On Tuesday, a winter storm brought snowfall to parts of the American South, as animals in a Houston, Texas zoo embraced the sudden weather shift. An Asian elephant is excited to experience the winter snow as it runs through the zoo, and a North American river otter slips and slides through icy terrain. Other animals, like sea lions, frolic in temperature-controlled water while snow continues to fall around their surroundings. The rare frigid storm has charged through Texas and the northern Gulf Coast, blanketing New Orleans and Houston with snow that closed highways, grounded nearly all flights and canceled school for more than a million students more accustomed to hurricane dismissals than snow days.
