Three hurricanes are still churning in the Pacific, and a fourth may be on the way

Three hurricanes are still churning in the Pacific Ocean at the same time — Karina, Lowell and Marie — three days after they made this the first triple-hurricane stretch in a decade. A fourth system offshore southwestern Mexico could soon join them.

It's the first time since 2015 that three simultaneous hurricanes of any strength formed, when Kilo, Ignacio and Jimena all became major Category 4 hurricanes.

This year's El Niño conditions have contributed to hurricane formation in the Pacific and are predicted to soon become the strongest on record.

El Niño affects hurricane severity in both the Atlantic and the Pacific, leading to fewer hurricanes in the Atlantic (particularly the Caribbean) and more in the Pacific due to increased rising air over the tropical Pacific and sinking air over the tropical Atlantic.

Here's the location, path and status of each of the hurricanes:

Hurricane Karina has weakened to a Category 1 storm and is expected to dissipate by early next week without threatening land.

Karina was located about 800 miles east of Hilo, Hawaii.

It had maximum sustained winds of 75 mph.

"Karina is forecast to quickly weaken through early next week," the NHC said.

There are currently no hazards affecting land.

Hurricane Lowell is a powerful Category 4 storm expected to remain a major hurricane through the weekend. NHC forecasters said tropical storm watches will likely be required for parts of the western main Hawaiian Islands and the Papahanaumokuakea Marine National Monument later Saturday. The storm's forecast track has it moving over portions of the monument Monday night.

Lowell was located about 630 miles southwest of Lihue, Hawaii.

It had maximum sustained winds of 150 mph.

"Some fluctuations in intensity are expected during the next few days," according to the NHC. "However, Lowell is expected to remain a major hurricane for the next several days."

Swells generated by Lowell are spreading north and are expected to affect parts of the Hawaiian Islands over the next several days. They're likely to cause life-threatening surf and rip-current conditions.

Hurricane Marie is a Category 1 storm and is expected to weaken during the next few days.

Marie was located about 675 miles west of the southern tip of Baja California.

It had maximum sustained winds of 90 mph.

"Marie is expected to weaken during the next few days," the NHC said.

The NHC is monitoring a fourth area for potential development well offshore of southwestern Mexico. Forecasters give it a 60% chance of developing into a tropical depression by later this week as it moves west-northwest at 10-15 mph. If it forms and gets named, the next name on the East Pacific list is Norbert.
