Uruguay: High temperatures forecast to persist across western and central regions through at least Feb. 9

Forecast models indicate that high temperatures will persist across western and central Uruguay through at least Feb. 9. Daytime temperatures of 36-41 C (97-106 F) are likely across the central and western parts of the country over the coming days, with minimum temperatures of 22-25 C (72-77 F). Temperatures may drop temporarily in areas where thunderstorms and rainfall develop. Officials could upgrade or expand the alerts as the heatwave develops over the coming days.

The extended period of oppressive heat and dry conditions may produce ideal circumstances for further wildfire growth throughout the affected areas. The high temperatures may result in increased energy and water demand and a heightened risk of heat-related illnesses, such as heat exhaustion and heat stroke. Heatwaves also pose a threat to vulnerable groups - such as the elderly, children, pregnant women, and those with respiratory illnesses - due to the increased possibility of heat stroke or heat exhaustion during prolonged exposure to high temperatures. These health risks could also extend to relatively healthy individuals during significant heatwave events. In addition to significantly impacting athletes and those who work outdoors, high temperatures can cause problems for people using mass transit. The lack of air conditioning and cramped vehicles during rush hour may lead to some passengers being hospitalized for dehydration.

Very high temperatures may warp rail tracks and force passenger and freight trains to operate at reduced speeds. Road surface damage is also possible, and overheated vehicles may worsen traffic problems in urban areas where congestion is already a problem. Commercial trucking disruptions might occur, as very high temperatures put more stress on vehicles, making tire blowouts more common. Major flight disruptions are unlikely at regional airports, but general aviation disruptions are possible, and some airfreight carriers could reduce cargo loads. High temperatures could lead to an increased demand for electricity, which might trigger localized brownouts or blackouts, exacerbating hazardous conditions when air conditioning is no longer possible.
