NEW ORLEANS - Officials at the Storm Prediction Center in Norman, Oklahoma, say the 12 tornadoes on Tuesday that hit Louisiana set a record for the most in a day in February.

Meteorologist Greg Carbin says the new state record more than doubled the old record of six in 2008. Carbin says the National Weather Service has maintained more reliable records on tornadoes since 1950.

The most powerful tornado hit the Sugar Hill RV Park in Convent, where two men were killed. One was from Alabama and the other from North Carolina. St. James Parish officials say up to 30 were injured, some critically.

On Thursday, the weather service upgraded the ranking of the RV park tornado from EF-2 to EF-3 with winds up to 140 mph.
