Those who register will receive alerts about safety developments and possible airport disruptions.
The ministry also warned that drone or missile threats could trigger air raid sirens on the island, and reminded travellers that airspace over Cyprus could be closed to civilian traffic at short notice.
What to do if flights are disrupted
Travellers facing delays or cancellations are advised to monitor their airline's app and website, and to contact their tour operator if travelling as part of a package.
The ministry stressed that only airlines and tour operators can rebook flights or issue refunds, and that responsibility for meals and accommodation during disruptions lies with them.
Those stranded without funds for accommodation can contact the Polish consulate in Nicosia by email at nikozja.kg.dyzurny@msz.gov.pl, providing their personal details, location and the help needed.
The consulate can also be reached on +357 99 72 90 93.
In the event of an air raid warning
Anyone outdoors should seek shelter in a solid, enclosed structure.
Those already inside a building should move to the lowest floor, away from windows.
The ministry specifically advised people not to head to the embassy or consulate in such situations, as these are not designated shelters.
Official shelters can be found via the SafeCY mobile app, or by calling Cyprus Civil Defence on +357 22 403 451 or +357 22 403 452.
Travellers are also advised to avoid military bases and other critical infrastructure, and to follow instructions from local authorities.
