Associate Press Release
HONOLULU (AP) -- Weather officials say Tropical Storm Flossie is weakening as it slowly moves westward across the Pacific toward Hawaii, but is still expected to bring heavy rains and winds up to 60 mph when it reaches the state late Sunday night or early Monday morning.
The National Weather Service said Sunday that Flossie could bring flash flooding, mudslides, tornadoes and waterspouts.
The service issued a tropical storm warning for Oahu, Hawaii's most populous island with the city of Honolulu, to go along with previous warnings for the Big Island, Maui, Molokai and Lanai. The warning means the storm represents a threat to life and property.
Michael Cantin, a warning coordination meteorologist with the National Weather Service in Honolulu, said Sunday that the tropical storm warnings were expanded because the storm strengthened overnight Saturday, before it began weakening Sunday.
Cantin said heavy rains are likely with winds a growing possibility, including gusts able to knock down power poles and blow away loose objects.
"These winds will be strong enough to pick up debris and throw things around," Cantin said.
The service also issued a tropical storm watch for Kauai and Niihau, a less severe notice, asking people to make a plan and pay attention to see if things get worse.
Officials warned people to cancel beach trips, finish necessary storm preparations and evacuate if asked by local officials.
Mike McCartney, chief executive of the Hawaii Tourism Authority, said Sunday afternoon that some airlines have begun to adjust flights.
"Visitors should contact their airlines and hotels to confirm their travel plans," he said.
State officials on Saturday closed trails and campgrounds on the Big Island, and warned people to avoid forest areas until Flossie clears.
"Hikers, campers or hunters should avoid trails, streams and back-country areas under these conditions," said William Aila Jr., chairman of the Department of Land and Natural Resources.
It's not immediately clear which island faces the most danger, though the Big Island - the easternmost island in the archipelago - is likely the first in Flossie's path. Flossie's center was expected to pass near the Big Island and Maui on Monday morning and then south of Oahu several hours later on Monday evening into Tuesday morning.
Cantin said Flossie could stray from its currently projected path up to 60 miles north or south as it crosses the Hawaiian islands and end up some 100 miles away from where forecasters project it to be by the time it passes.
Cantin said the storm is likely to shift south if it gets weaker and north if it gets stronger.
The storm could drop up to 15 inches of rain to windward areas of Maui and Hawaii counties, and 6 to 10 inches in other areas, forecasters said. Up to a foot of rain could fall on windward Oahu and 4 to 8 inches in central and leeward areas. Kauai may see 2 to 4 inches of rain, with up to 6 inches on windward slopes.
Waves of 12 to 18 feet are expected for the Big Island and Maui, with surf of 10 to 15 feet on other islands.
Despite the system weakening, the current forecast keeps Flossie as a tropical storm through Wednesday.
