The storm has yet to pass. The official death toll of Hurricane Maria, which roared across Puerto Rico in September, stands at 64. But this month it became clear that it’s much higher, and poverty mixed with rotting infrastructure means a second disaster is unfolding. At least half of the island remains without electricity, meaning sometimes fatal consequences for water purification, hospital care and communication. As officials finally begin to acknowledge other storm-linked deaths — estimates surpass 1,000 — Maria may become America’s deadliest natural disaster in living memory.
