As the nation watches the town of Moore, Okla., desperately search for survivors, meteorologists warn that the severe weather may not be over. Officials say that 9.5 million people—from Texas to Arkansas—remain under the threat of potentially catastrophic tornadoes. In an announcement Tuesday morning, Weather Channel meteorologist Kevin Roth delivered a warning to residents of central/east Texas and central Arkansas, where the storm is heading. “Another day of large and devastating tornadoes is possible,” he said. By Tuesday morning, thunderstorms were already wreaking havoc in Arkansas, with winds up to 60 miles per hour.
