Bolivia, Peru: High temperatures are forecast across parts of the region through at least Aug. 26

Event

Forecast models indicate that high temperatures will persist across much of eastern Bolivia and central and eastern Peru through at least Aug. 26. The National Meteorology and Hydrology Service (SENAMHI) of Bolivia has issued an orange warning (the middle level on a three-tier scale) for high temperatures across parts of eastern Beni, eastern Pando, and central and eastern Santa Cruz departments. Maximum temperatures of 36-41 C (97-106 F) are expected in the affected regions through at least Aug. 25. The National Meteorology and Hydrology Service (SENAMHI) of Peru has issued orange and yellow high-temperature warnings across much of the eastern rainforest region through Aug. 25 and central and southern parts of the central mountain region through Aug. 26. Temperatures of more than 38 C (100 F) are possible in eastern areas and up to 30 C (86 F) in mountainous 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.

Hazardous Conditions
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.

Transport and Utilities
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.

Advice

Monitor local media for weather updates and related advisories. During heatwaves, remain indoors in air conditioning when possible. If outdoor activities are necessary, frequently rest in shaded areas; avoid activity during the hottest times of the day. Stay well-hydrated by drinking plenty of fluids. Avoid alcoholic beverages, which are dehydrating; drink water that is bottled or has been boiled. Wear loose-fitting, light-colored clothing. Cotton fabrics are more cooling than synthetics. Promptly seek medical attention if signs of heat exhaustion or heat stroke develop. Charge battery-powered devices in case prolonged electricity outages occur.
