Flossie May Leave Showers in Her Wake

July 30, 2013

Even as Flossie drifts away and dissipates to a remnant of a tropical storm, she leaves behind ample moisture to cause thunderstorms this afternoon and heavy rain Wednesday in Honolulu, forecasters said.

Tropical moisture in the air will create hot and humid conditions today and Wednesday that can help form rain clouds over central and leeward areas of all islands. The forecast for Honolulu calls for the chance of thunder storms this afternoon and the possibility of heavy rain Wednesday until cooling trade winds blow away the muggy conditions on Thursday.

At 2 a.m., the center of Tropical Depression Flossie was about 50 miles north of Lihue, heading west-northwest at 18 mph. It was expected to weaken into a remnant low in the next day and a half.

As Flossie moved away from the state and weakened, the National Weather Service dropped a flood advisory for Oahu that had been posted until 2:15 a.m., when rains from the storm moved onshore from the south after 11:30 p.m. over parts of the island.

A flash flood watch remains in effect for the entire state through late Tuesday night.

A high surf advisory for Hawaii island, a high surf warning for Kauai, Oahu, Maui and Molokai, small craft advisories for Hawaiian waters and a wind advisory for the Haleakala summit are expected to expire later this morning.

The Hawaii Red Cross was preparing to close its storm shelters this morning. The Red Cross sheltered 45 people on Maui in four locations and 132 people on Oahu in seven locations.

Flossie dropped most of its rain over Maui, where lightning storms knocked out power to thousands. Maui Electric crews worked through the night to restore power to about 4,500 customers who were still without electricity at 9:45 p.m. in parts of Wailuku, and Waiehu to Kahakuloa. Small pockets of customers in Kahului, Haiku and Kula are also affected,

About 900 customers in Hana were without power overnight, when the storm damaged power lines.

Lightning on Maui sent a Haiku man to the hospital in stable condition when he was struck by a bolt. A home owner in Kahului will be looking to repair a 10-inch hole in his roof and a five-inch hole in the 2-story home's gable after lightning struck the house at 40 Kipapa Place. A resident was home at the time of the lightning strike, but was uninjured.

The lightning storm appeared to be heading to Oahu at about 8:30 p.m., but radar showed it died out before reaching shore.

Flossie approached the islands as a strong tropical storm with maximum sustained winds of 70 mph over the weekend, but quickly broke apart Monday as wind shea and dry air zapped Flossie of its power as it approached the Big Island and Maui.

Forecasters had feared up to 15 inches of rain in isolated windward areas, but Flossie, which brough rains of 3 to 4 inches an hour, moved quickly over the islands and didn't stay too long over any one place.

The Kaupo Gap in East Maui got the most rain in the state with 5.3 inches falling in the 24-hour period ending at 2 a.m. Puu Kukui in the West Maui Mountains got 4.3 inches and Ulupalakua recorded 3.6 inches.

Puu Alii in the northeast side of Molokai got nearly 3.8 inches.

Kawainui Stream near Kamuela on the Big Island received 2.5 inches, 1.5 inches was recored in Honokaa, and 2.2 inches fell at Kahua Ranch in North Kohala.

On Oahu, 2.6 inches fell on the Oahu Forest National Wildlife Reserve in the northern Koolau mountains, Upper Nuuanu got 1.3 inches and the Lyon Aboretum in Manoa saw 1.2 inches of rain.

The Kilohana rain gage on Kauai recorded 3.9 inches, while 3 inches fell on Mt. Waialeale and a little less than 1.2 inches fell in Wainiha.
