Peru: High temperatures are forecast across much of the interior of the country through at least Dec. 3

Forecast models indicate that high temperatures will persist across parts of the interior Peru through at least Dec. 3. The National Meteorology and Hydrology Service (SENAMHI) of Peru has issued a warning for high daytime temperatures across much of the central mountain region through Dec. 2, with highs of up to 30 C (86 F) forecast in the region. Another warning for high daytime temperatures is in place for parts of the eastern rainforest region through Dec. 2 and a separate warning has been issued for central and northern parts of the rainforest region Dec. 3; highs of up to 38 C (100 C) are forecast in northern parts of the region Dec. 2 and up to 36 C (97 F) in central and southern parts Dec. 2 and central and northern parts Dec. 3. SENMHI has issued its highest red level warning over parts of southern Loreto, eastern San Martin, central, eastern, and northern Ucayali, far eastern Huanuco, and northern Madre de Dio regions Dec. 2. Orange and yellow warnings are in place across much of the rest of the affected area. Officials could update and possibly extend the coverage of weather alerts over the coming days.

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.

The extended period of oppressive heat and dry conditions may produce ideal circumstances for wildfire growth throughout the affected areas. 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.
