Flooding from weeks of torrential rain in northern South Africa led Kruger National Park to suspend visits and evacuate some guests and staff members by helicopter. The national parks agency closed several of Kruger’s nine entrances and barred day visitors until conditions improve. At least 19 people died in Mpumalanga and Limpopo provinces since the rains began last month, according to the National Disaster Management Center. The South African Weather Service issued a red-level 10 alert for parts of the northern region and forecast 100 to 200 millimeters of rain over the next two days.
