A broad and elongated area of low pressure located several hundred miles southwest of the southern tip of the Baja California peninsula continues to produce disorganized showers and thunderstorms. Environmental conditions are somewhat conducive for development, and a short-lived tropical depression could form on Thursday or Friday while the low moves generally northwestward at 10 to 15 mph. This system is forecast to move over cooler waters and into an environment of stable air and strong upper-level winds this weekend, which should inhibit further development.

* Formation chance through 48 hours…low…20 percent
* Formation chance through 5 days…low…20 percent

Tropical Cyclone 21W

https://www.metoc.navy.mil/jtwc/products/21W_230000sair.jpg

Sustained 30 knot winds…with gusts to 40 knots (as of Warning Number 3)

Here’s what the computer models are showing for Tropical Cyclone 21W

According to the JTWC…satellite imagery depicts a rapidly consolidating system with flaring deep convective blooming over the assessed low level circulation center over the past six hours.

The system lies in a favorable environment characterized by low wind shear, warm sea surface temperatures, and moderate equatorward and weak poleward outflow.

The system is expected to make landfall along the central Vietnam coastline around 24 hours, to the south of Da Nang. Conditions are generally favorable for intensification with the only limiting factors being the modest, single channel outflow and limited time available prior to landfall.

TD 21W is expected to intensify at a climatological rate to a peak of 35 knots at or just prior to landfall near 24 hours. Once inland the system will rapidly
dissipate by 48 hours over eastern Thailand due to terrain interaction.

 

Tropical Cyclone 20W

https://www.metoc.navy.mil/jtwc/products/20W_230000sair.jpg

Sustained 30 knot winds…with gusts to 40 knots (as of Warning Number 3)

Here’s what the computer models are showing for Tropical Cyclone 20W

According to the JTWC…satellite imagery depicts a broad and still somewhat elongated, but quickly consolidating low level circulation center. An area of symmetrical deep convective activity has rapidly developed over the past six hours, though as of yet, there are no signs of the development of distinct banding feature.

TD 20W is in a highly favorable environment characterized by very warm waters, and low (5 knots or less) wind shear. While upper-level outflow is assessed as strong both poleward and equatorward, it is somewhat constrained to poleward by the presence of a sharp, east-west oriented low that lies roughly along the 20th parallel.

The system is forecast to track over or very close to the island of Guam by  24 hours. Over the next 24 hours, TD 20W is forecast to steadily intensify to 45 knots prior to its closest pass to Guam under favorable conditions.

Combined with the expected development of a anticyclone over top of the system by 24 hours, the very warm sea surface temperatures and passage over a pool of very warm water to the northwest of Guam, the system is expected to undergo a period of rapid intensification once it moves past the Marianas, reaching a peak of 120 knots by 96 hours. Increased mid-level shear and slightly less optimum outflow aloft will result in steady intensity through 120 hours.
