The U.S. National Hurricane Center in Miami, Florida says Hurricane Hilary will continue to weaken in the Pacific Ocean off the coast of Baja California. The storm could be downgraded to a tropical storm by Thursday.

The Hurricane Center said Wednesday that Hilary had already weakened to a category 1 storm on the five-point scale of hurricane intensity, with winds of 150 kilometers per hour.

The storm is not expected to make landfall, and no coastal watches or warnings are in effect.

However, forecasters warn that swells generated by the hurricane are affecting portions of the southwestern coast of Mexico and the southern Baja California region. Forecasters say these swells are likely causing life-threatening surf and rip current conditions.

The U.S. Hurricane Center also is tracking two Atlantic storm systems.

A tropical depression is expected to strengthen into Tropical Storm Ophelia Wednesday. Ophelia, located east of the Leeward Islands, has top sustained winds of 55 kilometers-per-hour and is expected to turn northward as it strengthens over the next several days. Ophelia is expected to produce heavy rain across the Leeward Islands.

Far out in the eastern Atlantic, the hurricane center is monitoring Tropical Storm Philippe as it continues to weaken. Philippe has top winds of 65 kilometer-per-hour. No coastal watches or warnings have been posted and the storm is expected to be downgraded to a tropical depression late Wednesday.
