Tropical Storm Sara now threatens to wreak havoc over Central America with days of heavy rain, flooding and mudslides. Where is it going next?

Lots of factors in play but Tropical Storm Sara is expected to form this week and could become a major hurricane threatening the US next week.

A newly formed depression in the Caribbean could enter the Gulf of Mexico as Tropical Sara next week, potentially reducing the chances it could pose a threat to Florida later in the week.
