A moist easterly wind may also push rainbands into areas facing the Mediterranean.

Conditions are mostly settled in the south and west including Andalucia, the Costa del Sol and much of Andalucia. There is plenty of sunshine, but no intense heat.

What it means for popular destinations

Once any remaining cloud has cleared, the Costa del Sol will enjoy a weekend with plenty of sunshine and pleasant temperatures. Costa Blanca, Murcia and the rest of Andalucia will have a mixed weekend. The weather is expected to be mostly sunny, but there’s a chance that storms will develop inland in the afternoon on Sunday.

Barcelona and the Catalan Coast are at higher risk for rain and thunder, especially later in the weekend. The towns in the north of France should be prepared for a changeable and cooler climate.

In recent weeks, it has been shown that storm cells can quickly form following heat waves. If you are planning to go outdoors or have travel plans booked, check your local warnings.
