Here’s what the computer models are showing…for what’s being referred to as Invest 98E Environmental conditions are still forecast to be somewhat conducive for gradual development, and a tropical depression could form early next week as the system moves slowly west-northwestward or northwestward away from the coast of Mexico. By late next week, conditions are expected to become unfavorable for further development. * Formation chance through 48 hours…low…30 percent * Formation chance through 5 days…medium…50 percent Here’s a link to the National Hurricane Center (NHC)

However, the system is drifting over cool sea surface temperatures…which are offsetting the favorable outflow and warm seas. TY Vamco will continue on its west-northwestward track, making landfall over central Vietnam northwest of Hue shortly after 12 hours. After landfall, the rugged terrain will rapidly erode the system down to 35 knots by 24 hours, and dissipation is expected by 36 hours…after it crosses Vietnam, central Laos, and into Thailand.

Tropical Cyclone 01S (Alicia)

Here’s what the computer models show According to the JTWC, the system is in a favorable environment, with low 10-15 knot wind shear, and strong westward and poleward outflow, and warm sea surface temperatures. The favorable environment will fuel steady intensification to a peak of 70 knots at 24-36 hours. Afterward, increasing wind shear and cooling sea surface temperatures will gradually erode the cyclone  toward dissipation by 120 hours.

Models are in good agreement that the system will continue to track westward towards Diego Garcia over the next hours, although with minimal intensification due to the hostile shear environment. Maximum sustained surface winds are estimated at 20-25 knots. The potential for the development of a significant tropical cyclone within the next 24 hours remains medium.
