TD Washi Update #13 [FINAL]

Tropical Depression Washi is now rapidly disintegrating in the South China Sea, just east of Vietnam. The storm was last located approximately 340km east of Ho Chi Minh. Maximum sustained winds are around 45kph gusting to 70kph. It is moving westward at 20kph.

The system is now weakening with convective activity almost gone. The circulation center is also becoming less defined, as seen on an ASCAT pass. A new surge of the NE Monsoon is bringing moderate wind shear and drier air. JTWC and JMA have both given their respective final warnings for the storm. As such this will also be our final update for TD Washi.

Washi's remnants could affect Southeastern Vietnam with scattered rain showers. Rainfall amounts should generally be light, however.

As the Tropical Season is nearing its end, we will revert back to giving 3x a week updates regarding the weather in the region. As always, we'll keep monitoring the Pacific for possible cyclone development.
Issued (2130 UTC) 530am PhT 122011
