BANGKOK, July 1 (Xinhua) -- The Thai Meteorological Department said on Monday that heavy rains are expected from Tuesday in north and northeastern part of Thailand due to the buildup of a low pressure system, which may intensify the southwest monsoon.
The early period of July will see increased precipitation in the northern and northeastern regions, and high waves in the Gulf of Thailand and the Andaman Sea, the department said in a statement.
However the statement said the central, eastern, and southern regions will experience more precipitation but not as much as in the northern and northeastern regions.
The Meteorological Department's Director General Phuwieng Prakhammintara also warned Bangkok residents of heavy rains which may lead to heavy flooding in the capital city.
"Bangkok will see increased precipitation affecting over 40-60 percent of the area, usually in the afternoon and at night," said the statement. "The Andaman Sea will experience 2-3 meters of high waves, while in the Gulf of Thailand - off the coast of Rayong, Chanthaburi, and Trat - 2-meter-high waves are expected."
Phuwieng said generally the average temperature in this period will be 33 degrees Celsius, with the average temperature in Bangkok expected to be 37 degrees Celsius while other parts of the Central region will experience 32-36 degrees Celsius.
