Geography in the news- Tornadoes in Texas and Oklahoma

Forecasters had predicted a, “major severe weather outbreak,” on Monday 20th May 2019 in Texas and Oklahoma (USA) including a series of violent tornadoes. The tornadoes were expected to be the worst for two years, so more than 150,000 school children were allowed to stay home as a precaution and residents were urged to take shelter.

Severe thunderstorms did hit parts of Texas and Oklahoma on Monday evening, producing small tornadoes, but as of early Tuesday the region appeared to have been largely spared from the destructive weather that had been feared by forecasters!

After this however severe thunderstorms did drench and flood parts of Oklahoma on Tuesday and enormous hail stones the size of limes fell!

Weird, wild and wonderful weather!

Tornadoes are sometimes called twisters. If a tornado happens over water it is called a waterspout. Not all tornadoes can be seen but their high wind speeds and fast rotation often form a funnel of water.

The Fujita Scale is used to measure the strength of tornadoes. F0 tornadoes cause very little damage whereas F5 tornadoes cause massive damage.

Many tornadoes have wind speeds less than 100 miles per hour (161 km per hour) but  more serious tornadoes can reach wind speeds of over 300 miles per hour (483 km per hour).

The country that has the most tornadoes is the USA, with about 1200 tornadoes every year. Most of these occur in an area nicknamed ‘Tornado Alley’. The US States most frequently hit by tornadoes are: Texas, Kansas, Oklahoma and Florida.

The deadliest tornado ever recorded in the world was in 1989 in Bangladesh, which killed 1300 people

In the southern hemisphere tornadoes usually rotate in a clockwise direction, but in in the northern hemisphere tornadoes usually rotate in an anti-clockwise direction!
