Tropical Depression Mangkhut Update #5 (FINAL)

Issued (02 UTC) 10am PhT 080813

Mangkhut has now weakened to a Tropical Depression and is rapidly dissipating after making landfall in Vietnam. The system was last located approximately 220km west southwest of Hanoi, Vietnam or about 280km northeast of Vientiane, Laos. Maximum sustained winds are now down to 45kph with gusts of up to 65kph. TD Mangkhut is moving west northwestward at 20kph.

Latest satellite image shows that the circulation of Mangkhut still remains intact and even convective activity is still somewhat good. Core and the banding is still present  as well. However, due to the fact that the system has made landfall, we expect it to continue dissipate later tonight.

Tropical Depression Mangkhut is now crossing into Laos and will continue moving west northwestward today. Rains will linger in the region through the next 24 to 48 hours. Some stations in Vietnam and Laos are already reporting 50 to 100mm of rain; up to 100mm could still fall today and into tomorrow.

This will be our final update on TD Mangkhut. Rest of the Western Pacific basin is currently cyclone-free. However, we are monitoring two low-pressure areas which low chances of becoming tropical cyclones. We'll have an update on those disturbances later today.
