Forecasters say there is a chance flooding could occur after heavy rain showers arrive in Ayrshire later this evening
The Met Office put a yellow weather warning for rain in place for midnight this evening.
Experts say the weather front — which is expected to extend into East and South Ayrshire — could last until 12 noon on Wednesday.
And the forecasters have also said there is a small chance that homes and businesses could be flooded, causing damage to some buildings.
The warning reads: "Persistent, and at times heavy rain, will develop across Northern Ireland, southern Scotland and the far north of England during Monday night.
"Rainfall accumulations of 20-30 mm are expected quite widely and some places, mostly over higher ground, could see 30-50 mm rain.
"This wet weather will clear eastwards early on Wednesday.
"Later on Tuesday rain will also turn to snow over hills, initially down to 300-400 m and then down to 100-200 m Tuesday evening and night.
"The most widespread snow will be over southern Scotland where accumulations of 2-5 cm are possible above 200-300 m and 5-10 cm may fall above 300-400 m."
