Pacific Tropics Active as El Niño Fuels Two Tropical Storms

The Pacific hurricane season is showing no signs of slowing down as multiple tropical systems churn across the basin, with warm ocean temperatures and a strengthening El Niño helping create favorable conditions for development.

Tropical Storms Karina and Lowell are among the latest systems to form over the open Pacific. Both storms are forecast to strengthen as they remain over warm water and could reach hurricane intensity this weekend.Karina is moving northwest across the Eastern Pacific and is expected to continue strengthening while remaining over the open ocean. The storm is not currently expected to pose a direct threat to land.

Farther west, Lowell is also forecast to intensify. The system is expected to make several changes in direction before eventually tracking westward this weekend. Lowell could become a hurricane by Saturday night

While Lowell remains far southeast of Hawaii, its longer-range track will be monitored closely. Some forecast guidance suggests the system could eventually move into the Central Pacific, potentially bringing indirect impacts to Hawaii. However, there remains considerable uncertainty in the forecast at that range.

The active pattern may not end with the current systems. There is also another area southwest of Mexico where an area of low pressure could develop this weekend. Atmospheric and oceanic conditions are expected to become favorable for additional organization, giving the disturbance a high chance of tropical development over the next several days.

Another disturbance south of Hawaii is also being watched, although its chances of development are currently much lower.

El Niño Helping Fuel Pacific Activity

The surge in tropical activity comes as El Niño continues to strengthen across the equatorial Pacific.

El Niño is characterized by warmer-than-average ocean temperatures across portions of the central and eastern equatorial Pacific. Those unusually warm waters can influence weather patterns around the globe while also creating an environment that can favor tropical cyclone activity in the Pacific.

This year’s El Niño has already strengthened considerably, and forecasts indicate it could become exceptionally strong later this year.

While the Pacific remains crowded with tropical systems, many of the current storms are expected to remain over open water. Still, with several additional areas being monitored, the active stretch of the 2026 Pacific hurricane season is far from over.
