Hilda has quickly intensified into a Category 2 hurricane. Maximum sustained winds are now at 105 mph with higher gusts. Additional strengthening is forecasted over the next 12 to 24 hours with a weakening trend to start on Sunday.

The storm, located 1120 miles ESE of Hilo, 1185 miles ESE of Kailua-Kona and 1145 miles ESE of South Point, continues to move W at 15 mph. A gradual turn to the west-northwest is expected over the next 48 hours.

Hilda is still quite compact and small. Hurricane force winds extend just 15 miles from the center and tropical storm force winds extend outward up to 70 miles.

FORECAST SUMMARY – High pressure to the north of the islands will keep locally breezy trades blowing through the weekend, with trades slowly diminishing early next week. A few showers can be expected to ride in on the trades from time to time, affecting mainly windward and mauka areas during the nights and mornings. It is still too soon to say if hurricane Hilda, located far to the southeast of Hawaii, will have any effect on our weather toward the middle of next week.

The storm, located 1325 miles ESE of Kahului, 1370 miles ESE of Kaunakakai and 1345 miles ESE of Lanai City. The system continues to move W at 15 mph. This motion should continue through this afternoon before the system veers west-northwest later today or tomorrow.

FORECAST SUMMARY – The center of weakening post-tropical low Guillermo is moving west-northwest near 16 mph. A moist and unstable air mass will linger over the islands today, fueling locally heavy downpours, and bringing a slight chance of thunderstorms.

Trade winds will strengthen tonight and remain locally gusty through the weekend, delivering brief windward showers that favor nights and mornings. Trade wind speeds will ease early next week, with tropical cyclone Hilda potentially nearing the islands by the middle of next week. What effects, if any, Hilda will have on our weather are entirely dependent on the track the system takes as it nears the islands.

As of 5:00 a.m. this morning, the Central Pacific Hurricane Center has issued it’s last advisory for Guillermo. The system has winds at 35 mph and is moving rapidly west-northwest at 17 mph and away. Gradual weakening is expected through dissipation on Saturday. Guillermo is currently located 325 miles NW of Hilo, 280 miles NW of Kailua-Kona and 335 miles NW of South Point.

Meanwhile, Hilda is still spinning in the Eastern Pacific at tropical storm strength. The compact system maintained maximum sustained winds of 60 mph overnight but became a little bit bigger with tropical storm force winds now extending 70 miles from the center.

Hilda is currently located 1300 miles ESE of Hilo, 1370 miles ESE of Kailua-Kona
and 1335 miles ESE of South Point. The system is moving W at 13 mph. This general motion should continue through today with a gradual turn to the WNW tonight or Saturday. The eventual forecast track has the system veering NW – just how much will depend on many factors moving forward. We will continue to watch this and bring you the latest.  Hilda is expected to reach hurricane status this evening or tomorrow as well.
