The U.S. Geologic Survey recorded a magnitude 5.8 earthquake underwater 103 miles off George Town on Sunday night.
Sunday night also brought about 3 inches of rain to Grand Cayman as part of a late-season tropical disturbance forming south of the Cayman Islands.
Most people on Grand Cayman did not notice the earthquake, which occurred at 7:39 p.m. amid Sunday’s thunderstorms. However, monitoring sites picked up weak tremors from the deep-sea quake, and at least one person on the U.S. earthquake monitoring site reported feeling the movement.
According to Cayman Islands National Weather Service forecaster Avalon Porter, Sunday’s rain came from a tropical system close to Panama. The National Hurricane Center in the U.S. gives the tropical disturbance a 10 percent to 20 percent chance of turning into a more organized cyclone in the next few days as it stays stationary, or possibly drifts westward.
Mr. Porter said he expects the cloudy weather here to clear up for Tuesday. He said almost 3 inches of rain fell at the Grand Cayman airport overnight as thunderstorms moved across the islands. The Weather Service forecast calls for 10- to 15-knot winds and moderate waves of 3 to 5 feet.
The earthquake, an estimated 5.6 miles deep on the fault running south of the Cayman Islands, caused no damage and appeared to pass almost unnoticed by residents on Grand Cayman.
