As August 2025 unfolds, at Silurian, we track the two latest storms across different ocean basins—Tropical Storm Henriette in the Pacific and Hurricane Erin in the Atlantic. We see these contrasting storms as not just weather events, but a real-time demonstration of the unique dynamics of each ocean basin and a powerful showcase for the predictive capabilities of GFT’s advanced Earth modeling.
Tropical Storm Henriette formed in the Eastern Pacific and had been making headlines for its track east of Hawaii, with forecasters confirming it poses no threat to land but severe conditions in the open sea. As of mid-August, Henriette transitioned to a post-tropical cyclone with maximum sustained winds of 40 knots and was moving northwest, and started dissipating.
The storm's path represents a classic Pacific tropical cyclone trajectory—forming in the warm waters off Mexico's coast and gradually curving northward into cooler waters where it eventually weakened and transitioned to an extratropical system. A large ridge over the north-central Pacific guided Henriette on its fast northwestward track, demonstrating how atmospheric steering patterns shape storm paths.
GFT-C, Silurian’s proprietary forecasting system for Tropical Cyclones, was predicting the fate of Henriette 2 days earlier than the official forecast, providing crucial early intelligence for maritime operations
Meanwhile, in the Atlantic, Hurricane Erin has the opposite evolution, continuously intensifying. Erin became the first Atlantic hurricane of 2025 and rapidly intensified into a major hurricane. The storm became one of the fastest-rapidly intensifying storms in Atlantic history, showcasing the explosive development potential of Atlantic tropical systems.
In just 24 hours, Erin’s maximum winds rocketed from 75 mph to 160 mph, reaching Category 5 status. Though it has since fluctuated between Category 3 and 4 strength, it remains a significant, major hurricane. The National Hurricane Center and local forecasting officers are warning of life-threatening surf and rip currents for the Caribbean Islands and the U.S. East Coast, prompting evacuation orders in the coastal Carolinas.
Silurian, with GFT-C, provided one of the earliest track forecasts of Erin, indicating that the TC would not land on the CONUS, and would continue moving north / northeast,
where it would eventually dissipate in the N. Atlantic, with every updated forecast cycle confirming the earlier forecasts by Silurian.

The contrasting behaviors of Henriette and Erin highlight the fundamental differences between Pacific and Atlantic tropical cyclone seasons. Pacific storms like Henriette often have longer tracks over open water, while Atlantic systems like Erin can rapidly intensify in the warm, low-shear environment of the tropical Atlantic.
As we navigate the peak of hurricane season, Henriette and Erin serve as a powerful reminder of how tropical cyclones vary. They also serve as a validation of how advanced AI systems, such as GFT-C, trained on PBs of global storm data archives, are changing the game. By forecasting storm trajectories with greater accuracy and predicting their ultimate fate sooner, we can better understand and prepare for the unique story each new storm has to tell.
