The Met office has increased its weather warning to an Amber status for areas including North West England and Southern Scotland for the 18th July.
The amber warning means 'Be prepared' and is one stage higher than the yellow warning previously in place which means be aware.
The Met office say heavy rain is expected across northern England and southern Scotland. They say between 20 and 30mm of rain is expected but in parts of southern Scotland between 50 and 80mm could fall.
Because of the already saturated land the rainfall could lead to flooding in some parts.
