Sandbags were delivered to some streets in Penketh as Warrington South MP Sarah Hall warned people to “stay vigilant” before water levels receded.
She said: “I know how worrying it can be when flood alerts are issued, especially for families who have experienced it before.”
There had also been a handful of alerts across Merseyside including parts of Liverpool and the Wirral.
In Lancashire, the alerts included areas around the River Darwen in Ewood, and Waterfall in Blackburn.
The warnings meant flooding was expected, and residents and business owners were urged to act to prevent damage to their properties, the Environment Agency said.
A severe yellow weather warning for heavy rain was also issued by the Met Office from 09:00 BST on Saturday through to 06:00 BST on Sunday.
