Conclusion:   Normal Weather Situation

The the trough of low pressure cell covered over the lower North of Viet Nam lies across Thailand, Lao PDR, Cambodia and Viet Nam. The rather strong Southwesterly winds prevail over Andaman Sea, the Gulf of Thailand, Thailand and Indochina Peninsular at the surface. The Southwesterly winds prevail over Myanmar, Thailand and Indochina Peninsular at the height of 1.5km (850 hPa).

On June 03-05 2014, the trough of low pressure cell covered over the lower North of Viet Nam will continue lying across Myanmar, Thailand, Lao PDR, Cambodia and Viet Nam. The rather strong Southwesterly winds prevail over Myanmar, Thailand and Indochina Peninsula.  

 

As the result of these phenomena, it will bring moderate rain shower with isolated heavy rain will be likely in more areas in the Northeast, the Central and the East of Thailand, the North, the Northeast, the Central, the South and the East of Cambodia, the Central and South of Lao PDR and Viet Nam  during 03-04 June 2014.
