Barcelona on alert for heavy rain this Tuesday: up to 40 litres could fall in half an hour

The rain still hasn’t let up. The Servei Meteorològic de Catalunya (Meteocat) has issued a new round of warnings as storms, which could be very intense in some areas, are expected from this Tuesday and at least through Thursday.

The most critical period is expected on Tuesday afternoon, when much of the Catalan coast and pre-coastal areas will be under an orange alert.

Barcelona among the areas under orange alert

The warnings cover the coast from Empordà to Terres de l’Ebre, including Barcelona and Baix Llobregat, as well as various inland and western regions.

The storms could bring up to 40 litres of rain per square metre in just 30 minutes.

The associated danger level reaches 4 out of 6, so extra caution is advised during the most unstable hours.

There is also a particular concern: rain will fall on areas that have already received a lot of water in recent episodes, so some land and flood-prone spots may already be saturated.

Warnings will continue until Thursday

The episode will not end on Tuesday. Rainfall intensity warnings remain in place, at different levels and in different areas, at least until Thursday afternoon.

On Tuesday morning, the southern third of Catalunya remains under a yellow alert. On Wednesday, yellow alerts will affect various points along the coast and pre-coastal areas.

For Thursday, in addition to rain alerts, Meteocat has issued warnings for wind and rough seas.

Several more days of unsettled weather

Aemet also forecasts that the period of atmospheric instability, rain, and storm risk will continue over the coming days and last at least until Thursday.

The evolution of these episodes can change quickly, so authorities recommend following weather updates and paying special attention to flood-prone areas.

After several days of heavy rain and mobility issues in Catalunya, this Tuesday it’s time to keep an eye on the sky again, especially in the afternoon.
