Current Snapshot

The Pacific Disaster Center’s (PDC Global) Tuesday, September 22, 2026, Tropical Cyclone Activity Report…for the Pacific Ocean, the Indian Ocean, and adjacent Seas.

Tropical Cyclones

Tropical Cyclone 16E (Odalys) is located about 1455 miles west-southwest of the southern tip of Baja California

Tropical Cyclone 17E (Polo) is located about 345 miles south-southeast of Manzanillo, Mexico

Tropical Cyclone 24W (Dujuan) is located approximately 424 NM east of Misawa, Japan – Final Warning

Northeast Pacific:   

Tropical cyclone 16E (Odalys)  

ODALYS MAINTAINS INTENSITY AS IT MOVES OVER THE OPEN EASTERN PACIFIC OCEAN

According to the NHC advisory number 10

Odalys is moving toward the north near 5 mph (7 km/h). A turn toward the northeast and then east-northeast is expected to occur over the next day or so. An east-northeast to eastward motion is expected through the end of the week.

Maximum sustained winds are near 65 mph (100 km/h) with higher gusts. Additional strengthening is forecast, and Odalys could become a hurricane later today or tonight.

Tropical-storm-force winds extend outward up to 90 miles (150 km) from the center. The estimated minimum central pressure is 998 mb (29.47 inches).

SURF: Swells generated by Polo are expected to affect portions of the coast of southwestern Mexico during the next few days. These swells are likely to cause life-threatening surf and rip current conditions.

>>> South of the Gulf of Tehuantepec:

An area of low pressure is expected to form in the next few days to the south of the Gulf of Tehuantepec. Afterwards, environmental conditions should be favorable for gradual development, and a tropical depression could form late this week or this weekend as the system moves slowly west-northwestward to northwestward. This motion should keep it parallel to the coast of southern and southwestern Mexico.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…medium…60 percent

Central North Pacific: There are no Tropical Cyclones

>>> Southeast of the Hawaiian Islands:

(Former TD 15E)

The remnants of Tropical Depression 15E, located several hundred miles southeast of the Hawaiian Islands, has produced an increase in showers and thunderstorms over the last few hours. The environmental conditions are still expected to be conducive for further development, and a tropical depression is likely to form during the next day or two while the system moves slowly west-northwestward or northwestward. Interests in the Hawaiian Islands should continue to monitor the progress of this system.

* Formation chance through 48 hours…high…70 percent
* Formation chance through 7 days…high…90 percent

Tropical Cyclone 24W (Dujuan) – Final Warning

According to the JTWC warning number 28…sustained winds were 60 knots with gusts to 75 knots

Animated multi-spectral imagery depicts tropical storm 24W (Dujuan) with a very broad, elongated, and fully exposed low-level circulation center. Convection is highly sheared to the northeast as the system further embeds itself under the upper level jet.

Environmental analysis reveals a hostile environment characterized by cold (23-24 c) sea surface temperatures, extreme (60-65 kts) vertical wind shear, extensive dry air entrainment. 24W is assessed to be currently undergoing extratropical transition (ett), exhibiting moderate temperature advection induced by interaction with the jet.

Global deterministic models are in strong agreement that 24W will complete ett within 12 hours and continue tracking poleward through the remainder of the forecast period.

>>> There’s an area of disturbed weather that’s being referred to as Invest 91W, which is located approximately 173 NM west-southwest of Guam

Multi-spectral satellite imagery (msi) and a 220035z metop-c ascat pass depict a consolidating low level circulation center (llcc) obscured by flaring, patchy convection.

Environmental analysis indicates a favorable area for development with low vertical wind shear (10-15kts), good equatorward outflow, and a warm sea surface temperature (29-30c).

Global deterministic and ensemble models depict formation of a tropical depression within 24 to 48 hours as the system tracks northwestward.

Maximum sustained surface winds are estimated at 18 to 23 knots.

Minimum sea level pressure is estimated to be near 1006 mb.

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

>>> There’s an area of disturbed weather that’s being referred to as Invest 95B, which is located approximately 169 NM east of Visakhapatnam, India

Animated multi-spectral satellite imagery (msi) satellite imagery depicts a consolidating low-level circulation center (llcc) with flaring deep convection to the on the western periphery of the circulation.

Environmental analysis indicates a favorable area for development with low vertical wind shear (10-15 kts), moderate equatorward outflow aloft, warm sea surface temperatures (29-30c), and robust amounts of moisture within the area.

Global deterministic and ensemble models are in agreement of gradual development within the next 24-36 hours while slowly drifting towards the coast of eastern India.

Maximum sustained surface winds are estimated at 28 to 33 knots.

Minimum sea level pressure is estimated to be near 998 mb.

The potential for the development of a significant tropical cyclone within the next 24 hours is upgraded to high.
