The Economic Community Of West African States (ECOWAS) has repeatedly called on Jammeh to respect the result of the December 1 election and step down after 22 years in power.
Jammeh on Tuesday declared a state of emergency as Barrow, who is currently in Senegal, maintained his inauguration will go ahead as planned on Thursday on Gambian soil.
At Senegal's request, the Security Council will discuss the crisis in the West African country on Wednesday, diplomats said.
The African Union has said it will no longer recognize Jammeh as head of state as of January 19.
UN envoy for West Africa Mohamed Ibn Chambas last week told the council that ECOWAS was prepared to ask the council to approve the deployment of troops to the Gambia.
The council last month demanded in a unanimous statement that Jammeh recognize the outcome of the election and transfer power to Barrow.
