Worse to come
El Niño-Southern Oscillation (ENSO) phenomenon that causes drought and very hot conditions is just beginning and could be with us for the next nine months, with increasing intensity through the first half of the year.
The population must prepare to face water rationing and even problems in the electricity supply.
There is concern among the experts because even in the North and Atlantic Zone it does not rain when it is normal for this season to have rainfall.
El Niño is associated with a band of warm ocean water that develops in the central and east-central equatorial Pacific.
There is no consensus on if climate change will have any influence on the occurrence, strength or duration of El Niño events. Each country has a different threshold for what constitutes an El Niño event.
Historically, El Niño events are thought to have been occurring for thousands of years.
La Niña typically has the opposite effect in Costa Rica increasing rainfall slightly on the Pacific side and sometimes drying out the Caribbean.
