A broad area of low pressure in the northwestern Caribbean Sea may develop into a tropical depression before it reaches the Yucatan Peninsula of Mexico, according to the National Hurricane Center.
As of 2 p.m. EDT, the system was moving toward the west-northwest at 10 to 15 mph. It could turn into a depression before it reaches the Yucatan on Thursday, according to the Hurricane Center.
Afterwards, it is expected to move over the Gulf of Mexico, "where upper-level winds will likely be a little less favorable for development," the Hurricane Center said.
Forecasters said there was a 60 percent chance that a tropical cyclone could form in the next 48 hours and a 70 percent chance it could form in the next five days.
"Regardless of whether or not a tropical cyclone forms heavy rains and gusty winds are forecast to spread over the Yucatan Peninsula and Belize during the next day or two," the Hurricane Center said.
A second system in the Atlantic Ocean a couple hundred miles southeast of the Cape Verde Islands is also gathering strength, and could develop into a depression later on Wednesday or on Thursday, the Hurricane Center.
There was a 70 percent chance of it developing into a cyclone over the next two days, and 80 percent over the next five days. It was moving westward at 10 to 15 mph.
