Freezing weather conditions have caused disruption across Merseyside after record breaking low temperatures hit the region over the weekend.
Drivers were urged to slow down and drive carefully as the freezing conditions continue to cause problems, particularly on minor roads.
Liverpool John Lennon Airport is open, but passengers are being warned of possible delays.
Merseyrail ran a Sunday service on Wirral and Northern lines.
Many bus services were also affected, with Arriva saying no services would be running in Southport on Monday.
Travel operator Merseytravel said other areas affected included Lower Heswall and Skelmersdale, but all passengers were advised to check operators' websites before travelling and to allow extra time for journeys.
The Mersey Tunnels reported a normal service, but the Mersey Ferries were suspended until midday due to fog on the river.
The Met Office has said the freezing weather would continue throughout the week.
Meterologist Alan Goodman said: "We had a record low at Crosby on Sunday, that was -17C, in old money that's 1F, that smashed all records for Crosby.
"Checking down at the airport this morning it is -11, which is very, very low.
"These sort of temperatures, with daytime temperatures struggling to get above freezing, are certainly going to be with us for the rest of this week, I think we'll just about make it until Christmas Day as well."
