From midday to late afternoon on May 11th in Ho Chi Minh City, there were many clouds and intermittent weak sunshine.

From noon to late afternoon, there will be occasional rain and showers in many areas, with scattered moderate rain and thunderstorms, and locally heavy rain concentrated along the western border; scattered rain is expected in the eastern coastal area. During thunderstorms, be wary of tornadoes, lightning, strong gusts of wind, and hail.

Explaining the overcast and dark cloud cover throughout the day, a representative from the Southern Vietnam Regional Meteorological and Hydrological Station stated that the cause was a weak strengthening of the continental cold high-pressure system, shifting eastward and southward. A low-pressure trough, with its axis at approximately 11-13 degrees North latitude, formed a convergence zone of winds directly over the northwestern part of the Southeastern region. At higher altitudes, a subtropical high-pressure system passed through the North Central and Northern regions of Vietnam.
