[UPDATED] Rain, high winds, hail stun East Coast STATE COLLEGE, Pa., June 13 (UPI) -- High winds and hail as big as ping-pong balls tore up the eastern U.S. coast Thursday, toppling trees and halting the U.S. Open, officials say. A 57-mph wind gust was recorded mid-morning in Woodbury, N.J., while emergency managers in Frederick County, Md., reported multiple incidents of downed trees, Accuweather.com reported. The system of massive thunderstorms and hailstorms with severely damaging winds spawned at least two tornadoes near Columbus, Ohio, late Wednesday night. No injuries were immediately reported. About 9:15 a.m., Webster County, W.Va., reported receiving more than 1.5 inches of rain in less than two hours. Earlier, the U.S. Open suspended play as storms approached Philadelphia. Elsewhere in Pennsylvania, three homes were reported to have sustained minor damage from a lightning strike. Minor road flooding was reported throughout the area. Hail ranging from quarter-size to that of ping-pong balls was reported in two counties in Maryland. The strong thunderstorms brought a high risk of flash flooding to West Virginia, Virginia, the District of Columbia, Maryland, Pennsylvania, New Jersey and New York through most of Thursday, with flooding also possible in North Carolina, South Carolina and northeast Georgia, the National Weather Service and AccuWeather said. The weather service had previously issued tornado and severe-thunderstorm warnings for other Ohio Valley counties and points east and southeast after the unusually massive line of storms plowed through eastern Iowa, northern Illinois and Indiana and southeast Michigan. Airlines canceled more than 150 flights at O'Hare International Airport in Chicago.
