Hurricane Ana was the second tropical cyclone in 2014 to threaten the U.S. state of Hawaii, after Iselle in August. The twenty-first named storm and fifteenth hurricane of the 2014 Pacific hurricane season, Ana formed from a disturbance that formed in the Central Pacific in mid-October. It rapidly consolidated, and a tropical depression developed by October 13. Aided by favorable conditions, Ana gradually strengthened while moving westward, threatening to pass over the island chain of Hawaii once or several times as indicated by early forecasts. By October 17, it had strengthened to a hurricane south of Hawaii and reached its peak intensity shortly afterwards while also making its closest approach. Afterwards, Ana weakened and began to fluctuate in intensity as it turned to the north and eventually northeast as it rounded a subtropical ridge and interacted with a cold front before becoming a hurricane briefly again on October 25. Ana transitioned into an extratropical cyclone on October 26, and raced across the northwest Pacific before dissipating by October 28 after it came ashore in Western Canada.
Because Ana was originally forecasted to strike the Big Island of Hawaii early in its life, tropical storm watches and eventually warnings were issued in advance of the storm.[1] These were later expanded across nearly the whole island chain as Ana nudged more to the west than forecasted. At its closest approach, Ana dropped heavy rain of nearly up to 11 inches (28 cm), although the heaviest rain missed Hawaii by nearly 20 miles (32 km), averting a potentially dangerous flooding scenario. The swath of tropical storm force winds missed the islands as well, minimizing damage by a great deal.[1]
