'Nocturnal monster': After days of killer tornadoes and storms, more is on the way: Updates

A tornado watch was issued by the National Weather Service Monday afternoon for parts of seven states in the central U.S., from Nebraska south to Texas. This means conditions are ripe for tornadoes to form. Tornado warnings were being issued in Oklahoma as of mid-afternoon.

At least 28 people have died and dozens more were injured in the wave of tornadoes and angry storms that roared across much of the Midwest and East from late Thursday through Sunday. AccuWeather said more than 80 tornadoes had been confirmed as of Monday morning, with areas of Kentucky, Kansas, Missouri, Indiana, Illinois and Virginia − where two deaths were reported − staggered by some of the worst damage.
