Tropical Cyclone 09W (Wipha) – Final Warning

According to the JTWC warning number 16 sustained winds are 35 knots with gusts to near 45 knots

Animated multi-spectral imagery reveals the exposed low-level circulation center (llcc)as the system has continued to decapitate over the last six hours. The initial position in the Red River delta region is made with high confidence due to the exposed nature of the circulation.

The system will continue to dissipate over land during the next 24 hours while driven westward on the southern periphery of the subtropical ridge to the north.

Tropical Cyclone 10W (Francisco) 

According to the JTWC warning number 4 sustained winds are 30 knots with gusts to near 40 knots

Animated enhanced infrared (eir) satellite imagery depicts tropical depression 10W slowly consolidating as deep convective bands wrap inward from the southwest and southeast. An upper-level trough to the northwest both applies pressure to the northwest quadrant and poleward upper level diffluence.

The poleward outflow is complemented by equatorward diffluence, allowing for favorable dual-channel outflow. The initial position is placed with high confidence based on the aforementioned animated msi, and a metop-b ascat image which partially reveals the low-level circulation center bounded by 25 knot winds to the east.

A deep-layer ridge to the east will steer TD 10W north-northwestward along the northern edge of the monsoonal flow for the next 36 hours. Between 36-48 hours, the primary steering mechanism will transfer to the subtropical ridge centered over Japan, curving northwestward. Between 48-72 hours, an approaching upper-level trough will cause TD 10W to become shallow and the wind field will become broad. The monsoonal flow will close off, developing into a monsoon depression over the East China Sea, and ultimately causing TD 10W to weaken and dissipate into the larger monsoonal flow.

The system will intensify during the first 36 hours of the forecast while in a favorable environment of upper-level divergence, low vertical wind shear, and warm sea surface temperatures. Dry air will entrain into the circulation after 36 hours and an approaching upper-level trough will introduce unfavorably high vertical wind shear, initiating a weakening period. The system will dissipate into the strong monsoonal flow, ending the forecast at 30 knots.

Tropical Cyclone 11W 

According to the JTWC warning number 1 sustained winds are 30 knots with gusts to near 40 knots

>>> There’s an area of disturbed weather being referred to as Invest 98W, which is located approximately 248 NM east-southeast of Guam

Animated multi-spectral satellite (msi) imagery depicts a broad low level circulation center (llcc) with flaring convection, and low level convergence from the southern quadrant wrapping around the llcc near Guam.

Environmental analysis reveals favorable conditions for development with moderate vws (vertical wind shear), warm sst (sea surface temperatures) and good equatorward outflow aloft.

Global models agree on steady development and a northwestern track steering towards Japan within a 24-36 hour period.

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

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