The National Hurricane Center says the threat is growing for a tropical depression, at minimum, to form in the western Caribbean Sea by the weekend.
A tropical wave is moving towards a frontal boundary and the interaction between the two is leading for a high chance of development.
"Conditions are expected to be conducive for a tropical depression to form by early next week, but only if the system moves and remains over the waters of the northwestern Caribbean Sea or southern Gulf of Mexico," said a tropical weather outlook from the NHC. "Development will become less likely if the system moves over the Yucatan Peninsula or northern Central America."
Forecasters warn that, regardless of development, the threat remains for heavy rains and possible flash flooding for parts of southeastern Mexico, Central America and western Cuba for the next few days.
Right behind that, another tropical wave is moving towards the western Caribbean and it also has a chance for development, albeit a low one.
For now, it is too early to say if either system will threaten the north-central Gulf Coast. More fall fronts are expected to help keep the systems away from Louisiana, but it's a reminder the hurricane system is not done just yet.
The next names on the 2020 list are the Greek letters Gamma and Delta.
