Update at 12:15 a.m. Wednesday

Hazard Management Cayman Islands issued an all clear at midnight on a tsunami threat from the Honduras earthquake.

It noted that minor sea level fluctuations of up to 12 inches above or below the normal tide may occur over the next few hours.

HCMI is urging people to “remain observant and exercise normal caution near the sea. Otherwise, no action is required.”

Update at 11:00 p.m. Tuesday

Hazard Management chiefs are indicating that there has been no sign of abnormal sea level rise around the coast of Cayman.

They are advising people to stay away from the coast as a precautionary measure, according to Dani Coleman, acting head of the unit.

Hazard Management Cayman Islands said the threat of flooding from a tsunami was unlikely.

“The tsunami gauge at the port in George Town has not registered any abnormal sea level rise and the threat from inundation from tsunami waves is considered very unlikely,” a spokesperson said.

“Forecast models initially suggested a 1 to 3 foot was possible but this does not appear to have affected the Cayman Islands. However, persons should stay off the coastline and beach areas, particularly the west coast, because tsunamis are a series of waves, and while the threat is very small, persons should exercise caution.”

Update at 10:40 p.m. Tuesday

The U.S. Tsunami Warning System has removed the Cayman Islands from its tsunami advisory map.

Puerto Rico and the Virgin Islands remained under advisory, while Mexico, Cuba and Honduras were advised to remain on watch.
