At about 4:30 p.m. this afternoon, July 19, in Hanoi and some neighboring provinces, black clouds will reach over the area, then the weather will turn to thunderstorms and strong gusts of wind.

Previously, at 4:10 p.m., the National Center for Hydro-Meteorological Forecasting issued a warning, through monitoring on satellite images, thunderstorm location data and weather radar, it was discovered that convective clouds were developing and causing rain in the northern area of Hanoi, moving and expanding to the inner city of Hanoi. During thunderstorms, there is a possibility of tornadoes, lightning and strong gusts of wind. The warning level of natural disaster risk due to tornadoes, lightning, and hail is level 1.
Many people expressed concern about whether this was rain due to storm No. 3 Wipha because the storm is moving rapidly and tends to strengthen.
Regarding this issue, according to Mr. Mai Van Khiem - Director of the National Center for Hydro-Meteorological Forecasting, thunderstorms accompanied by strong winds in Hanoi and the northern provinces this afternoon (July 19) are not due to the circulation of storm No. 3 Wipha. These are just common thunderstorms when the North is in the rainy season. The western edge of the storm's circulation may cause thunderstorms before the storm on our mainland from tomorrow evening and night, July 20.
"The reason for this afternoon's thunderstorms in the North is due to the convergence of winds along the low trough crossing the North in the Northwest - Southeast direction" - Mr. Khiem analyzed.
Tomorrow, July 20, Hanoi will be hot and sunny with the highest temperature of about 34 - 36 degrees Celsius, with occasional showers and thunderstorms in the evening and at night, and some places will have heavy rain.
