Heavy downpours led to delays on the roads and train lines in and around Glasgow.
Last night, more than two inches of rain fell on high ground in North Ayrshire, with an inch descending on Glasgow.
In the city, it meant Bilsland Drive in Maryhill was closed in both directions and drivers faced delays due to surface water on Great Western Road.
Blochairn Road at Siemens Street in the north-east was closed, and major flooding under the aqueduct forced the closure of Sandbank Street in Maryhill.
Glasgow City Council has now confirmed that both roads have reopened.
The council tweeted: "Motorists are advised that Bilsland Dr, Blochairn Rd and Sandbank St have all reopened after earlier closures due to flooding."
The A737 in Howwood, Renfrewshire, was closed in both directions and in East Dunbartonshire Robroyston Road in Lenzie and Switchback Road in Bearsden were both closed for a time.
On the trains, Scotrail warned of “severe disruption,” with trains suspended between Dalmuir and Springburn throughout rush hour.
They said services between Dalmuir and Lanark via Bellshill could be terminated at short notice.
There were no services at Clydebank and Yoker with services between Dalmuir, Lanark and Motherwell starting and terminating at Garscadden.
Meanwhile, signalling problems between Linlithgow and Edinburgh Park caused disruption between Edinburgh and Glasgow Queen Street during rush hour on Scotland's main rail artery.
Part of the M74 was also closed for three hours until 7.10am following a crash involving an articulated lorry at junction seven, northbound.
The driver was treated for minor injuries at Wishaw General Hospital following the incident at 4.10am. Police said inquiries are continuing.
Up to an inch more rain is expected to fall on high ground tonight around Glasgow and motorists can expect hazardous driving conditions due to standing water, mist and fog on the M77 and the M74.
The Met Office issued weather warnings for rain across Strathclyde.
Forecaster Dave Clark said: “There is a band of heavy thundery rain coming in overnight tonight and into tomorrow morning.
“Drivers can expect misty and murky conditions with fog on the M77 and the M74 going through tomorrow morning with surface water and spray on the roads.”
