STORM SURGE: A dangerous storm surge will raise water levels by as
much as 9 to 13 feet above normal tide levels in areas of onshore
winds along the coast of Nicaragua and Honduras. Near the coast,
the surge will be accompanied by large and destructive waves.
SURF: Swells generated by Iota will affect portions of the coast of
Colombia, and the southern coasts of Hispaniola and Jamaica during
the next day or two. Swells will begin to reach the coasts of
