General weather patterns

During the week from 03rd to 09th 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, which attracted rainfall during this week. The abundant rainfall often occurs at the end of August and early September with more rain amount than previous months. They stated that some tropical cyclones sometime develop at the western side of the northern Pacific Ocean and move northwest and pass to the South China Sea. Consequently, LMB will meet abundant rainfall with heavy to very heavy rain amount at some areas. Figures 1 & 2 presented the weather map for 05th and 09 th Sept 2019.
