MIAMI (AP) — Rough surf was possible for Hawaii and Mexico on Tuesday thanks to two tropical cyclones in the Pacific Ocean that forecasters said were sending strong waves to some coastal areas.

Tropical Storm Fausto was expected to pass just north of the Hawaiian islands starting Tuesday night, according to the National Hurricane Center in Miami. Fausto had maximum sustained winds of 40 mph (65 kph) and was expected to weaken from tropical storm strength early Wednesday.

On Tuesday, Fausto was about 310 miles (500 kilometers) east-northeast of Honolulu and moving west-northwest near 12 mph (19 kph). Forecasters said strong currents from the tropical storm could create dangerous conditions on some Hawaii beaches.

Meanwhile, Hurricane Genevieve strengthened to a Category 4, the hurricane center said. Maximum sustained winds were 130 mph (215 kph) for the major hurricane, which was about 590 miles (950 kilometers) west-southwest of the southern tip of the Baja California peninsula.

Swells from Genevieve were reaching Baja California and coastal southwestern Mexico. Forecasters warned of life-threatening surf and rip current conditions.

On the forecast track, Genevieve was expected to fluctuate in intensity for about a day before consistently weakening.
