Ana no longer a post-tropical cyclone

Former Hurricane Ana, whose damaging winds avoided Oahu by only about 50 miles, is no more.

Thirteen days after it formed, Ana is merging with a larger storm and will no longer be even a post-tropical cyclone.

The Central Pacific Hurricane Center issued its last advisory on Ana Sunday morning.

The storm still had 60 mph winds as it moved east, 1,555 miles north-northeast of Hawaii.

But strong windshear and colder air in the North Pacific have weakened Ana.

What’s left of Ana, now part of a larger storm, will move ashore in British Columbia on Tuesday, likely bringing rains and winds to the region.

During its 13-day life, Ana took a C-shaped path, moving close enough to the islands last weekend to bring storm surf, heavy rains and activate emergency preparations, before moving off to the northwest and then north of the main Hawaiian islands.

High pressure protected Hawaii, as a system that normally sends tradewinds to the state moved over the islands and Ana steered a course around the edges of the high pressure system.

The storm still dumped more than 24 hours of rain on Oahu, with Manoa getting nearly a foot of water.

At its peak Ana had sustained winds of 80 mph and was 200 miles wide.

Stormwater runoff overwhelmed the Sand Island Sewage Treatment Plant.

After 5,000 gallons of raw sewage poured out of manholes into Hono-lulu Harbor on Sunday morning, sewage treatment plant workers discovered a series of below-ground rooms, tunnels and critical panels under 6 to 8 feet of effluent and water that reached as high as door sills.

"Before Ana left she left us a good kick in the butt," Honolulu Mayor Kirk Caldwell said. "The good news is there were no injuries to anyone."
