(Reuters) - A broad area of low pressure in the northwestern Caribbean Sea has a high 60 percent chance of becoming a tropical cyclone during the next 48 hours, the U.S. National Hurricane Center (NHC) said on Wednesday.
The storm system is moving toward the west-northwest at 10 to 15 miles per hour, the Miami-based weather forecasters said.
"Cloudiness and showers associated with this low continue to show signs of organization and a tropical depression could form before the disturbance reaches the Yucatan Peninsula on Thursday," the NHC said.
After Thursday, the weather system is forecast to move over the Gulf of Mexico, where upper-level winds would likely be a little less favorable for its development.
A separate low pressure system located a couple of hundred miles southeast of the Cape Verde Islands has a high 70 percent chance of becoming a tropical cyclone over the next couple of days, the NHC said.
