The Wind Advisory has been canceled by the National Weather Service. The High Surf Advisory remains posted for east facing shores with 5 to 8 foot faces expected.

Niala rainfall is not likely to make it as far north as Maui County. However, a band of moisture, remnants of a front, will focus showers across windward slopes, though leeward areas will experience periods of rainfall as well.

***Updated with information from the Central Pacific Hurricane Center’s 5 a.m. bulletin.***

Niala is expected to continue to weaken as it passes south of the state during the next couple of days. The system is currently moving west-southwest near 7 mph and has maximum sustained winds of 50 mph.

Locally windy conditions will persist over Maui County into Monday as strong high pressure remains north of the state, and a Wind Advisory is in effect. Winds of 20 to 30 mph are expected with gusts as high as 50 mph where the terrain accelerates those winds.

We expect a “wet trade wind weather pattern” today with scattered showers favoring windward spots and isolated heavy rain possible. Leeward areas are expected to be partly cloudy with isolated showers.

A High Surf Advisory is also in effect. Large surf will continue to affect the east and southeast shores of Maui County through tomorrow with 6 to 9 foot faces expected today and 5 to 8 foot waves forecast for tomorrow.

Niala’s track has been adjusted only slightly with the general motion continuing in a west-southwest direction.

Niala’s track remains relatively unchanged since the last update. Maximum sustained winds are near 65 mph making it a solid tropical storm.

The system is projected to move west through Sunday, before taking a southwest turn on Monday. Niala is moving west at 8 mph and expected to pass 120 to 150 miles south of the Big Island Sunday afternoon should it remain on its current track.

The system is being affected by west-southwesterly shear and expected to begin a weakening trend.

Information in the video below remains pertinent to our current situation. Even so, the projected rainfall numbers have dropped a tad to 2-8 inches of rain expected in Hawaii County with up to a foot of rain expected in some spots on the Big Island.

Meteorologist Malika Dudley put together this video update which includes important safety information from the forecasters at the Central Pacific Hurricane Center and National Weather Service in Honolulu.

As of the 2 p.m. CPHC update the strong high pressure center far north of Hawaii appears to be gaining influence on Niala with the tight pressure gradient between this and Niala producing windy conditions across Maui County through Sunday night.

Isolated showers, sometimes heavy, are forecast to pass through Maui County.  Heaviest rains will most likely occur later tonight and into Sunday along the north and east as enhanced moisture from Niala passes through.

Tropical Storm Niala strengthened over night as it nears the Big Island.

As of 5 a.m., the Central Pacific Hurricane Center reported that Tropical Storm Niala was about 280 miles southeast of Hilo, holding maximum sustained winds of 60 miles per hour, and was moving in a northwest direction at seven mph.

Tropical Storm Niala is still expected to make a turn towards the west this weekend. Forward speed is also expected to decrease.

CPHC forecasters say Tropical Storm Niala should pass about 150 miles south of the Big Island Sunday night.

Rain is expected to reach totals of six to 12 inches, with the possibility of up to 16 inches in some areas. The large amount of rain expected could cause life-threatening flash floods, rockslides, and mudslides.

Tropical Storm Niala will produce large surf along southeast shores over the weekend and into next week.
