Tropical Storm Eugene has formed in the East Pacific off the coast of Mexico and is expected to briefly grow into a hurricane before dissipating next week.

According to the National Hurricane Center in Miami, Eugene was about 725 miles south of the southern tip of Baja California, moving northwest at 9 mph at 5 p.m. Hawaii time. Its maximum sustained winds were 45 mph with higher gusts. Tropical storm-force winds extend up to 70 miles from the center, according to the hurricane center.

Eugene is expected to become a Category 1 hurricane Sunday with maximum sustained winds of 80 mph, but dissipate by midweek as it moves northwest over cooler waters.
