NALGAE (QUIEL) will move generally WNW...and this motion will persist throughout the forecast period. On the forecast track, the core of the storm will reach the southern coast of Hainan Wednesday.

Additional weakening is expected within the next 12 to 24 hours as it continues to move over a pool of cooler water...however, re-strengthening might happen before reaching the coast of Vietnam.

Tropical Storm Force Winds (62-117 km/hr) extend outward up to 205 kilometers (110 nautical miles). NALGAE is a large-sized tropical cyclone with a diameter of 720 kilometers (390 nautical miles).
