Update 31st July 2013:
- River levels increase forcing evacuations
- Around 3,000 affected in North and South Atlantic Autonomous Regions
- 500 Hectares of crops damaged
Many have been forced to evacuate due to increased levels of the the Rio Grande, Siquia, Mico and Rama rivers.
Constant heavy rainfall that first began on 17th July in Nicaragua’s North and South Atlantic Autonomous Regions has led to floods damaging around 500 hectares of crops and affecting nearly 3,000 people.
These two regions make up Nicaragua’s Caribbean coastline. The R.A.A.N (Región Autónoma Atlántico Norte – North Atlantic Autonomous Region) capital, Bilwi (formerly Puerto Cabezas), and the R.A.A.S. (Región Autónoma Atlántico Sur – South Atlantic Autonomous Region) Bluefields are shown on the map below.
Original Report from 5th July 2013:
Heavy rainfall has caused flooding in areas of Nicaragua over the last few days, especially over the weekend of 30th June onwards. Two people have died in flooding so far – one in Managua and one in Estelí.
One of the worst affected regions was the Municipality Prinzapolka, in the Northern Autonomous Atlantic Region. Damage to crops, livestock and infrastructure has been reported. Damage assessments made by the mayor of Prinzapolka confirm that 1,668 families (about 9,768 people) were affected by floods. Over 1,500 hectares of argricultural land, especially corn fields, were damaged.
In the municipality of Matagalpa, 23 km north of Managua, 504 families were affected due to the flooding of their homes. In Managua and Masaya, in total 51 houses were damaged.
The heavy rainfall in Nicaragua is said to have been caused by tropical waves. Tropical waves are considered by the Nicaraguan Institute of Territorial Studies (INET) as one of the main phenomena that cause rainfall in the country.
According to Wikipedia:
Tropical waves are a type of atmospheric trough, an elongated area of relatively low air pressure, oriented north to south, which moves from east to west across the tropics causing areas of cloudiness and thunderstorms
