The Provincial Hydrometeorological Station emphasized that on days with thunderstorms, people need to be especially wary of tornadoes, lightning, hail and strong gusts of wind. These are extreme weather patterns that can cause heavy damage to agricultural production, causing trees to fall, damage to houses, infrastructure and transportation works.
In addition, localized heavy rain poses a high risk of causing floods, flash floods and landslides, especially in areas with steep terrain, along rivers and streams, hillsides and areas under construction. Low-lying areas also need to have proactive plans to prevent flooding.
Functional agencies recommend that temperature differences, cold weather at night and early morning can adversely affect human health, especially paying attention to keeping warm for the elderly and children.
In addition, heavy rain reduces visibility, causing slippery roads, so people need to be very careful to avoid accidents when participating in traffic.
