Bolivia: High temperatures forecast across eastern and northern regions through at least Oct. 8

Forecast models indicate that high temperatures will persist across much of eastern and northern Bolivia through at least Oct. 8. 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 and Pando, much of Santa Cruz, and parts of eastern Chuquisaca, northern La Paz, and central and eastern Tarija departments. Maximum temperatures of 36-41 C (97-106 F) are expected in the affected regions Oct. 5-8. Authorities could possibly update or extend the coverage of weather alerts over the coming days. The government of Bolivia declared a national emergency in early Sept. amid a record-breaking wildfire season, and the period of excessive heat will likely exacerbate the wildfire situation.

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.
