Morocco: Heatwave forecast to persist across much of the country through at least April 15 /update 1

Forecast models indicate that a heatwave will persist across much of Morocco through at least April 15. As of early April 12, the Moroccan Directorate General of Meteorology has issued orange (the middle level on a three-tier scale) heatwave warnings across southern and central Morocco. Yellow heatwave and wind warnings are in place over most of the rest of the country. Authorities will likely issue new alerts or update/rescind existing advisories as weather conditions change over the coming days. Temperatures of up to 42 C (108 F) are forecast. The high temperatures are forecast to persist through at least April 15.

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.
