Uruguay issues special alert for fog and mist, reducing visibility nationwide

Uruguay is experiencing unusual weather for early June, with fog and mist significantly reducing visibility across the nation. The Uruguayan Institute of Meteorology (Inumet) issued a special alert, warning that these conditions would persist until at least Saturday, June 6.

Inumet's forecast indicates a continuation of reduced visibility due to fog and mist. The weekend is expected to be damp with abundant cloud cover. Fog and mist are predicted to linger, potentially worsening towards the west by the afternoon and bringing a chance of storms. Sunday is expected to see a slight temperature drop with overcast skies, bringing more rain and possible storms, particularly north of the Río Negro.

Meteorologist José Serra described the situation as "totally atypical" for this time of year. He noted temperatures are higher than normal, with high humidity levels expected to last for several days. This is attributed to a strong high-pressure system over the Atlantic, drawing warm, humid air into Uruguay. This atmospheric setup is causing a "blocking situation," leading to what Serra calls a "pseudo summer" that will continue until at least Friday, keeping temperatures above average for early June. Relative humidity is expected to remain around 85% for consecutive days, fostering fog formation, especially during nights and early mornings. Serra also anticipates rain in the region between Monday and Tuesday of the following week.
