Algeria, Morocco: Heatwave forecast to persist over the region through at least July 12 /update 2

Forecast models indicate that high temperatures will persist across much of Algeria and Morocco through at least July 12. Temperatures of up to 47 C (117 F) are possible across parts of the region over the coming days.

As of July 8, Algeria's National Meteorological Office has issued orange (the middle level on a three-tier scale) heat warnings across Adrar, Ain Salah, and southern Timimoun provinces through July 10 and western Batna, Djelfa, and M'Sila provinces through July 11. Yellow heat warnings are in place for Bordj Badji Mokhtar, El Menia, and Ouargla provinces. The Moroccan Directorate General of Meteorology issued yellow heat warnings across eastern parts of the country July 8 and orange heat warnings across eastern regions July 9. Yellow heat warnings are in place for some central and southern regions July 9. Authorities will likely issue new alerts or update/rescind existing advisories as weather conditions change over the coming days.

The extended period of oppressive heat and dry conditions may produce ideal circumstances for wildfire growth throughout the region. 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.
