Two storm systems explained New DANA rain forecast

Oct 5

In the complete weather presentation, Mónica López distinguishes the Mediterranean convective storms since Thursday from a separate western DANA. She explains that warm sea water helped organize rotating storm systems, including Monday's heavy rain in Granollers, giving them the appearance of tropical cyclones; she does not confirm a named medicane. The latest system is moving east and remains under observation. She then describes cold upper-level air over western Spain and forecasts storms as that DANA advances east on Tuesday, orange warnings in northern areas, rain patterns and temperature changes, including later cold nights. These forecasts are kept separate from observed flooding and from the earlier Mediterranean system.

A new torrential-rain episode floods Granollers on October 5, trapping drivers and disrupting transport. RTVE reports cumulative rainfall of more than 300 litres per square metre since Saturday and broader Catalan damage assessments and cleanup, including flooded homes, health facilities, schools and a hotel evacuation. The aid announcement is a response within the complete report, while its weekend casualties and cumulative damage are not all assigned to Monday. Mónica López explains the Monday storm as the latest rotating, warm-sea-driven convective system, with a tropical appearance rather than a confirmed named medicane.
