Saudi Arabia’s General Authority for Meteorology and Environmental Protection is forecasting a heatwave in some areas of the kingdom from Tuesday.
The organisation said temperatures in the Eastern Province and eastern parts of Riyadh could exceed 48 degrees celsius and dust may affect horizontal vision during the day from Tuesday until the beginning of next week.
Western and coastal areas near the holy city of Madinah are also expected to be affected on Tuesday and Wednesday.
Furthermore, thunderstorms are forecast in the highlands of Jazan, Asir, Baha and Makkah, extending to the southern parts of Madinah.
This could lead to rain, clouds, high winds and a drop in horizontal visibility due to dust, the weather authority warned.
