Event Reporting:

The Flood Observatory maintains a Global Active Archive of large flood events, 1985 to present. It is available to the public in both spreadsheet and GIS formats (both formats together provide the complete Archive). New events are entered into this archive each week. As of the end of 2015, there were 4319 events; each has a unique archive number.

Event Mapping:

In some cases, severe or damaging floods become the focus of Observatory inundation mapping. As part of collaborations with other organizations, and the Global Flood Partnership, the Observatory's maps and other data are made available to the public.

This event is selected for Observatory production of map and GIS data products.This web page and associated image and map (GIS) files are the permanent Flood Observatory record of this event.

This Event:

This Flood List link provides a summary. According to Flood List: "Over the last week Hurricane Otto storm has affected parts of Panama, Nicaragua and Costa Rica, causing at least 13 deaths and forcing thousands from their homes. Otto is the southernmost hurricane to hit Central America and one of the few to crossover from the Atlantic Ocean to the Pacific Ocean. Otto made landfall as a Category 2 hurricane on the Caribbean coasts of northern Costa Rica and southern Nicaragua in the afternoon of 24 November 2016, causing significant damage. Nine people have died as a result of the storm in Costa Rica and at least 4 in Panama. Hurricane Otto formed as a Tropical Depression on Monday 21 November 2016 east of San Andr├ęs Islands in the Caribbean Sea. After causing serious damage in Panama, Otto reached the coasts of Nicaragua and Costa Rica with sustained winds up to 175 km/h, making landfall near the city of San Juan de Nicaragua. Otto left at least 4 people dead in Panama, with some reports claiming the death toll to be as high as 8. According to the National Hurricane Center (NHC), Hurricane Otto is the southernmost hurricane to hit Central America. Otto was the first tropical cyclone to cross through Costa Rica since records began in 1851. The storm dropped an impressive amount of rain in the northern provinces of Costa Rica. According to the National Weather Institute of Costa Rica (Istituto Meteorol├│gico Nacional, IMN) rain up to 120 mm in 3 hours was recorded on the 24 November 2016 in several stations in Guanacaste and Alajuela "
