southwest near 14 mph, and this motion is expected to continue through system dissipation early Saturday.

Maximum sustained winds are near 30 mph with higher gusts.

Forecasts show Hilda passing far enough to the south of the Hawaiian Islands to avoid any wind impacts. However, the associated moisture plume north of the system may trigger heavy rainfall over portions of the state, especially over Hawaii Island.

Summary of 5 p.m. information:

  • Location: 15.8N 155.9W
  • About 275 miles S of Hilo
  • About 400 miles SSE of Honolulu
  • Maximum sustained winds: 30 mph
  • Present movement: WSW at 14 mph
  • Minimum central pressure: 1008 mb

Distances at 5 p.m.:

  • 275 miles SSW of Hilo
  • 275 miles S of Kailua-Kona
  • 215 miles S of South Point
  • 345 miles S of Hana
  • 355 miles S of Kahului
  • 375 miles S of Kaunakakai
  • 350 miles S of Lanai City
  • 405 miles SSE of Honolulu
  • 405 miles SSE of Joint Base Phh
  • 500 miles SSE of Barking Sands
  • 480 miles SSE of Lihue

U.S. Air Force Hurricane Hunters began flying missions into Hilda Sunday evening. They started flying at six-hour intervals Tuesday night.

Watches and warnings:

The flash flood watch continues for Hawaii Island from 6 am this morning to 6 am Saturday.

Abundant moisture from Hilda is expected to move over Hawaii Island. Storm total rainfall amounts of 4 to 8 inches with local amounts up to 12 inches are possible. Highest amounts are expected to occur along the east and southeast facing slopes.

In addition to flood prone areas, heavy rain events of this size may cause flooding in areas outside of the designated flood zones. Low spots in roads will become dangerous and impassable due to severe runoff. High amounts of debris in streams and gulches may clog bridges and culverts resulting in dangerous flooding outside the normal channels and significant property damage.
