HONOLULU (AP) — A Pacific tempest packing hurricane force winds brushed Hawaii over the weekend with heavy rain, high surf and strong winds, but the islands rode out the storm with no reports of any serious problems. Hurricane Ana was downgraded to a tropical storm late Sunday afternoon as it began to pull away from the state's more populated islands. A tropical storm watch was canceled Sunday for Oahu, the state's most populous island. [...] a flash flood warning remained in effect until 8 p.m.
