Advertisement Washington: When snow began falling over Dallas last weekend Emilia Rodriguez Carrasco felt a rush of excitement. This was the first time she and her husband Daniel, who moved from Sydney to Texas in October, had ever seen real snow. âIt was a novelty for us,â Emilia, 28, said. âIt was great to go out and see snow on the street.â The novelty turned into a nightmare a few hours later when the power went down in the Carrascosâ apartment. They were among 4 million people in Texasleft without electricity after heavy snow and sub-zero temperatures caused the stateâs power grid to melt down.
