Moore Tornado 2013

Yesterday a massive EF 5 tornado, struck Moore, Oklahoma and left behind major destruction. Reports are that the tornado reached a length of 1.3 miles wide at it's peak. The death is at 24, though that number is expected to rise and there are reports there are nearly 240  who are injured. Close to 100 have been pulled from the rubble, alive. This is not the first time, Moore has been struck by a tornado. There have been five in the past 15 years. Three, including yesterday's storm, have been of great magnitude. The first one was an EF 5 tornado on May 3, 1999, the other was back on May 8, 2003. That tornado was an EF 4.

This image from the National Weather Service in Norman, Oklahoma shows the path of the May 20, 2013 tornado, with that of the May 3, 1999 tornado. That path is almost identical.


 At the time, the 1999 was the most costliest tornadoes in the United States to date and the death toll from that tornado was 36. In 2011 it was surpassed by the tornado in Joplin, Missouri. The wind speed of the 1999 tornado was 302 mph, and was the highest wind speed ever measured in a tornado. Yesterday's storm had winds of over 200. 

Here's the satellite image showing the rotation of the systems, as they passed over the region:


There are also reports that residents had a 30 to 40 minute warning before the tornado hit. According to CNN, "As Gov. Mary Fallin had said Monday night, Lt. Gov. Todd Lamb said he believed residents had time to prepare for the storm. 'My understanding is that the warning system was good. It was adequate,' he said."

Below is a picture of some of the destruction caused by the tornado:


 Here's an aerial photo of the path:


In looking at the destruction, many homes where completely leveled from the winds. Schools and the town's only hospital were also in the direct path of the storm. Of the 24 reported killed, 9 were children.Oklahoma is known to be tornado prone, however tornadoes can occur anywhere. May is also a very active month for tornadoes. I wrote about tornado safety back in 2011 in this blog entry and in the wake of this tornado it is important to know the difference between tornado watches and warnings, as well as tips on how to stay safe.
