Severe weather such as thunderstorms, tornadoes, hurricanes, and blizzards can endanger people and cause property damage. Thunderstorms produce heavy rain, lightning, thunder, and sometimes hail. Tornadoes are violent whirling winds that can destroy buildings. Hurricanes are powerful storms that form over warm oceans and can demolish structures. Blizzards occur in winter when winds blow heavy snow, reducing visibility. It is important to take safety precautions like sheltering indoors during storms and listening for watches and warnings.

2. Severe Weather Severe weather poses danger to people, structures, and animals.

3. Thunderstorms Heavy rains, Lightning Flashes, Thunder Roars, And Hail falls during a thunder storm. When rising air, water vapor condenses into water droplets or ice crystals. Warm, moist air can be forced upward where it cools and condensation occurs, forming cumulonimbus clouds.

4. Thunderstorm Damage Thunderstorms can stall over a region, causing rain to fall heavily for a period of time. Strong winds can cause damage. Hail from a thunderstorm can dent cars and aluminum siding on houses.

5. Lightning and Thunder A typical bolt of lightning can immediately heat the air to between 15,000 to 60,000 degrees Fahrenheit. (That's hotter than the surface of the sun!) It's that explosion of air that creates sound waves, which we hear and call thunder. Lightning always produces thunder.

6. Tornadoes Some of the most severe thunderstorms produce tornadoes. A violent, whirling wind that moves in a narrow path over land. A tornadoes' destructive winds can rip apart buildings and uproot trees.

7. Hurricanes The most powerful storm. A large, swirling, low-pressure system that forms over the warm Atlantic ocean. Hurricanes can destroy crops, demolish buildings, and kill people and other animals.

8. Blizzards If the winds are 56 km/h, the temperature is low, the visibility is less than 400 m in falling or blowing snow, and if these conditions persist for three or more hours. Occurs in the winter.

9. Severe Weather Safety Take cover inside thunderstorms. Listen to the tornado watch and the warnings and go to a shelter. Go to a hurricane center. Listen to the weather coverage on news and prepare for anything. For lightning, just stay indoors
