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.
