strengthening with continuous rainfalls in the country and isolated heavy to
very heavy rains in the North, the Central, the East and the South regions.
People in the areas should beware of heavy to very heavy rains and
accumulations that may cause flash flood and overflows, especially along

In the lower Andaman Sea from Krabi downward and the upper Gulf, the waves are
expected about 2 meters high and above 2 meters high in thundershowers. All
ships should proceed with caution and keep off thundershowers, small boats in
the upper Andaman Sea keep ashore.
