The Pacific Disaster Center’s (PDC Global) Thursday, December 11, 2025, Tropical Cyclone Activity Report…for the Pacific Ocean, the Indian Ocean, and adjacent Seas

Current Tropical Cyclones:

Tropical Cyclone 07S is located approximately 267 NM north-northeast of the Cocos Islands

Northeast Pacific Ocean: There are no Tropical Cyclones

The last regularly scheduled Tropical Cyclone Activity Report of the 2025 eastern North Pacific Hurricane Season has been issued. Routine issuance of this section of the PDC product will resume on May 15, 2026. During the off-season, Special Tropical Weather Outlooks will be issued as conditions warrant by the NHC.

Central Pacific Ocean: There are no Tropical Cyclones

The 2025 central North Pacific hurricane season has ended. As such, the final routine Tropical Cyclone Activity Report for the 2025 season has been issued. Routine issuance of this section of the PDC product will resume on June 1, 2026. During the off-season, Special Tropical Weather Outlooks will be issued as conditions warrant by the CPHC.

Western Pacific, Indian Ocean, and adjacent Seas:

South Indian Ocean

Tropical Cyclone 07S

Animated enhanced infrared (eir) satellite imagery depicts tropical cyclone 07S becoming better defined with increased convective activity especially throughout the southwestern quadrant and cooling cloud top temperatures near the center of the circulation.

Environmental analysis depicts a favorable environment for development with sea surface temperatures between 28 c and 29 c, low vertical wind shear (10-15 kts), and good outflow.

Initially TC 07S will track southwestward along the northwestern periphery of the subtropical ridge centered to the southeast, while continuing to strengthen and consolidate. After 60 hours the system is forecast to enter a region of the southern Indian Ocean encountering a changing steering environment. The track will be determined primarily by ridging to the east and north, affected by a passing long wave trough to the south.

Between 96 and 120 hours, another str centered to the southwest will build and begin influencing the track of TC 07S toward a more westward trajectory. In the meantime, this competing steering pattern will create a boxing scenario with the system allowed only slow and erratic movement. In addition invest 92S will come within 250-300 NM of the forecast track for TC 07S, which will further complicate the predicted track.

In terms of intensity during the second part of the forecast, the system is expected to begin weakening after 48 hours, primarily due to increasing vws, slower translational speed resulting in potential cooler water upwelling, and direct cyclone interaction with what will then be invest 97S.
