The Pacific Disaster Center’s (PDC Global) Wednesday, October 29, 2025, Tropical Cyclone Activity Report…for the Pacific Ocean, the Indian Ocean, and adjacent Seas
Current Tropical Cyclones:
Post-Tropical Cyclone 18E (Sonia)…is located approximately 1180 miles west-southwest of the southern tip of Baja California – Last Advisory
Tropical Cyclone 03B Montha…is located approximately 523 NM southwest of Kolkata, India – Final Warning
Northeast Pacific Ocean:
Post-Tropical Cyclone 18E (Sonia) – Last Advisory
SONIA WEAKENS INTO A POST-TROPICAL REMNANT LOW
According to the NHC advisory number 19
The post-tropical cyclone is moving toward the west near 10 mph (17 km/h) and this general motion is expected to continue for the next day or so.
Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Additional weakening is forecast, and the remnant low is expected to dissipate in a day or so.
The estimated minimum central pressure is 1007 mb (29.74 inches).
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:
North Indian Ocean
Tropical Cyclone 03B (Montha) – Final Warning
According to the JTWC warning number 11, sustained winds are 35 knots with gusts to near 45 knots.
Animated enhanced infrared (eir) satellite imagery shows that the system has moved inland.
Swift decay is expected as the remnants track generally northwestward.
Arabian Sea
>>> There’s an area of disturbed weather being referred to as Invest 92A…which is located approximately 225 NM southwest of Jafrabad.
Enhanced infrared satellite imagery (eir) depicts a broad, poorly defined circulation with very limited convection within the low-level circulation center.
Environmental analysis reveals favorable conditions for development with moderate vertical wind shear (15-20 knots), good poleward outflow aloft, and warm sea surface temperatures (28-29 c).
Global and ensemble models are in fair agreement that 92A will track generally northward but remain broad over next 24-48 hours.
Maximum sustained surface winds are estimated at 22 to 28 knots.
The potential for the development of a significant tropical cyclone within the next 24 hours remains low.
