Algeria: Heatwave forecast across northeastern, central, and southern regions through at least June 29

Forecast models indicate that a heatwave will persist across parts of northeastern, central, and southern Algeria through at least June 29. As of early June 27, the Algeria National Meteorological Office has issued orange (middle level on a three-tier scale) heatwave warnings across Adrar, In Salah, Bordj Badji Mokhtar, Ouargla, and Timimoun provinces; maximum temperatures of more than 49 C (120 F), with minimum temperatures of 34-38 C (93-100 F) are forecast through June 29. Orange heatwave warnings are also in place June 27-28 across El Oued, Touggourt, and El M'Ghair provinces where maximum temperatures of more than 49 C (120 F) with minimum temperatures of 32-36 C (90-97 F) are forecast as well as across Medea, Djelfa, M'Sila, Bouira, southern Bejaia, Mila, Constantine, Batna, Souk Ahras, Tebessa, and Khenchela provinces where maximum temperatures of 43-45 C (109-113 F) with minimum temperatures of 25-33 C (77-91 F) are forecast. Yellow heatwave warnings are in place across most of the rest of the affected area.

The extended period of very high temperatures and dry conditions may increase the potential for wildfires throughout the region and result in drought conditions in the country. Authorities may implement water rationing, restricting water supply when necessary; they may also prohibit the use of potable water to irrigate green spaces or limit water withdrawal from wells, springs, or waterways.

Heatwaves pose a health 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 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. Some passengers may require hospitalization for dehydration due to the lack of air conditioning and cramped vehicles during rush hour.

Overheated vehicles could prompt traffic disruptions in urban areas where congestion is already a problem. Commercial trucking disruptions might occur, as very high temperatures put more stress on vehicles and make 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.
