HURRICANES
• Hurricanes can get HUGE, some even 600 miles across ways and can go up to 75-200kph
• Usually Hurricanes last up to a week and can go up to 10-20km in an hour over open oceans or seas
• DID YOU KNOW? Hurricanes start in the sea, but only if the water is 26c or warmer
TORNADOES• Tornadoes are rotating rows of air sometimes coming after a
thunderstorm• They pretty much destroy anything in it’s way and they can go
up to 300kph!!• They are formed when a nice moist air and cool, dry air meet.
When they do, they make instability in the air. There is a change of wind direction and wind speed.
• On Tuesday there was one in Auckland.

HAIL• Hail is formed when rain drops are caught in an updraft of a
thunderstorm. They get lifted high into the sky and they get so high that they turn into ice
• They start to get heavy so that’s why the fall down.
• The little hail pieces get lifted up again so they get bigger.
Biggest Hail piece ever
FLOODS• Floods are caused by a couple of days of heavy rain, making
the rivers overflow and the water hits the nearest town
• Sadly there was a flood out in Waimarama and Ocean Beach.
