Powerful storms packing high winds, torrential rain and hail slammed heavily populated parts of the U.S. Northeast, snarling transport and causing widespread power outages in an area home to tens of millions of people. The National Weather Service issued a severe thunderstorm warning from Maryland to New Hampshire. There were nearly 50 reports of hail in states including Ohio, Pennsylvania, New York and Connecticut. A tornado was spotted in Sullivan, in northern New York, but there were no reports of damage. Parts of Connecticut were placed under a tornado warning.
