Above, the subtropical high pressure with an axis over the Central region will operate with relatively stable intensity.
The weather in the region from December 2-7 is likely to have scattered rain with some places having moderate rain, locally heavy rain. The highest temperature is 30-33 degrees Celsius, the lowest is 21-25 degrees Celsius, in the North East 20-21 degrees Celsius.

Around mid to late week, the low pressure trough with an axis at about 4-7 degrees North latitude will lift its axis to the North with the possibility of a low pressure area appearing in the South China Sea.
It is necessary to guard against the possibility of the low pressure area strengthening into a tropical depression or storm, causing dangerous weather at sea and widespread thunderstorms on land in the region.
