Tropical Storm Iota has strengthened into a Category 4 hurricane and is expected to make landfall tonight on the coasts of Nicaragua and Honduras, as much of Central America is still reeling from the devastation left by Hurricane Eta, which displaced at least 210,000 people. Meanwhile, Storm Vamco, downgraded from a typhoon, battered Vietnam Sunday after leaving 67 people dead in the Philippines as the country’s deadliest storm this year.
