Severe rainfall decrease in the Caribbean and Northern Zone
The National Meteorological Institute informed the country - mid-2018 - about the impact that the El Niño phenomenon would have, especially from December. This as a preventive action so that all public and private entities, as well as the productive sector, could take the required measures.
Currently, this phenomenon is already officialized internationally, and the oceanic-atmospheric models continue to forecast that it will be maintained, at least, during the first half of the current year, so that its effects will persist during this period. Currently there is a meteorological drought on the Caribbean slope.
Climatic anomalies in the country.
Since last November, very significant climatic anomalies are observed in our region and particularly in the country. Rain analyzes show a very dry pattern throughout the national territory but with greater impact in the Caribbean Region and the North Zone, since these months are usually rainy in these regions.
In December 2018 and January 2019, the percentages of rain with respect to the normal were less than 55% nationwide. December 2018 was the driest of that year in the Caribbean Slope, which reflects a strong anomaly, since March and September are the least rainy.
According to data from meteorological stations in the North and South Caribbean, the rain deficit in January of this year ranged between 60% and 75%. Also in Limón only 58 mm of rain was reported, being the second drier January of all the record. The last time in this situation was presented -for that month- was in another year of El Niño: 2002; in fact, of the five driest dunes, four corresponded to a year in which this event was present.
At the same time, higher maximum temperatures than normal and lower minimums have been recorded, reflecting the presence of the phenomenon and the dryness of the environment.
Due to the fact that this El Niño event will continue at least until June of this year, it is estimated that the irregularity of the rains will continue, maintaining a deficit scenario.
The IMN will continue to monitor this phenomenon at the national level to issue meteorological warnings to update the information.
