A Status Orange wind warning has come into effect, with strong winds from Storm Callum coinciding with high spring tides tonight and tomorrow morning.

The warnings cover Cork, Kerry, Donegal, Galway, Mayo, Sligo, Clare, Dublin, Louth, Wexford, Wicklow, Meath, and Waterford.

Strong winds associated with the storm could reach speeds of between 100km/h and 130km/h.

It is expected to cause flooding along south and west coasts later tonight and tomorrow.

The Department of Housing, Planning and Local Government said the severe weather team has also met to co-ordinate its response to the storm.

In a statement following the meeting, the National Emergency Co-ordination Group said necessary arrangements are being put in place to ensure the safety of people who are sleeping rough.

According to Met Éireann it is likely that Kerry and Cork will be among the worst affected areas, along with western counties.

Speaking on RTÉ's Today with Sean O'Rourke, Met Éireann's Head of Forecasting Evelyn Cusack said that while localised flooding may happen on the east coast, widespread flooding was not expected in the region.

Ms Cusack said high tides and strong gales and winds are forecast with south-easterly winds up to gale force 8 or 9 gusting to storm force 9 overnight.

The Commission for Aviation Regulation has advised that some passengers scheduled to fly into or out of Irish airports tomorrow may experience some disruption as a result of Storm Callum.

Aer Lingus has announced that a number of flights on the airline's European network have been cancelled tomorrow due to the storm.

The Department of Education has advised schools and other education centres in areas affected by a Status Orange alert to remain vigilant.

Schools are advised to keep themselves appraised of any hourly and other updates from Met Éireann, and from their local authorities, local radio, and An Garda Síochána.

The department says that if in any doubt, schools should err on the side of caution.

It also says schools are empowered to make closure decisions if, in their judgment, and in the interests of child safety, it is prudent to do so.

It says decisions about school closures should be informed by, as well as prevailing and predicted conditions, any damage that might have been caused to school buildings overnight or at any time during the storm, and whether such damage, - where it exists, - might present a risk to child safety.

The Department says it will continue to monitor the situation and will follow any advice from the National Emergency Coordination Group.

Portable dam being installed at Spanish Arch

Galway City Council is installing a 80m portable dam at Spanish Arch and flood gates at various points in Salthill, ahead of the arrival of the storm.

More than 5,000 sandbags are being made available for people to collect at a number of locations around the city.

The sandbags are available at a council depot in Clarinbridge, with others being distributed to properties in Kinvara. 

Speaking on RTÉ’s Morning Ireland, the council's Acting Director of Services Gary McMahon said that a weather assessment team has been tracking the storm this week.
