How to recognize early thunderstorms, cyclones, hail

The tornado formed by very strong convection in the air, could be accompanied by lightning or tornadoes, hail, with strong gusts of wind.

The cloud in the sky suddenly began to dance and black was a sign of thunder and thunder.

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 ".

For, if you see clouds that look like dark black breasts almost cover your eyes, then seeing the strong wind rise creating constant buzzing and noise, be wary of hail. If there are then some sprinkling of raindrops, the cold air temperature goes quickly, and this time hail will appear.
