The Brazilian state of Rio Grande do Sul is facing significant heatwave concerns as temperatures are set to soar, with the Instituto Nacional de Meteorologia (INMET) having issued a red alert.
On February 5, INMET announced the warning, stating the state could experience temperatures up to 5°C above average through to February 10. This alarming forecast has put many regions, including the metropolitan area of Porto Alegre, the Vales, Campanha, and several others, on high alert.
Recent reports indicate the severity of this heatwave, with Quaraí recording the highest temperature ever logged in the state: 43.8°C. This historic peak was reached on February 4—the highest temperature recorded by INMET since its monitoring began over 115 years ago. Previously, the record was held at 42.9°C, observed in Uruguaiana on February 27, 2022.
The meteorological conditions across Brazil have been impacted by the active La Niña phenomenon, which continues to create intense heat episodes, particularly affecting southern regions. Predictions suggest temperatures could break the 40°C mark near the Uruguay and Argentina borders, as various local meteorologists, including Climatempo, point out the probability of these elevated temperatures extending across the region.
The forecast for February suggests Porto Alegre will likely see temperatures slightly above the normal range with lower-than-average rainfall expected, particularly along the border with Argentina.
The INMET’s warning highlights the low hydration and health risks involved due to the extreme heat, as residents are urged to remain vigilant. Recommendations from civil defense authorities include the importance of hydration, avoiding direct sun exposure during peak hours, and finding well-ventilated spaces to cool down.
The elaborate heat alert system from INMET includes classifications such as yellow (potential danger), orange (danger), and red (great danger). The current red alert signifies exceptionally high risks, advising the public to prepare for potential emergencies.
Looking at the weather forecast for the next several days, Porto Alegre is expected to experience fluctuated temperatures, including maximums of 36°C on February 5, followed by slightly lower readings of 35°C on the 6th, and decreasing even more to 29°C on the 7th before rising again to 34°C on the 8th, and back up to 38°C on the 9th.
Residents are advised to follow the guidelines set forth by authorities, which include wearing light clothing, using sunscreen, and taking care of vulnerable populations such as children and the elderly.
The urgency of the situation cannot be understated, as such extreme temperatures pose not only discomfort but severe health risks if precautions are not taken seriously. Public engagement and adherence to safety recommendations will be pivotal as this heatwave progresses.
With February promising to remain unforgivingly hot, residents of Rio Grande do Sul need to stay informed and proactive. The impact of climate conditions continues to be felt, reminding us all of the importance of preparedness during extreme weather events.
