Catawba rhododendron bushes can reach a height of 6'-8' with a spread of 4'-6'. Displays are most effective when rhododendron bushes are massed together. These are poisonous plants -- do not allow children to ingest any of the azaleas or rhododendrons.
Best Answer: Tornadoes are caused by winds. When a tornado forms the wind pressure around the tornado drops and that's what you see on the barometer, the pressure goes down.
The condensation also creates all the rain that generally comes with a hurricane. The heat that's produced from the condensation warms the air, which causes it to rise. As it rises, it sucks up surface-level air and creates the low-pressure eye of the storm.
