Another weather warning

Today colder air of polar origin will meet the tropical air that has been dominating our weather in the Canary Islands for the past days. At the same time the low pressure system that has been in the west for over a week will start to move away to the NE and finally dissipate. The clash between the two air masses will set off scattered thunderstorms and heavy showers of relatively short duration and warnings have been issued for La Palma, La Gomera and Tenerife.
During tomorrow the weather should improve substantially at last.
