The Met Office has extended the yellow weather warning for parts of North Wales including Denbighshire and Conwy.
The original snow and ice weather warning is expected to lead to things like potential road blockages and communities being "cut off for several days".
It covers the entire North Wales region including Flintshire, Denbighshire, Wrexham and Conwy and is set to come into force at 7 am Thursday, March 9 and will last until 2 pm on Friday, March 10.
This yellow weather warning remains in place.
However, travel disruptions caused by snow and ice have resulted in the yellow weather warning being brought forward for parts of Conwy and Denbighshire.
In areas like Llanwrst, Ruthin and the outskirts of Wrexham a yellow weather warning has been introduced effective immediately.
What to expect from Met Office snow warning in North Wales
The Met Office said the yellow weather warning was due to spells of snow and icy patches causing travel disruptions.
They have said people could expect possible travel delays on roads, with conditions potentially leaving passengers and vehicles stranded.
Bus and train services may be delayed or cancelled, while some road closures and longer journey times are possible.
Some rural communities could become temporarily cut off, power cuts may occur and other services may be temporarily affected.
The Met Office warned untreated pavements and cycle paths posed an injury risk from slips and falls on snow-covered or icy surfaces.

A Met Office added: “Snow could develop quite widely across the warning area on Thursday and Friday as a potentially quite deep area of low pressure moves across the UK.
"Parts of Northern Ireland, north Wales and northern England are currently expected to see the worst of the conditions on Thursday, with parts of Scotland and northern England then seeing the heaviest snow on Friday.
"Event totals could bring 5 to 10 cm of snow to many locations, even at low elevations, with potentially 15 to 20 cm accumulating across the northern portion of the warning area.
"Higher elevations of the North Pennines, Southern Uplands, higher parts of the Central Belt and the southern Highlands may see as much as 30 to 40 cm of snow in places.
"In addition, there is potential for strong winds, which may lead to blizzard conditions and drifting of lying snow."
