Yes, Kilimanjaro Safaris at Disney's Animal Kingdom continues to operate during typical Florida rain showers. In fact, many frequent visitors and Cast Members consider the rain to be one of the best times to ride; many of the animals, such as elephants, rhinos, and giraffes, become more active and "frolic" in the cooler, wet weather. The safari vehicles are covered to keep guests mostly dry, though wind-blown rain can still reach the edges of the seats. The attraction only closes if there is lightning in the immediate area or if extreme weather (like a tropical storm) creates unsafe driving conditions for the trucks or visibility issues. If the rain is heavy, some animals may seek shelter, but others, like the lions, are famously more likely to be seen standing up and alert rather than sleeping.
