Current storm information:

  • Position: 18.0°N 106.5°E

  • Movement: NW at 15 knots (25 km/h)

  • Intensity: 70 knots (130 km/h) [Category 1]

  • Central pressure: 977 hPa

Trend:

  • Rapid weakening is forecast during the next 24 hours.

Watches and warnings:

  • There are no coastal watches or warnings in effect.

Hazards affecting land:

  • Typhoon conditions - destructive winds, heavy rain, and life-threatening flooding - are possible in northern and central Vietnam and along the southern coast of Hainan Island through late tonight. In addition, heavy rainfall will likely spread inland over Laos and northern Thailand through midweek. This rainfall could also cause widespread flooding. For additional information, including possible local warnings, refer to products from your local weather office.

Discussion:

Satellite imagery indicates that Bualoi has just made landfall in Vietnam northwest of Da Nang within the past 30 minutes. All indications are that Bualoi failed to strengthen as it crossed over the Gulf of Tonkin. Although microwave satellite imagery indicates that a very large eye feature had developed around the circulation center, convection within the eyewall and the CDO remains fragmented due to persistent northerly subsidence over the system associated with a strong upper-level ridge centered over eastern India and Bangladesh. The intensity remains 70 kts, hedged between pre-landfall Dvorak fixes of T4.0 to T4.5 but slightly lower than a D-PRINT estimate of 81 kts.

Now that Bualoi has made landfall, it should weaken rapidly as it races further inland. Bualoi should weaken to a tropical storm within the next few hours, and the circulation will likely decay into a trough over northern Laos on Tuesday. Even though the circulation of Bualoi should dissipate quickly, it remains a significant rainfall hazard for portions of Vietnam, Laos, Thailand, and Myanmar during the next several days.
