Un poco mas de agua

We can expect the stormy weather here to continue until next Tuesday. In the meantime much of Spain is still enjoying warm sunshine but that is not forecast to last.

Normally we could expect a "gota fria" in Autumn which would start in the Gulf of Cadiz and move rapidly towards Catalonia and the Balearics. This is an altogether different weather system. It is a band of slow moving cold air which is coming from the East of Europe that is causing instability. As the cold air -high in the atmosphere - meets the warm air which is rising from the sea it becomes unstable and creates storm conditions. The effect is similar to a gota fria but slower moving and hence longer lasting.

The last time the area had weather like this was in September 1986 when Alcoy suffered serious floods and storms which deposited 300 litres of water per square metre. The 144 litres per square metre of rain that hit Sueca (Valencia) yesterday was the highest registered in the Valencian Community for 20 years.
