The Joint Typhoon Warning Center noted that Cilida had intensified rapidly, by 55 knots (63 mph/102 kph) in 24 hours. Rapid intensification is expected to continue in the near term as warm sea surface temperatures and light outside winds remain. However, Cilida is expected to run into increasing vertical wind shear (which can weaken a storm) ahead of a developing mid-latitude trough or elongated area of low pressure.

On Dec. 20 at 10 a.m. EDT (1500 UTC) Cilida's maximum sustained winds had reached 90 knots (103.6 mph/166.7 kph). Cilida is currently a Category 2 hurricane on the Saffir-Simpson Hurricane Wind Scale. It was located near 13.4 degrees south latitude and 58.9 degrees east longitude, approximately 427 nautical miles north-northeast of Port Louis, Mauritius. Cilida was moving southwestward and was undergoing rapid intensification.
