The Pacific Disaster Center’s (PDC Global) Friday, November 24, 2023, Tropical Cyclone Activity Report…for the Pacific Ocean, the Indian Ocean, and adjacent Seas

Current Tropical Cyclones:

Tropical Cyclone 20E (Ramon) is located about 1040 miles southwest of the southern tip of Baja California


Northeast Pacific Ocean:


According to the NHC advisory number 7…

Ramon is moving slowly toward the north near 5 mph (7 km/h) and this general motion is expected to continue for the next day or so. A westward turn and continued slow motion is forecast to occur by early next week.

Maximum sustained winds have increased to near 40 mph (65 km/h) with
higher gusts. A brief period of intensification is forecast followed by weakening by tomorrow night. Ramon is likely to become a remnant low by Sunday.

Tropical-storm-force winds extend outward up to 35 miles (55 km) from the center.

Central North Pacific:

There are no tropical cyclones nor any areas of disturbed weather under investigation by the Central Pacific Hurricane Center (CPHC) at the time of this writing.

Western Pacific, Indian Ocean and adjacent Seas:

There’s an area of disturbed weather being referred to as Invest 99W...located approximately 610 NM east-southeast of Phuket.

Animated multi-spectral satellite imagery depicts a broad and weak low-level circulation (llc) with some deep convective bursts displaced to the north and west of the circulation. Another image reveals 5-15 knot winds around the llc with stronger 25-30 knot winds 160 NM to the north within the northeast surge.

Environmental analysis indicates that 99W is in an unfavorable environment for development with weak outflow aloft, moderate to high (20-25 knot) vertical wind shear, and climatologically high surface pressures.

Global models are in good agreement that 99W will track northwestward over the next 48 hours. Global models have backed-off on development of the system from previous runs.

Maximum sustained surface winds are estimated at 10 to 15 knots.

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