This one is going to be a major challenge, no doubt there, but it's not going to be anything new for these facilities. The intensity of the storm may be worse, but these zoos and aquariums should be more than alright (actually, Zoo Miami keepers are quite sure of it and they may be in one of the worst spots!). They have faced hurricanes for decades and have finely tuned their procedures in response to what works and what doesn't. With reinforced buildings and all necessary medical and nutritional needs on location, there really isn't much need for any sort of evacuation. The system in place may not seem ideal but it largely works; the animals do make it through the storm healthy and not too stressed out. Zoos affected by hurricane Harvey are already beginning to look towards recovery and have done a fairly remarkable job seeing their animals through the flooding.
