The Pacific Disaster Center’s (PDC Global) Thursday, June 26, 2025, Tropical Cyclone Activity Report…for the Pacific Ocean, the Indian Ocean, and adjacent Seas

Current Tropical Cyclones:

There are no Tropical Cyclones at the time of this writing

Northeast Pacific Ocean: There are no Tropical Cyclones

Offshore of Central America and Southern Mexico:

Invest 95E

>>> Showers and thunderstorms associated with a broad area of low pressure located a few hundred miles southwest of the coast of Guatemala is beginning to show some signs of organization. Environmental conditions are expected to become more conducive for development during the next few days, and a tropical depression is likely to form by late this weekend while the system moves slowly west-northwestward, off the coast of southern Mexico.

* Formation chance through 48 hours…medium…50 percent
* Formation chance through 7 days…high…80 percent

Central Pacific Ocean: There are no Tropical Cyclones

Tropical cyclone formation is not expected during the next 7-days.

Western Pacific, Indian Ocean, and adjacent Seas:

Western Pacific

>>> There’s an area of disturbed weather being referred to as Invest 97W, which is located approximately 428 NM northwest of Guam

Animated multi-spectral satellite imagery depicts a weakly defined low level circulation (llc) with flaring convection displaced far to the southeast. Another pass reveals a broad and incomplete circulation with winds of 15-20 knots in the northern sector.

Environmental analysis for the area indicates marginally favorable conditions for development with moderate to high (20-25 knot) northwesterly vertical wind shear, warm sea surface temperatures, and moderate equatorward outflow aloft.

Global deterministic models have now shifted to depicting little to no development over the next 48-72 hours. Ensemble guidance is split with GEFS keeping the system stationary while ECENS tracks it off to the west.

Maximum sustained surface winds are estimated at 13 to 18 knots.

The potential for the development of a significant tropical cyclone within the next 24 hours remains low.
