If you were cooking, you'd have the right ingredients for the recipe to serve up a tasty dish. Over the next couple of days we'll have all the right ingredients for cooking up a storm. We can expect outbreaks of heavy rain together with thunder and lightning at times.

Low pressure has been developing over the Bay of Biscay and western France. Thats going to track northwards - the West Country is in its path.

This weather system is going to drag in warm air from the continent - making it feel very humid. And its a potent cocktail for much heavier rain and electrical storms. Warmer air carries more moisture - hence the prospect of big downpours. We have already had an instance of this during the summer.

Predicting exactly where the thunderstorms will hit is difficult. But the indications are that there will be a large number of lightning strikes. The concentrated rainfall is also liable to cause surface water flooding.

As a result the Met Office has issued a yellow warning for people in the region to be aware of the threat. It will be in force tonight, tomorrow and part of Friday.
