Tropical Depression 19E, the 19th tropical depression of the season, is expected to strengthen into a hurricane this weekend.

As Tropical Depression Nora weakens and moves on a path southeast of Hawaii, a new tropical cyclone formed in the East Pacific tonight.

Tropical Depression 19E is expected to strengthen into a tropical storm tonight and a hurricane by this weekend as it approaches the Central Pacific.

It’s too early to say if the storm, which will be named Olaf, will have an effect on Hawaii’s weather.

Remnants of Nora, however, will likely bring an increased chance of showers to the islands and slightly more humid conditions this weekend. 

The storm also generated high surf on east shores of the Big Island. A high surf advisory is posted as waves with 6- to 9-foot faces arrive through 6 p.m. Thursday.

Nora weakened to a tropical depression and by 11 p.m. tonight, it was about 325 miles southeast of Hilo with sustained winds of 30 mph. Nora was traveling northwest at 7 mph. Wind shear should weaken the storm into a remnant low on Wednesday.

Nora should slowly move in a west-northwest direction and what’s left of the storm will be blown to the southwest by easterly trade winds.

“Models show remnant tropical moisture associated with Nora getting caught up in the trade wind flow and moving across the islands as early as Thursday night for the Big Island and spreading westward through the weekend,” the National Weather Service said in a forecast advisory this evening. “Showers associated with this batch of tropical moisture will be focused over the windward sides of the islands, especially the Big Island and Maui County as Nora passes closest to these islands.”

At 11 p.m. Tropical Depression 19E was 1,070 miles southwest of Baja California, moving west at 35 mph with sustained winds of 35 mph.

If it enters the Central Pacific as a hurricane or a tropical storm, it will be the 14th named storm in the Central Pacific this season. Tropical Depression 8C formed in the Central Pacific earlier this month, but did not strengthen into a named tropical storm.
