Meteorology

Main article: Climate of Colombia

Colombia is a country located in the Intertropical Convergence Zone and as an effect to this, the country is vulnerable to the meteorological patterns that affect the Caribbean region such as hurricanes and tropical storms. Remnants of Hurricane Tomas in combination with La Niña made the 2010 wet season of Colombia one of the deadliest and heaviest in rainfalls in the last 40 years. The torrential rainfall, wind gusts, electric storms and a constant light rain in some places started in June 2010 and became stronger and more frequent in August and September.

Impact

The floods and landslides affected 70% of the country and left homeless more than 2,2 million people. 301 people have been killed

Guajira Department

The Colombian System of Information for the Prevention and Attention to Disaster CREPAD (Sistema de informacion para la Prevencion y Atencion de Desatres) established that throughout 2010 there were 10.303 people affected by the rains with a total of 1.819 families and 9 homes completely destroyed and 334 in very bad conditions.

The department of Guajira being located in the northern tip of Colombia was seriously affected by the 2010 hurricane season. Remnants of the tropical storm Matthew hit Guajira and the Atlantic coast of Colombia with heavy rains. Among the most affected municipalities are Maicao, Riohacha and Manaure. Maicao and Riohacha have been the most affected ones since a number of families live in homes usually located in lower grounds. This communities are usually the most vulnerable because many of them are organized without the control of the Office for the distribution of land that regulates the housing building in Colombia.

Atlántico Department

The department of Atlántico has been particularly affected by the rupture of the levees of the Dique Channel (Canal del Dique). To the south of the Department of Atlántico some tributaries of the Magdalena river crested and flooded entire towns. This flood was able to raise the levels of the El Guajaro dam to a flow of 1400 cubic meters per second.

According to Semana magazine the emergency has been compared to the floods caused by Hurricane Katrina in New Orleans, United States. The magazine also predicted that is possible that many of the inhabitants of southern Atlántico might never be able to come back to their lands and will have to change their way of life due to the impact of the floods.

Bolívar Department

Bolívar Department is also one of the most affected areas of the Colombia rainy season of 2010. In December 2010 the Minister of Defense Rodrigo Rivera Salazar traveled to the city of Cartagena (capital of Bolivar) in order to evaluate and coordinate the steps to take to diminish the emergency faced by the department. The minister informed that Bolivar had 60 thousand affected households and called it "the department most seriously hit" by the rainy season and its floods.

Cundinamarca Department and Bogotá
