A Hawaii tsunami warning that spurred coastal evacuations statewide was downgraded to a tsunami advisory early Sunday, ending the threat of serious damage less than three hours after the first waves hit the islands. Hawaii Gov. Neil Abercrombie said early Sunday that the Aloha State was lucky to avoid more severe surges after a powerful earthquake struck off the coast of Canada. Abercrombie said beaches and harbors are still closed statewide. "We're very, very grateful that we can go home tonight counting our blessings," Abercrombie said. Meanwhile, the National Weather Service canceled tsunami advisories for Canada and Oregon, leaving northern California as the only spot in North America still under a tsunami advisory. The first waves hitting Hawaii on Saturday night were smaller than expected. Gerard Fryer, a geologist tracking the tsunami for the Pacific Tsunami Warning Center, said the largest wave in the first 45 minutes of the tsunami was measured in Maui at more than 5 feet, about 2 feet higher than normal sea levels. No major damage was reported. Read more: http://www.huffingtonpost.com/2012/10/28/hawaii-tsunami-2012_n_2033457.html
