The Met Office has issued Merseyside more severe weather warnings for heavy thundery showers.
The weather warning is in place for 1pm-9pm on Tuesday as heavy thundery showers are expected to develop.
Heavy, thundery showers will turn locally torrential with the risk of hail on Tuesday afternoon and evening across parts of the North West.
These will be slow moving, and whilst many places will miss the worst, they will bring some localised torrential downpours.
A forecaster at the Met Office said: “Warm, moist air will turn unstable as the ground heats up, releasing heavy, thundery showers.
“Many of these will be over high ground, but will drift into lower-lying areas too.
“There could be more than 20 mm in the hour locally, with more than 50 mm in a few hours possible”.
