NOAA predicting Tropical Storm Ana to strengthen
Surfersvillage Global Surf News, 16 October, 2014 - Tropical Storm Ana is churning across the central Pacific with sustained winds of up to 70 miles per hour (113 kph), and is expected to strengthen into a hurricane with possible landfall in Hawaii this weekend, forecasters said.
Ana, about 680 miles (1,100 km) southeast of Hawaii's Big Island on Wednesday morning, is a comparatively weaker system, with maximum sustained winds expected to top out at about 90 mph (145 kph), just below the upper limits of a Category 1 storm, National Weather Service meteorologists said.
Tropical storms get classified as hurricanes when their maximum sustained winds reach 74 mph (119 kph), a level Ana was expected to reach by Wednesday night, forecasters said. "It's probably going to become a hurricane before the day is out," said Dennis Feltgen, a meteorologist for the National Hurricane Center in Miami.
Tropical storm-force winds extended outward by up to 65 miles (100 km) from Ana's center, with large swells from the storm expected to hit the eastern shores of Hawaii's main islands by late on Thursday, the Hurricane Center reported.
If Ana remains on a track to hit Hawaii, it could make landfall on the Big Island by late Friday night or early Saturday morning, said Matthew Foster, a meteorologist with the Central Pacific Hurricane Center in Honolulu.
