Tropical Storm Ulika continued to weaken overnight.

At 5 a.m., Ulika’s winds decreased to 45 mph, down from 60 mph Wednesday.

Ulika is still in the East Pacific, about 1,030 miles east of Hilo. The storm is moving northwest at a slow 7 mph. But it is expected take a sharp westerly turn on Friday as it breaks up and tradewinds blow what’s left of Ulika toward Hawaii.

Tropical-storm-force winds extend outward up to 35 miles from the center.

Ulika’s remnants could bring increased humidity and an increased chance of showers over the islands starting as early as this weekend.
