Very high temperatures are forecast for mainland Portugal during the weekend and the beginning of next week. On Sunday and Monday, Alentejo is expected to reach 40°C, while Lisbon could reach 37°C. This heat wave will affect much of the national territory.

According to forecasts, between this Friday and the beginning of next week, only the cities of Viana do Castelo and Aveiro should not record maximum temperatures above 30°C. The remaining regions of the country will face intense heat.

The article also mentions that the downburst that occurred in Aveiro was not the first of the year, suggesting the occurrence of previous extreme weather phenomena in the same region. This information indicates a trend toward severe climatic events in the area.

Curiously, the text includes a reference to clouds with 10 sides on Saturn, apparently being a science note or curiosity included in the same opinion article or section.
