Ana Moving Away From Main Hawaiian Islands
Oct 22, 2014 3:54 PM
The Eastern Pacific Basin remains quiet, and no tropical development is expected for the next several days.
In the central Pacific Basin, Ana is slowly moving to the northwest away from Hawaii. The storm remains disorganized as wind shear is displacing the thunderstorm activity from the center of circulation.
The storm will make more of a turn to the north tonight, then to the northeast and begin to accelerate later Thursday and through the weekend. Ana is expected to strengthen some Thursday and Friday, but it will remain below hurricane strength.
Ana will continue to bring occasional wind and rain to the mostly uninhabited northwestern Hawaiian Islands through this evening.

The Saffir-Simpson Wind Scale is a categorical classification of hurricanes based on their wind speed, used by the U.S. government's National Hurricane Center.
To qualify as a Category 5 hurricane on the Saffir-Simpson hurricane intensity scale, maximum sustained winds must exceed 155 mph (135 kt).
Hurricanes that have a severe impact on lives or the economy are remembered by generations after the devastation they caused, and some go into weather history.
AccuWeather.com has created a number of specialty maps designed for tracking the progress of tropical storms and hurricanes. Use these maps in conjunction with our Hurricane Position graphic, as well as statements issued by the NHC with storm positions.
Hurricanes (by whatever name) are by far most common in the Pacific Ocean, with the western Pacific being most active. In some years, the Philippines are struck by more than 20 tropical storms and typhoons.
