Tropical Storm Genevieve, Super Typhoon Dolphin spin in Pacific
Tropical Storm Genevieve spins in Pacific as Dolphin reaches super typhoon status near Wake Island.
AccuWeather’s Jon Porter monitors the equatorial Pacific where El Niño conditions are leading to rising sea surface temperatures. This will lead to more tropical activity in the Pacific region.
The eastern and central Pacific have become very active, with Hurricane Genevieve becoming the season's first Category 5 while churning off the coast of Mexico. Meanwhile, Dolphin, north of the Marshall Islands, near Wake Island, has reached Super Typhoon status.
A busy Pacific hurricane season was expected due to the development and strengthening of El Niño. This warm plume of water creates ideal conditions for tropical storms and hurricanes to form and strengthen in the Pacific.
A tropical depression formed on the morning of July 24, well off the coast of Mexico, and became Tropical Storm Genevieve several hours later. A day later, on Saturday, Genevieve became a hurricane. Twenty-four hours later, on Sunday, Genevieve intensified rapidly and became a powerful Category 4 hurricane with maximum sustained winds of 155 mph. During the overnight hours on Sunday, Genevieve's maximum winds reached 160 mph -- a Category 5 hurricane.

As of Thursday evening, Genevieve was a 70-mph, tropical storm. The tropical storm will track northwest through the end of the week.
Genevieve will continue to lose wind intensity this week. Massive swells generated by the powerful storm will extend outward from the center and reach the west coast of Mexico and California as sets of large waves that could pose dangers to small craft and swimmers.
Dolphin becomes a super typhoon
More than 2,000 miles southwest of Hawaii, just north of the Marshall Islands, Super Typhoon Dolphin formed in the middle of the Pacific earlier this week.

Super Typhoon Dolphin intensified rapidly from Monday to Tuesday before intensifying even further later Wednesday into Wednesday night. Super Typhoon Dolphin currently has maximum sustained winds of 155 mph. Dolphin will slowly lose wind intensity into early next week. As massive swells radiate outward from the storm's center, heavy, dangerous surf will reach many islands in the region.
Both Dolphin and Genevieve are very dangerous storms for cross-Pacific shipping.
Numerous tropical storms and hurricanes are forecast for the eastern and central Pacific basins in 2026, due to the impacts of El Niño.
