The cold snap which brought a dusting of snow and frost to some higher areas is set to continue today before heavy rain moves in tomorrow, according to Met Eireann.
Sub-zero temperatures overnight on Sunday led to a dusting of snow and frost over the Wicklow Mountains early yesterday. The trend is to continue today with frost settling in many areas early this morning following a cold night during which temperatures were due to drop to -2C.
Drivers are urged to exercise caution when returning to work today after the October bank holiday weekend, with a risk of icy patches early on, especially in Ulster and north Connacht.
However, the frosty start will give way to a largely dry day today with some sunny spells in Leinster and Ulster but cloudier conditions elsewhere and occasional showers along the east coast.
Fresh easterly winds will keep daytime temperatures on the cool side, with the mercury not expected to exceed 8C to 11C. Tomorrow will see the start of a period of unsettled weather as wet and windy conditions move in across the country.
Hurricane Pablo, the second most northerly hurricane recorded in the North Atlantic since records began in 1950, churned up water west of Iberia on Sunday, but dwindled to a post-tropical storm yesterday and is not expected to have a huge impact here, according to Met Eireann.
However, a low pressure system will bring heavy rain - especially to southern and western coastal areas - tomorrow morning before it begins to clear in the south-west by afternoon and spread dry weather to all areas by tomorrow evening.
Winds will be fresh to strong before the rain clears. The rain will herald milder temperatures of 10-15C.
