Tropical Storm Iota was brewing in the Caribbean Sea early Saturday, threatening a second tropical strike for Nicaragua and Honduras, countries recently ransacked by a Category 4 Hurricane Eta. The National Hurricane Center in Miami said Iota could bring dangerous wind, storm surge and as much as 30 inches (76 centimeters) of rainfall to the two Central American countries, approaching their coasts as early as Monday. There were no coastal warnings or watches in effect as of Saturday morning.
