Tornadoes wreak havoc in US
SOURCE : www.boston.com
Tornadoes can form anytime of year, but occur most frequently in April, May, and June, due to favorable weather conditions. Earlier this week a massive 200-mile-per-hour EF5 tornado hit Moore, Okla., killing some two dozen people, damaging thousands of structures, and causing an estimated $2 billion in damage. This year, twisters have already touched down in Kansas, Texas, Tennessee, Mississippi, Missouri, and Alabama.

This image released by the Nasa on May 21and acquired on May 20 by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASAǃÙs Aqua satellite shows the storm system at 2:40 p.m. Central Daylight Time (19:40 Universal Time), just minutes before the devastating twister began. According to National Weather Service and media reports, the mile-wide tornado had a preliminary damage rating of EF-4, with winds reaching 190 miles per hour. It had a relatively slow forward speed for such a violent stormǃÓabout 20ǃÏ25 miles per hourǃÓlikely exacerbating the damage. Debris from the tornado fell as far as 100 miles (160 kilometers) away, reaching the city of Tulsa. The massive tornado that cut a wide and deadly swath through a suburban Oklahoma City town, killing 24 people, was a top category EF5 system with winds over 200 mph (321 kmh). (NASA) #
