The Met service has issued a yellow warning for heavy rain and storms on Friday evening until 5pm on Saturday.
The service said rain and isolated storms are expected to affect the area between those times.
The rain may exceed 50mm in certain areas, the Met service said.
Earlier, the service said a low-pressure system moving east from Italy was expected to affect Cyprus from Friday evening, with heavy rains and thunderstorms.
The service said intense rain and thunderstorms will prevail, while snow or sleet will fall in the Troodos region.
Temperatures are expected to drop to 5C in the mountains, where frost may form.
On Saturday, more rainy and stormy weather is expected, but by the afternoon this will change to more a sunnier outlook.
Temperatures over the weekend are not expected to change, remaining at levels normal for the time of the year.
The fire service is ready to respond to any incidents which may occur due to the stormy weather, the department’s spokesman Andreas Kettis said.
“From 6am on December 12 until 6am this morning, the service responded to 17 calls, six in Larnaca and 11 in Famagusta,” he said.
“The incidents concerned towing vehicles with people trapped inside on flooded roads and pumping water from flooded buildings.”
