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

Maximum Sustained Winds (1-min. avg) have decreased to near 110 km/hr (60 knots) with higher gusts. PAKHAR is forecast to maintain its strength during the next 12 hours & weaken.

Tropical Storm Force Winds (62-117 km/hr) extend outward up to 165 kilometers (90 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 MORNING:  Slowly weakens as it approaches the coast of Southern Vietnam [8AM APR 01: 10.0N 108.1E @ 100kph].
MONDAY MORNING:  Loses Tropical Cyclone status...just an area of low pressure while moving across the land mass of Southern Vietnam (crossing the VIetnamese-Cambodian Border) [8AM APR 02: 11.3N 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 - over water (South China Sea)...not yet affecting land areas. 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).
12-18HR TOTAL RAINFALL ACCUMULATION - from 5 up to 100 mm (low to high rainfall) can be expected along areas affected by the outer & inner rainbands (see above)...with isolated amounts of 101 to 150 mm (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.
