Midwest and north-east US brace for powerful storm and possible tornadoes

Storm system leaves thousands without power in Texas and Louisiana and is heading east toward New England

A relatively powerful storm system headed east on Friday threatened the midwest and north-east US with heavy snow after spawning likely tornadoes in Texas and Louisiana which damaged homes, businesses, a university campus and left thousands without power.

The Tennessee and Ohio valleys are bracing for high winds and potential tornadoes as the storms roll on toward New England, according to officials.
