As the Met Office puts out a yellow warning for heavy rain and thunderstorms in our region tonight, our weatherman Bob Crampton explains the traffic light warning system:
"Yellow, amber, red - that's the grading of Met Office warnings. There has been some confusion on the whole warning thing. It is simple - a sort of traffic light system.
"It relates to severe weather - fog, rain, wind, rain, ice and snow; these are the categories. A yellow warning is to "be aware" of one of the categories indicated. Amber is getting more serious; its "be prepared", while red is the most serious. It's rarely used and warns people to "take action" to protect their own safety.
"Tonight a yellow warning will come into force because of heavy rain and possible thunderstorms. It's really a heads-up to watch out for surface water puddling on roads, flashes of lightning and any hail that comes with a storm. It's likely that the heavy rain and storms will be very localised and certainly not everyone will experience them. It's also difficult to pinpoint their path across our region.
"The yellow warning runs from 23:15 tonight until 22:45 tomorrow."

A new report says more than a fifth of children in the south west are separated from their brothers and sisters when placed in foster care during the last financial year. The statistics are revealed in a Freedom of Information request from Action for Children. It wants more foster carers to come forward to make sure siblings aren't split up.
