Peru: High temperatures are forecast across central, eastern, northeastern, and southern regions through at least Nov. 19

Forecast models indicate that high temperatures will persist across much of central, eastern, northeastern, and southern Peru through at least Nov. 19. The National Meteorology and Hydrology Service (SENAMHI) of Peru has issued a warning for high daytime temperatures across much of the eastern rainforest region and parts of the central mountain region Nov. 17-19. Temperatures of more than 37 C (99 F) are forecast in the southern rainforest region, above 36 C (97 F) in the central and northern rainforest region, and above 25 C (77 F) in southern parts of the western mountain region Nov. 17. These highs will rise slightly to above 38 C (100 F) across the rainforest region Nov. 18-19 and above 26 C (79 F) in southern parts of the western mountain region Nov. 18 and above 27 C (81 F) Nov. 19.

SENMHI has issued its highest red level warning over parts of eastern Huanuco and northwestern Ucayali regions Nov. 18, southern Arequipa, central Moquega, and central Tacna regions Nov. 18-19, and central and northern Arequipa Region Nov. 19. Orange and yellow warnings are in place across much of the rest of the affected area Nov. 17-19. 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.
