A member of the media rushes from the motorcade in the pouring rain as President Barack Obama attends a campaign event, Tuesday, Sept. 18, 2012, in New York.

High winds and rain caused delays for commuters and air travelers as a storm moved through the region on Tuesday.

The weather also brought with the threat of a repeat of the two tornadoes that touched down in Brooklyn and Queens earlier this month.

The National Weather Service issued a tornado watch for the New York City metropolitan area, and later extended it to 9 p.m. in Manhattan, where the worst of the storm was expected to hit at 8 p.m.

There were no tornado reports, but forecasters predicted severe thunderstorms and winds topping out at 50 mph. A wind advisory will remain in effect until 6 a.m. Wednesday.

Study links chemical BPA to obesity in children, teens

Kids with higher levels of the widely used substance BPA in their bodies are more likely to be obese, according to the first large-scale, nationally representative study to link an environmental chemical with obesity in children and teens.

Researchers from NYU School of Medicine acknowledge that their study's design doesn't allow them to definitely conclude that BPA, or bisphenol A, caused the children's obesity. Rates of obesity have been rising for three decades as Americans have become more sedentary.

But the findings, in today's Journal of the American Medical Association, add to a growing body of research -- in both humans and animals -- questioning BPA's safety, says Philip Landrigan, director of Children's Environmental Health Center at the Mount Sinai School of Medicine in New York.
