Tropical Cyclone Developments on September 2, 2025

Major Takeaway: The National Hurricane Center reported significant tropical activity on September 2, 2025, as Hurricane Kiko intensified in the eastern Pacific, Tropical Depression Twelve-E strengthened into Tropical Storm Lorena off Mexico’s coast, and an Atlantic tropical wave gained a 70 percent chance of becoming Tropical Storm Gabrielle.

Hurricane Kiko Strengthens in Eastern Pacific

Hurricane Kiko formed over the eastern Pacific Ocean on Tuesday, packing maximum sustained winds of 75 mph (120 km/h) and moving westward at 7 mph (11 km/h). Forecasters expect Kiko to undergo steady intensification over the next few days, potentially reaching Category 2 strength by Thursday, before encountering cooler waters that should curb further strengthening.

There are no coastal watches or warnings in effect for Kiko, and the system poses no immediate threats to land. Satellite imagery shows a growing central dense overcast and an increasingly defined eye as the hurricane traverses warm sea surface temperatures well southeast of Hawaii.

Tropical Depression Twelve-E Becomes Tropical Storm Lorena

A second system in the Pacific, Tropical Depression Twelve-E, emerged roughly 190 miles south of Manzanillo, Mexico, with 35 mph winds on Monday. By Tuesday morning, it had intensified into Tropical Storm Lorena, with forecast models projecting hurricane status by Wednesday before landfall on the Baja California peninsula this weekend.

• A Tropical Storm Watch may be issued later Tuesday for parts of Baja California Sur as conditions conducive to tropical-storm-force winds develop within 48 hours.
• Rainfall totals of 4-8 inches are expected across western and northwestern Mexico, with isolated areas possibly receiving higher amounts, raising flash-flood concerns in mountainous terrain.

Atlantic Tropical Wave Poised to Become Gabrielle

In the Atlantic basin, a tropical wave located south of the Cabo Verde Islands showed increasing organization, prompting the NHC to assign a 70 percent probability of development into a tropical depression or storm by week’s end. If it attains tropical-storm strength, it will be named Gabrielle-the seventh named storm of the 2025 Atlantic hurricane season.

Environmental conditions remain broadly favorable for further intensification as the system moves west-northwest at about 15 mph, though high wind shear and potential interaction with a subtropical ridge could influence its eventual track and intensity.

Outlook: Residents and mariners along Mexico’s Pacific coast and in parts of the Baja California peninsula should continue monitoring official updates for both Kiko and Lorena, while interests in the eastern Atlantic basin should watch for potential tropical-storm formation later this week.
