Tropical Storm Cristobal slowly moved north in the Atlantic, dumping heavy rain on the Bahamas and Turks and Caicos islands on a track away from the U.S., the National Hurricane Center said.
Cristobal had top winds of 60 miles (97 kilometers) per hour as of 5 p.m. East Coast time and was 670 miles southwest of Bermuda, where the weather service issued a tropical storm watch, the center in Miami said. The system was moving north- northeast at 5 mph.
“Gradual strengthening is expected over the next 48 hours and Cristobal is forecast to become a hurricane on Wednesday,” the center said in an advisory.
Cristobal is the third named storm of the Atlantic season that began June 1. The current track forecast has it staying far out to sea, where it won’t be a threat to the U.S. or Canada. The system is expected to pass west of Bermuda.
Before it leaves the Bahamas and Turks and Caicos, it may drop 4 to 8 inches (10 to 20 centimeters) of rain.
The hurricane center is also watching a disturbance about 1,100 miles west-southwest of the Cape Verde Islands that has a 30 percent chance of becoming a tropical system in the next five days.
In the Pacific, Tropical Storm Karina and Hurricane Marie are moving away from land. Dangerous swells being kicked up by Marie, a Category 4 system, are expected to reach Southern California tomorrow, the center said.
