@tornado_outbreak2 on Instagram: "Terrifying footage of the Moore, Oklahoma F5 tornado on May 3, 1999. This tornado had the strongest winds ever recorded at 302 mph. This tornado prompted the first ever Tornado Emergency. Sadly, 36 people were killed. No one knew 14 years later another devastating EF5 would strike Moore. Moore is the only place in the U.S. where an F5 & an EF5 crossed paths 14 years apart. Video from Newschannel4 (Mike Morgan). All rights go to them. #oklahoma #okwx #tornadowarn

Update: Tornado watch in effect for eastern Oklahoma
