KAILUA-KONA, Hawaii (AP) — Hurricane Ana was carving a path just south of Hawaii, sending waves pounding some shorelines, heavy rain prompting a flood advisory, and winds strong enough for officials to urge caution. The center of the powerful Pacific storm was expected to remain 150 miles away from the Big Island as it passed late Friday night. Forecasters late Friday said there was little chance for hurricane conditions on the islands, but a tropical storm watch remained in effect throughout the archipelago and winds were expected to reach nearly 40 mph. "Any of the islands could experience tropical storm impacts...so it's important to still prepare and make plans," said Chris Brenchley, a weather service meteorologist. Waves were expected to crest to 10 to 15 feet on both the North and South shores of Hawaii's islands late Saturday and to remain tall through Sunday. Late Friday, the National Weather Service issued a flood advisory for parts of the Big Island until shortly after midnight, saying rain was falling in some areas at a rate of 2- to- 3-inches an hour. The NWS said Friday that Ana became a Category 1 hurricane about 230 miles south of Hilo with maximum sustained winds of 80 mph.Read more on NewsOK.com
