if you're planning a bank holiday barbecue, you might want to reconsider. 

The Met Office has issued a yellow 'be aware' warning for rain this afternoon and tomorrow (Monday). 

It covers the whole of the south of England and reads as follows:

Between 12:00 Sun 28th and 16:00 Mon 29th

Some areas of heavy rain will move north-eastwards during Sunday and into Monday across parts of southern England and Wales with some locally torrential downpours and thunder possible.

Many areas will see rain at times but the extent of the most intense and thundery downpours will be limited.

Only small areas are likely to see these downpours at any one time.

This could result in some disruption, with sudden flooding of roads, transport routes, homes and businesses possible.
