Bolivia: High temperatures forecast across central, eastern, and northern regions through at least Sept. 26

Event

Forecast models indicate that high temperatures will persist across much of central, eastern, and northern Bolivia through at least Sept. 26. The National Meteorology and Hydrology Service (SENAMHI) of Bolivia has issued an orange warning (the middle level on a three-tier scale) for rising temperatures across Beni, Pando, and Santa Cruz departments and parts of eastern Chuquisaca, eastern and northeastern Cochabamba, northeastern La Paz, and central and eastern Tarija departments. Maximum temperatures of 36-41 C (97-106 F) are expected in the affected region, with highs of 39-45 C (102-113 F) possible in the Bolivian Chaco in the southeast of the country. Authorities have warned of the increased risk of wildfires breaking out across the country due to hot and dry conditions; the government of Santa Cruz Department has issued an orange forest fire risk alert across the department as of Sept. 25.

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.

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.
