General weather patterns
During the week from 27th Aug to 03rd Sept 2019, the weather outlook bulletins and maps issued by the Thailand Meteorology Department (TMD) were used to verify the weather condition in the LMB. The low pressure was observed at the middle part of LMB (Khong Chiam/ Pakse and the 3S area), which attracted rainfall in these locations during this week. The abundant rainfall often occurs at the end of August and early September with more rain amount than previous months due to the tropical cyclones of PUDOL tracking from Vietnam. Additionally, some tropical cyclone was moved and toward the central highland of Vietnam and will hit the Vietnam and middle part of the LMB at the end of August and early September 2019. Figures 1 & 2 presented the weather map for 31 th Aug and 03 rd Sept 2019.
