Tropical Storm Henriette strengthened into a category one hurricane in the Pacific Ocean on Tuesday but is moving away from the coast of Mexico, officials said.

"Henriette has continued to strengthen overnight and early this morning," the US National Hurricane Center said.

In the early hours of Tuesday the storm was 1,513 miles (2,435 kilometers) southwest of Cabo San Lucas in Mexico's Baja California Sur state.

"Because of its remoteness there is no alert" but it will "intensify over the next 48 hours off the coast of Mexico," the country's National Water Commission said.

The storm is moving northwest at a speed of 11 miles per hour, with sustained winds of 75 miles per hour.

The last hurricane to hit Mexico's Pacific coast was Erick in July, which left two people dead and five hundred victims in its wake.

Meteorologists from the National Oceanic and Atmospheric Administration warned in May that this year's hurricane season would be more active than usual.

They predicted the formation of 13 to 20 named tropical storms and six to 11 hurricanes -- including three to six major ones, with winds stronger than 110 miles per hour.

The hurricane season lasts from June 1 to November 30.
