In the Jordan Valley, a small patch of map glows orange. It is a heat warning, issued by Israel’s meteorological service, signalling that on Tuesday the air will feel heavier than the thermometer alone suggests. The same bulletin paints yellow alerts across the Beit She’an Valley, the shores of the Dead Sea, and the Arava, while Jerusalem expects a mild 28°C and Tel Aviv a balmy 28°C under partly cloudy skies. This colour-coded language—yellow for caution, orange for more severe heat stress—is a daily vernacular across the region, a way of translating the invisible weight of humidity and sun into something legible.

Further west, in Algeria, the warnings are also chromatic but speak of different elements. A yellow-level alert from the national weather office covers a string of wilayas—Tébessa, Khenchela, Constantine, Sétif, Batna—where rain and thunder are expected on Tuesday. By Wednesday, the thunder will rumble across an even wider arc, from Jijel on the Mediterranean coast to Tindouf deep in the Sahara. The forecast reads like a roll call of ancient cities and desert outposts, each name a node in a network of anticipation. In Tipaza and Saïda, a heatwave adds another layer to the mosaic.

In Iran, the narrative is one of intensification. A meteorologist, Mohammad Asghari, tells state-linked media that Wednesday will bring a mid-level wave crossing the northern tier, delivering cloudbursts, lightning, and wind to the Caspian shores and the southern slopes of the Alborz mountains. By Friday, a new system from the northwest will deepen the rains in West and East Azerbaijan, Ardabil, and parts of Gilan and Mazandaran. Meanwhile, in the east, the wind will keep stirring the dust over Zabol—a city that has long lived with the 120-day wind, a seasonal gale that scours the Sistan basin. The forecast warns of reduced air quality and visibility in the border provinces of Kermanshah, Ilam, and Khuzestan, where dust storms are a recurring public health challenge.

Across the Gulf, the UAE’s National Centre of Meteorology sketches a quieter picture: fair to partly cloudy skies, a chance of convective clouds over eastern areas that might spill rain inland by afternoon, and overnight humidity on the western coast that could condense into light fog. The sea will be slight in the Arabian Gulf, moderate in the Oman Sea, and the tides are listed with the precision of a train timetable. In Morocco, the heat persists. The spokesman for the meteorological directorate, Hussein Youabed, describes a landscape of unstable cumulus clouds over the Middle Atlas and northern High Atlas, bringing localised thunder showers and even hail. Temperatures in the eastern region and the desert interior will hover between 41 and 46°C, while the Atlantic and Mediterranean coasts wake to low clouds and misty drizzle. The heat will gradually retreat by midweek, but the thunder will linger over the mountains.

What emerges from these bulletins is not just a set of predictions but a collective ritual of naming the sky’s moods. Each country’s forecast is a small daily epic, mapping risk onto familiar geography. The orange patch in the Jordan Valley, the yellow thunder alerts over the Algerian highlands, the dust rising from Zabol, the fog creeping onto UAE beaches—all are fragments of a shared regional grammar, a way of bracing for a week that will be, in some places, merely warm, and in others, a test of endurance. By Sunday, Morocco’s temperatures will climb again, and the cycle of warnings will resume.
