Europe to Experience Widespread Rainfall

High temperatures continue to persist from southern Spain to southern Portugal

It is forecasted that over the next three days, Europe will be influenced by a low-pressure vortex (Figure 1), leading to widespread light to moderate rainfall across most regions. In particular, parts of eastern Northern Europe, eastern Central Europe, western Eastern Europe, and northern Balkan Peninsula are expected to experience moderate to heavy rain, with localized downpours. These areas will also be accompanied by severe convective weather such as short-duration intense rainfall and thunderstorms with strong winds. The cumulative rainfall in these regions is generally expected to be between 5 and 25 mm, with some areas receiving 40 to 80 mm, and locally exceeding 120 mm (Figure 2). Attention should be given to the potential for localized heavy rainfall to trigger secondary disasters such as flooding in small and medium-sized rivers and urban waterlogging.

Affected by rainfall, high temperatures in most of Southern Europe have eased. However, persistent high temperatures continue in the region from southern Spain to southern Portugal, with daily maximum temperatures generally ranging between 35°C and 37°C, and locally exceeding 39°C (Figure 3).
