Specifically, the Northern and North-Central regions are forecast to experience large-scale rainfalls between 150 mm and 300 mm from now to May 25.
The rainfall will gradually decrease across the Northern and North-Central provinces and cities but brief spells of large-scale rain and thunderstorm will remain for several days later. The increasingly-operated southwest monsoon is predicted to bring thundery downpours in the Central Highlands and Southern regions at nighttime.
