Weather forecasters expected Grand Cayman to get about an inch of rain Wednesday, and say a tropical wave moving in from Cuba could bring another inch Thursday.
Forecasters predicted temperatures to reach the low 90s Fahrenheit Wednesday, but with the system moving in, highs Thursday will only reach into the upper 80s.
Commuters woke up Wednesday morning to thunder, lightning and heavy rains. Traffic was snarled on the streets, with several inches of water sitting on many low-lying sections of Cayman’s roads.
Cayman Islands National Weather Service Chief Meteorologist Kerry Powery said, “We’re not particularly expecting much flooding, but we may see water settling on the road.”
Mr. Powery said the rain Wednesday and Thursday will come from separate weather systems. Wednesday’s rain, Mr. Powery said, is from a cyclonic weather system over northern Honduras, that was a rotating weather system similar to what could turn into a tropical storm.
The tropical wave, which passed over Haiti Wednesday, will begin dropping rain in the Cayman Islands overnight. Forecasters with the U.S. National Weather Service say the wave is moving westward at 15 knots.
Three cruise ships with more than 10,000 passengers between them stopped in Grand Cayman on Wednesday, and many passengers took the tenders into George Town, only to be greeted with a day of on-and-off storms. Two cruise ships are scheduled to call in Grand Cayman Thursday.
Cayman forecasters say seas will be moderate Thursday with wave heights of 3 to 5 feet and easterly winds at 10 to 15 knots, but winds will pick up and seas will be rougher during rain showers.
