Tropical Depression Haitang Update #8 (FINAL)

Tropical Depression Haitang is now beginning to dissipate over Vietnam. It made landfall earlier this morning and is now currently located approximately 470km south of Hanoi. Maximum sustained winds have decreased to 45kph gusting to 70kph. Haitang is moving westward at 20kph.

VIS Image shows that the center is no longer discernible. The storm has become fragmented now due to land interaction.

Nevertheless, Haitang is still exhibiting some pretty intense convective activity that could bring moderate to heavy rains across Vietnam, Laos, and Thailand. Latest rainfall reports from Vietnam show rain amounts of 50 to 100mm. We expect maybe another 50mm to fall tonight. Same amounts are forecast for Laos.

Haitang is forecast to begin dissipating tonight over Laos. Its remnants, however, will still bring widespread showers across Indochina for the next few days; remember that this will also enhance some monsoonal flow into the region.

JMA and JTWC have given their final updates for Haitang. Likewise, this will also be our final update for this system. For updates on TD 22W and Typhoon Nesat, please refer to our separate posts.
