The Big Apple was hit with severe weather on Wednesday, with Hurricane Arthur making its way up the East Coast [1] and its effects reaching New York. Thunderstorm watches and warnings were issued in NYC, with a huge downpour hitting the city as lightning lit up the skyline. Thousands of people were left without power throughout the state, and flash-flood warnings have been in effect. The severe weather comes just days after a derecho storm hit the Great Lakes area [2], where Chicago saw its fair share of lightning, too. Take a look at some of the most unbelievable photos from NYC's big storm.
