Meteorologist warns of 'totally atypical' atmospheric situation in Uruguay

Uruguay is facing a highly unusual atmospheric situation for early June, meteorologist José Serra warned. The country is experiencing temperatures above average and high humidity levels that are expected to persist for several days.

Uruguay is going through a totally atypical atmospheric situation for this time of year, marked by temperatures higher than normal and high relative humidity levels that will extend for several days.

Serra explained that this phenomenon is due to a powerful high-pressure system, an anticyclone, situated over the Atlantic Ocean. This system generates north and northeast winds, drawing warmer and more humid air into Uruguay. This atmospheric configuration, combined with systems in the mid and lower atmosphere, is creating a "semi-blocking" effect over the nation.

The "pseudo summer heat" that began recently is forecast to continue until at least Friday, keeping temperatures higher than typical for early June. Relative humidity will remain very high, around 85%, for consecutive days, likely leading to fog and mist, particularly during the nights and early mornings. Light rains are possible early next week.

This configuration is also associated with systems present in the middle and lower levels of the atmosphere, which causes a new atmospheric blocking situation over Uruguay.

Temperatures have already exceeded seasonal norms, with highs reaching 24°C in the north, 22°C in the west, and 19°C in Montevideo on Thursday. Serra noted that while such episodes can occur in autumn, the unusual aspect is the series of anomalous weather events observed since May. This included heavy rainfall in early May, an 11-day cold snap with sub-zero temperatures, and persistent fog.

This scenario will favor the formation of fogs and mists, especially during the nights and early morning hours.

"We are facing a new semi-atmospheric blocking situation, with several days of very high relative humidity. It is harmful to health and indicates something is wrong in the atmosphere," Serra stated, highlighting the persistent deviation from normal atmospheric behavior.
