Why scientists believe 'tornado alley' is shifting
Scientists at the National Weather Service are looking through the damage to figure out the scope of Mondays tornadoes that ripped through Central Texas.
Since Central Texas saw multiple tornadoes along a complicated and long trek of populated areas, scientists say it may take a couple of days to come up with a scale for these storms.
Tornadoes are deciphered using an Enhanced Fujita scale (EF Scale). The EF Scale was developed based on damage intensity which can range from an EF-0 to an EF-5.
EF-3 damage would include destruction to roofs and some walls torn from well-constructed houses; trains overturned; most trees in forested areas uprooted; heavy cars lifted and thrown.

What we saw yesterday afternoon was not common for this region, said Yura.
