Tornadoes, Hurricanes, and Floods

 Tornadoes are rotating columns of air that extend down from a storm cloud in the shape of a funnel.  Anything in the path of a tornado, including houses, cars, forests, and other ecosystems, are often completely destroyed. Tornadoes usually have a narrow path of destruction.  Tornadoes are formed where warm, moist air meets cool dry air. Tornadoes

F5 Tornado hit Moore in Moore, OK

Measuring Tornadoes

  Take a minute to discuss with a neighbor what to do during a tornado if you are in a house, car, or on foot.  We will take a couple of minutes to discuss, and if you have had a personal experience with a tornado we would like to hear your story! How do tornadoes form?

 Hurricanes have sustained winds of over 75 mph and form in warm, tropical waters in the Atlantic and Pacific Oceans, the Caribbean Sea, and the Gulf of Mexico.  Storm surges associated with hurricanes can lead to erosion of shorelines and destruction of coastal habitats, such as wetlands.  Hurricane Katrina, which hit New Orleans in 2005, was only a category three storm but was the most expensive (in terms of damage) and third most deadly (approximately 1,500 deaths) storm in recorded history. Hurricanes

Saffir-Simpson scale

  Take a minute to discuss with a neighbor how to prepare for a hurricane. How does this differ from how you would prepare for a tornado?  We will take a couple of minutes to discuss, and if you have had a personal experience with a hurricane we would like to hear your story! How do hurricanes form?

 Floods occur when the ground, creeks, streams, and rivers can no longer absorb and hold the amount of water being produced by a rain event.  Buildings with basements, tunnels, or houses at low elevations are susceptible to flooding.  This moving water erodes sediment and can uproot plants and trees, destroy roads and destroy buildings.  After the waters subside, all this sediment can deposit, leading to a reshaping of the area’s topography. Floods

Flooding

  Take a minute to discuss with a neighbor how to prepare for a flood.  We will take a couple of minutes to discuss, and if you have had a personal experience with flooding we would like to hear your story! Floods
