The Santa Rosa storm is a recurring climatic phenomenon in the central and eastern region of Argentina, as well as in Uruguay, and usually occurs between late August and early September. This storm is produced by the interaction of a cold front, typical of the winter season, with a warm front that heralds spring. According to the National Meteorological Service, The probability of a severe storm developing around August 30 is high.although it is not always associated with heavy rainfall.

Popular belief links the storm with the feast of Santa Rosa de Limacelebrated on August 30. According to legendIsabel Flores de Oliva, Known as Santa Rosa, she is said to have unleashed a storm with her prayers to prevent the landing of Dutch pirates in Lima in 1615. Since then, any storm close to that date is associated with the saint.

A 2022 SMN study analyzed precipitation data from 1906 to 2021, concluding that in 65 of the 116 years analyzed, approximately 56%, storms occurred on the date associated with Santa Rosa, although not always with heavy rains. This phenomenon is explained by the changes in atmospheric circulation that occur towards the end of winter, when warm and humid air begins to enter from the north, creating conditions conducive to intense storms.

SMN specialists emphasized that although it is popularly believed that the Santa Rosa storm is more intense than others, there is no evidence that this is always true. (Illustrative Image Infobae)

“In regions such as Patagonia, storms are not common, so the frequency of Santa Rosa is very low, as in the Northwest of Argentina (NOA), where the season is marked by the dry season and clear, sunny days predominate,” said SMN.

Instead, In central and northeastern Argentina, it is common for storms to occur during this time of year.. This is because “since mid-August, The atmosphere begins to experience changes in its circulation due to the proximity of spring, which encourages the presence of warm air, higher humidity and favorable conditions for the formation of storms,” ​​they clarified.

However, experts stressed that although it is popularly believed that the Santa Rosa storm is more intense than others, there is no evidence that this is always true.
