THE Met Office has issued yellow warnings for three regions as heavy rain looks set to bring flooding chaos today.
Brits can brace for wet weather today as a band of rain pours across some areas which may cause water to rise.
Wet skies are likely to cause havoc for southern parts of England and Wales throughout the morning until 9pm.
Later in the day, heavy rain will likely move across eastern Scotland which has also been issued the advisory notice.
The downpour may cause flooding and disruption to travel until 9pm.

Met Office spokeswoman Nicola Maxey said the south and west of England could possibly experience thunder on Wednesday.
She told Sky News: “Showers could locally be heavy and there’s a chance you might see thunder, mostly in coastal areas to the south and the west,” she said.
“In general, any rain today will continue to push slowly eastwards across the country tomorrow, becoming persistent in the north, with gales in (the) northeast.
“Sunshine and heavy showers following into south and west later.”

Yellow is the least dangerous out of the weather warnings – it means “be aware”.
This potentially means cancelling plans, having to deal with travel delays, road and rail closures, interruption to power and the potential risk to life and property.
The Met Office predicts there could be as much as 50mm in localised areas.
That rain will continue to move East across the day which will also be heavy at times.
The North will also see some rain with the northeast also being hit with wind and gales.
Britain will continue to be hit with rain and strong winds for the rest of the working week, across all areas.
The northeast will also be hit by gales or even “severe gales,” according to the weather forecasters.
Although the miserable conditions will be eased with periods of “drier interludes” for many areas.
