Wind warnings for Irish coastline

In the Republic of Ireland, wind warnings remain in place around the entire coastline on Sunday.

Irish Weather service, Met Éireann, has warned that it will be very windy with strong and gusty southwesterly winds.

This could lead to large coastal waves, some fallen trees, and travel disruption.

Coldest night this winter

Meanwhile, Northern Ireland had its coldest night of winter, so far, on Friday night, when temperatures fell to -7C.

It was recorded at the weather station at Katesbridge in County Down, which often reports the lowest temperature across the island.

The hamlet sits in a frost hollow where, in the winter, cold air builds up to allow it to become so cold.

In County Tyrone, rare "ice pancakes" were spotted on the Edenderry River on Saturday morning.

They are caused by the freezing of foam floating on a river's surface.

What is the coldest it's been in Northern Ireland?

The lowest temperature ever recorded in NI was -18.7C at Castlederg in Tyrone during the big freeze of December 2010.

The lowest temperature ever recorded on the island of Ireland was -19.1C at Markree in Sligo in January 1881.

When does winter end?

The answer is simple.

It depends on which calendar you follow - ancient Celtic or Irish, meteorological, or astronomical.

The ancient Celtic calendar, also known as the Gaelic or Irish calendar, dates back centuries and is still followed by many in Ireland today.

It marks the winter season in November, December and January, with spring starting on 1 February - or St Brigid's Day.

The meteorological calendar is also grouped into three full months but the seasons begin a month later with December, January and February making up the winter season.

However, the astronomical calendar seasons are defined by two solstices and two equinoxes.

These are determined by Earth's tilt and the sun's position over the equator.

The winter season starts on the winter solstice, around 21 December, and ends on the spring equinox, around 20 March.
