The Southern region experienced widespread rain, with scattered moderate to heavy rain, and locally very heavy rain. Rainfall recorded in the past 24 hours (from 7 am on May 29 to 7 am on May 30) in some places such as: Truong Xuan A (Can Tho) 134.8 mm; Truong Long A (Can Tho) 112.6 mm; Thoi Lai (Can Tho) 97.2 mm; Nong truong 422 (An Giang) 90.8 mm; Gao Giong (Dong Thap) 81.6 mm; Tra Noc (Can Tho) 74 mm; Ba Hon (An Giang) 61.8 mm...
According to the Southern Regional Hydrometeorological Station, the weather pattern affecting the area is due to a low pressure trough with its axis at about 24-27 degrees North latitude connected to the hot low pressure area in the West being compressed gradually down to the South and gradually filled up by the continental high pressure area in the North; the low pressure trough with its axis at about 9-12 degrees North latitude is active.
Southwest wind in the South operates with moderate intensity. Above, the subtropical high pressure with its axis through the North tends to encroach westward, dominating the weather in the region.
Therefore, from 7 am on May 30 to 7 am on June 1, the Southern region is forecast to continue to have moderate rain, heavy rain and thunderstorms. Total rainfall is commonly from 80-15 mm, in some places over 150 mm.
Thunderstorms are likely to be accompanied by dangerous phenomena such as tornadoes, lightning, hail and strong gusts of wind.
