According to Mr. Le Thanh Hai, Deputy Director of Meteorological and Hydrological Forecasting Center, "all storms are very fast, so scientists around the world only give the earliest forecast. It's from 30 minutes to 2 hours ". So, if you are outside, avoid high ground, empty hills, running water or small puddles, individual tall trees and conductors like metal fences.

"Normally, when you see clouds in the sky suddenly dancing and darkening, the wind is blowing suddenly stopped, along with the temperature drop, the humidity in the air is high, the air suddenly becomes cool chilly, chilly, this is a sign that there is a possibility of thunderstorms and thunder, tornadoes will happen ".
