Waiting the Sudestada

Sudestada (literally Southeast hit) is the Spanish name for a climatic phenomenon common to the Rio de la Plata and its surrounding region consisting of a sudden rotation of cold southern winds to the south-east. This change, whilst moderates the cold tempetures, lads the air masses with oceanic humidity, bringing heavy rain and rough seas in the coastal regions. The air circulation also increases the intensity of the winds. The Sudestada is most likely to happen in late fall and winter.
