Local Weather History For May 20th...
|
|
An otherwise beautiful mid-May afternoon gave way to another
devastating tornado to the cities of Newcastle and Moore on this day in 2013. This tornado came one day after tornadoes ravaged other portions of central Oklahoma. A supercell storm developed over the northern portions of Newcastle and quickly became tornadic. This storm produced damage on the north side of Newcastle, then intensified and moved eastward through the city of Moore. The tornado reached EF5 strength, destroying two occupied elementary schools and damaging or destroying more than 1500 homes and businesses. Twenty-four people lost their lives and more than 300 were injured. Property losses approaching $1.5 billion have been estimated for this tornado, making it the costliest tornado in Oklahoma history, surpassing the May 3, 1999 storm. |
