Peru: High temperatures are forecast across eastern regions through at least Nov. 8

Forecast models indicate that high temperatures will persist across much of eastern Peru through at least Nov. 8. The National Meteorology and Hydrology Service (SENAMHI) of Peru have issued a warning for high daytime temperatures across much of the eastern rainforest region Nov. 7-8. Temperatures of more than 37 C (99 F) are possible in central and southern parts of the affected area and above 36 C (97 F) in northern parts Nov. 7. Maximums over 37 C (99 F) are likely in central and northern areas and above 36 C (97 F) in southern areas Nov. 8.

SENMHI has issued orange high temperature warnings across Ucayali, much of Madre de Dios, and parts of southern Loreto, southeastern San Martin, eastern Huanuco, eastern Pasco, northeastern Junin, northern and far eastern Cusco, and northern Puno Nov. 7. Yellow warnings are in place for surrounding areas to the west of the orange warning area and much of central, eastern, and southern Loreto Nov. 7. Further orange warnings are in place for central, eastern, and southern Loreto, eastern San Martin, eastern Huanuco, northern Ucayali, and northeastern Pasco Nov. 8, as well as yellow warnings across 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.
