PAKHAR (02W) is expected to turn WNW-ward over the next 1 to 2 days. On the forecast track, the core of PAKHAR will make landfall over Southern Vietnam on Sunday evening, April 1 (approx. 7-8PM HK Time), passing very close to Ho Chi Minh City early Monday morning (approx. 1-2AM HK Time). This system will traverse the land mass of Southern Vietnam through Monday morning and dissipate along the Vietnamese-Cambodian Border in the afternoon.

Maximum Sustained Winds (1-min. avg) are near 110 km/hr (60 knots) with higher gusts. PAKHAR is forecast to lose strength during the next 12 to 24 hours due to lower Ocean Heat Content (OHC) & land interaction.

Tropical Storm Force Winds (62-117 km/hr) extend outward up to 140 kilometers (75 nautical miles) from the center. PAKHAR (02W) is an average-sized tropical cyclone with a diameter of 445 kilometers (240 nautical miles).

The following is the summary of the 2-day forecast outlook on this system:

SUNDAY AFTERNOON:  Bears down the coast of Southern Vietnam...starts to weaken due to land interaction [2PM APR 01: 10.2N 108.0E @ 95kph].
MONDAY AFTERNOON:  Loses Tropical Cyclone status...just an area of low pressure moving across the land mass of Cambodia [2PM APR 02: 11.8N 105.8E @ 35kph].

*Please be reminded that the Forecast Outlook changes every 6 hours, and the Day 3 Forecast Track have an average error of 250 km...while the wind speed forecast error, averages 35 kph per day. Therefore, a turn to the left or right of its future track and changes in its wind speed must be anticipated from time to time.


Below is the summary of the storm's parts and its hazards affecting specific areas:

CENTRAL DENSE OVERCAST (CDO) - over water (South China Sea)...not yet affecting any land areas. Near-Typhoon Conditions w/ Near-Typhoon Force Winds (95-117 kph) will be expected along the CDO. (click here to know more about CDO).
INNER RAINBANDS - affecting and spreading across the coastal areas of Southern Vietnam. Tropical Storm Conditions w/ Tropical Storm Force Winds (62-94 kph) will be expected along these bands.
OUTER RAINBANDS - affecting & spreading across Southeastern & Southern Vietnam. Cloudy/Rainy Conditions w/ moderate to strong winds (<62 kph) will be expected along these bands (click here to know more about Rainbands).
24HR TOTAL RAINFALL ACCUMULATION - from 5 up to 200 mm (low to high rainfall) can be expected along areas affected by the outer & inner rainbands (see above)...with isolated amounts of 201 to 400 mm (high to very high) along areas near the center of PAKHAR (02W). (click to open NOAA's eTRaP graphic).
COASTAL STORM SURGE FLOODING - possible 1-3 ft [0.3-0.9 m] above normal tide levels...accompanied by large and dangerous battering waves can be expected along the coastal, inland lakes and beach front areas of Southern & SE Vietnam beginning Saturday until its projected landfall on Sunday. Very minimal damage is likely on this type of storm surge. Danger from Rip Currents or Rip Tides can be expected along the beach-front areas of Spratly Islands & other coastal areas of Vietnam.
