A flood alert has been issued across the north-east, following a quick thaw in the area.
The Scottish Environmental Protection Agency (Sepa) last night warned that the after-effects of days of severe weather could heap further misery upon the region.
The flood alert applies to Aberdeen City and Aberdeenshire, amid fears that the rivers Don and Dee could burst their banks due to melted snow and hours of rainfall.
A Sepa spokesman said: “Persistent rain is forecast to affect the area.
“This, in combination with melting snow in lower areas, brings a risk of flooding from surface water.
“There is also a risk of flooding from smaller watercourses in lower lying eastern areas.”
Flooding began to cause headaches for some commuters yesterday afternoon.
Trains to Aberdeen were affected as surface water on the line at Montrose prevented passengers from returning to the city by rail.
The Edinburgh and Glasgow to Aberdeen and Inverurie services instead terminated at Dundee, while Scotrail staff worked to remove the water from the tracks at around 4pm.
Replacement buses were arranged while those efforts were ongoing, and the line reopened between Dundee and Aberdeen about 30 minutes later.
A Scotrail spokesman confirmed that trains between the two cities were subsequently placed under a speed restriction because of the conditions, which caused disruption to services for the rest of the night.
Meanwhile, Aberdeenshire Council acted quickly to clear surface water from the South Deeside Road at Blairs.
It is understood that the problem was caused by a blocked culvert, which was repaired at about 4.30pm.
