Hazards affecting land:

  • Heavy rainfall will continue to spread inland over northern Vietnam, Laos, and northern Thailand through midweek. This rainfall could cause widespread flooding. For additional information, including possible local warnings, refer to products from your local weather office.

Discussion:

Bualoi has quickly pushed inland and despite being close to the border of Vietnam and Laos, it is still a typhoon. Bualoi continues to sport a fairly impressive structure for a system so far inland, with convective hot towers flaring around the center and an eye feature still present on microwave satellite imagery. ASCAT data suggests that there are still 60-65 kt winds occurring along the coast and the latest CIMSS D-PRINT estimate was 77 kts. Accounting for decay over land, the intensity is lowered to 65 kts.

Bualoi will soon be moving over much more rugged terrain as it crosses into Laos, and this should do a number on its surface circulation. Most available model guidance loses Bualoi’s vortex within the next 24 hours, but given how resilient it has been so far, there is a 24-hour forecast point in the forecast below with an incredible intensity of 15 kts.
