Met Éireann explains: "The strongest winds associated with this event will occur during the night-time hours and Friday morning rush-hour commute.
"Even though the high winds will be the main concern, a spell of heavy and possibly thundery rain will occur too, making for an extremely windy and wet start, with squally conditions associated with the secondary cold front as it tracks north-eastwards up across the country."
Road users are being advised to take care, with debris possible on roads after the storm hits overnight.
The National Emergency Coordination Group met this afternoon.
It says crisis management teams and local coordination groups have been activated in the coastal counties affected.
Housing Minister Eoghan Murphy says he's contacted local authorities to ensure arrangements are in place to help rough sleepers.
I have asked all local authorities to activate measures to ensure the safety of those sleeping rough during Storm Callum. Extra emergency beds are in place and outreach teams will continue to work across the country.
