Hurricane Iota – A Major Disaster for Central America

A catastrophic disaster could be unfolding for Nicaragua and Honduras, in the same regions that were pummeled by Hurricane Eta barely two weeks ago. Hurricane Iota appears to be on its way to becoming a rare November Category 5 storm, and is looking very impressive on satellite images this morning. The torrential rain this storm brings could result in landslides, and inland flooding, exacerbated by soil that’s still quite damp from Eta’s onslaught. With recovery efforts ongoing, and people still without permanent shelter, Iota could be a major, life-threatening storm for this area.
