The cold wave arrived with very low temperatures, and the National Meteorological Service (SMN) issued a “purple warning”, which affects several provinces, including Tucumán.
What many are wondering is what is the “purple warning”? According to the SNM, it is launched with the aim of advising and warning the population about a phenomenon that is occurring, in this case low temperatures, which can present inconveniences or difficulties in the normal development of social life.
For example, they can reduce visibility, such as fog, dust, smoke, or volcanic ash; and be territorially generalized and last for several days. It does not constitute a meteorological alert, since in the latter case it is taken as a reference to rains, storms, snowfalls or strong winds, which imply a high risk.
Faced with signs of unfavorable weather, the official body recommends visiting the “early warning” section of the website of the National Meteorological Service, where the information for the entire country is permanently updated.
