But director Arona Ngari predicts the category two cyclone will fade out before it reaches the country.
The cyclone ravaged parts of Fiji with heavy rain and destructive winds yesterday.
Ngari said the Met Service was closely monitoring Sarai and early predictions were that it could lose out its energy before getting here.
“It’s moving very slowly. There are a couple of models showing it will fall short of us and the other one is showing that it will run out of energy before it reaches us,” Ngari said.
If Cyclone Sarai remained strong on its path, then the Cook Islands could expect some bad weather by Thursday next week, Ngari added.
“The public needs to be cautious of any unusual turn in the weather especially out at sea. People also need to be mindful of high tides that can enhance the effect of storm surge.”
Sarai is the second tropical cyclone in the 2019/20 season in the Pacific Islands region.
According to AFP, flights have been grounded and nearly 2000 people have been forced to flee their homes in Fiji as Cyclone Sarai lashed the Pacific island nation with heavy rain and destructive winds.
Packing wind gusts up to 140km/h, Sarai brought down trees and cut power supplies while stranding thousands of holidaymakers as flights to and from Fiji were either cancelled or rescheduled, AFP reported.
Fiji Airways and Fiji Link cancelled more than 130 flights yesterday to and from the archipelago, including flights to and from Australia.
