Current Snapshot

The Pacific Disaster Center’s (PDC Global) Tuesday, August 13, 2024, Tropical Cyclone Activity Report…for the Pacific Ocean, the Indian Ocean, and adjacent Seas

Current Tropical Cyclones:

Tropical Cyclone 07W (Son-tinh)…is located approximately 292 NM southeast of Misawa, Japan – Final Warning

Tropical Cyclone 08W (Ampil)…is located approximately 559 NM south of Yokosuka, Japan

Tropical Cyclone 09W (Wukong)…is located approximately 356 NM east-northeast of Chichi Jima, Japan

Northeast Pacific Ocean: There are no Tropical Cyclones

>>> Offshore Southwestern Mexico:

An area of low pressure could form this weekend well offshore of southern Mexico. Some slow development is possible by early next week as the low moves west-northwestward, remaining offshore of southwestern Mexico.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…low…20 percent

Central North Pacific: There are no Tropical Cyclones

Western Pacific, Indian Ocean and adjacent Seas:

Tropical Cyclone 07W (Son-tinh) – Final Warning

According to the JTWC Warning number 6, sustained winds are 25 knots with gusts to near 35 knots

Animated enhanced infrared imagery shows a general broadening of the low level circulation center indicating wind field weakening. Additionally another pass shows maximum winds of 25 knots, confined to the southeastern quadrant of the llcc.

The system is expected to track generally northward and fully dissipate within 24 hours prior to reaching the eastern coast of Hokkaido.

Tropical Cyclone 08W (Ampil)

According to the JTWC Warning number 7, sustained winds are 60 knots with gusts to near 75 knots

Animated multi-spectral satellite imagery depicts a llcc fully obscured by a recently developed cdo. The lack of recent microwave imagery precludes an accurate assessment of the low level structure, but it is assumed that the previously documented precession of the vortex is continuing with vertical alignment of the vortex from its previously southwardly tilted structure.

The system presently is associated with spiral bands of convection primarily to the east and south, with an intense and quick development of a cdo feature.

Analysis reveals a favorable environment with very warm sea surface temperatures, good equatorward outflow and low vertical wind shear.

Tropical Cyclone 09W (Wukong)

According to the JTWC Warning number 5, sustained winds are 30 knots with gusts to near 40 knots

Animated enhanced infrared satellite imagery shows the system has expanded with fragmented and short formative bands wrapping tighter into the low level circulation (llc) that is obscured by the central dense overcast (cdo). This system is the third in a series of tropical cyclones tracking poleward along the eastern rim of a monsoon gyre.

Analysis indicates a marginally favorable environment with warm sea surface temperatures and moderate ventilation offset by moderate vertical wind shear and convective subsidence associated with an upper level low to the north.
