"Industrial production edged up 0.1 percent in May, the second consecutive month with little or no gain. Revisions to total industrial production in months before May were small. In May, manufacturing production rose 0.4 percent after having fallen 0.5 percent in April. The output of motor vehicles and parts has been held down in the past two months because of supply chain disruptions following the earthquake in Japan. Excluding motor vehicles and parts, manufacturing output advanced 0.6 percent in May and edged down 0.1 percent in April; the decrease in April in part reflected production lost because of tornadoes in the South at the end of the month."
