1999 Bridge Creek–Moore tornado
1999 tornado in Oklahoma, US
(Redirected from 1999 Bridge Creek-Moore tornado)
The 1999 Bridge Creek-Moore tornado was a very violent F5 tornado that hit the Bridge Creek and Moore areas of Oklahoma on the evening of May 3, 1999. It had the highest wind speed ever recorded at 301 miles per hour (484 km/h).[6] It killed at least 36 people and injured 583 others.[5] It caused $1 billion in damage.[7] The tornado's strength led to the National Weather Service Weather Forecast Office in Norman issuing the first-ever tornado emergency.[8] In 2013, Moore was again hit by an EF5 tornado, but fewer people were killed even though there was more damage.

Notes
change- ↑ It is officially accepted that the rating for this tornado is F5; however, the ±20 mph (32 km/h) wind speed ambiguity has occasionally led some people to suggest that this tornado may have briefly been an F6 tornado. On the original Fujita Scale, F6 was a theoretical classification for an "inconceivable tornado", with a wind speed in excess of 318 mph (512 km/h), but no tornado ever produced winds officially at or above 319 mph (513 km/h). The United States National Weather Service has officially maintained that the Bridge Creek–Moore tornado is an F5 tornado, and will not be reclassified F6.[2]
