On Sunday evening, Tropical Storm Grace diminished to a tropical depression, but it continued to menace Haiti and the Dominican Republic with torrential rains.
The National Hurricane Center said in an 11 p.m. AST update that the storm’s eye was about 120 miles south-east of Santo Domingo, Dominican Republic, and 260 miles east-southeast of Port Au Prince, Haiti. It had maximum sustained winds of 35 miles per hour and was travelling west-northwest at 15 miles per hour.
According to the forecaster, Grace is generating torrential rain in Puerto Rico, which might lead to flash flooding and mudslides across Hispaniola Island on Monday.
Grace was the sixth named storm of the Atlantic hurricane season and joined Tropical Depression Fred churning further west in the Gulf of Mexico.
Grace was expected to follow Fred’s journey, likely making landfall on Puerto Rico and Hispaniola before skirting Cuba and taking aim for the Florida peninsula. Fred diverted further west after passing near Cuba.
“Both the future track and intensity of Grace have a high level of uncertainty,” the NHC said. “In the end, the exact track of the center and the intensity of the system will likely not be as important as the heavy rainfall that is forecast to fall across the Leeward Islands and the Greater Antilles during the next few days.”
The NHC said heavy rain was excepted across Puerto Rico over night and the Dominican Republic and Haiti on Monday.
Tropical storm warnings for the U.S. Virgin Islands, and Puerto Rico were discontinued. A tropical storm watch was in effect for the entire coast of the Dominican Republic and the entire coast of Haiti.
Grace follows five other named storms in the Atlantic basin so far this year — Ana, Bill, Claudette, Danny, Elsa and Fred. Of those five, Elsa was the only one to gain hurricane strength.
