Cold currents that caused the low temperatures moved
Ecuadornerws:

The entry of cold air masses from the South Pacific caused the low temperatures that have characterized the inter-Andean region in recent days.
Javier Macas, technician of the National Institute of Meteorology and Hydrology (Inamhi), explained that the absence of clouds in the Sierra caused much more cold, especially at dawn; that is, a decrease in thermal sensation.
During the morning there was sun with normal temperatures. For example, the Austro with stood temperatures of up to 25 degrees during the morning, but at night there were winds of 15 kilometers per hour. The entity indicated that the accumulation of energy caused the formation of a phenomenon of hot and humidair columns, which led to the formation and fall of hail.
For this reason, strong hailstorms were recorded during the afternoon of Tuesday in the Cajas National Park, in the west of Cuenca, and four days before, in Azogues (Cañar). Something similar has been experienced in the Sierra Center,where the rains have been intense.
In Tungurahua, rainfall caused landslides in the Ambato-Guaranda road and the fallof a retaining wall in Ambato. In Chimborazo, several streets were flooded in the Guano and Riobamba cantons.
In this last city, water clogged sewers and flooded several downtown streets.”This mass has already moved and temperatures are returning to their normal ranges,” said Macas. Therefore, he added, conditions could change for the next 48 hours due to the entry of moisture from the Amazon, which would cause afternoons and nights with rains, during the winter season.
El Niño that would reach the coasts would be light International organizations predicted an 80% probability of developing an El Niño event in the central Pacific. However, its impact would be weak.
In Ecuador, the National Committee for the Regional Study of the El Niño Phenomenon (Erfen) remains alert. The group brings together climate monitoring institutions and issued its statement on Tuesday.
“The consequences or impacts in the Ecuadorian sea have not yet manifested; However,it is expected that if this hot event occurs, both the temperature and the sea level, will register positive anomalies (above normal), sustained in thefollowing months “.
The sea surface temperature has remained within normal parameters, without exceeding 26 ° C. The Erfen concluded that the rains in December will be between the normal ranges. For the Litoral conditions were predicted below normal, with the exception of the north where there will be no variations.
In the Coast, the month of the transition between the dry and the rainy season is already lived. (I)
