Tropical Storm Nora continues to weaken and will not reach hurricane strength as it begins a turn to the northwest, the Central Pacific Hurricane Center said.

At 5 p.m., Nora was about 670 miles southeast of Hilo moving west-northwest at 12 mph. It had sustained winds of 50 mph, down from 70 mph Sunday night.

Tropical storm-force winds extended outward 70 miles from the center of the storm.

The storm is expected to take a northwesterly turn today and then swing more to the north Tuesday or Wednesday. As it weakens to a post-tropical cyclone, tradewinds may push what’s left of Nora to the southwest this weekend.

Forecasters say any moisture associated with Nora should remain southeast of the islands.
