Topical Depression 28 formed over the Caribbean Saturday afternoon and is expected to strengthen into a named storm by Sunday, the National Hurricane Center reported on Saturday.
The Depression is currently located 240 miles south-southeast of the western tip of Cuba, with maximum sustained winds of 35 mph, according to an 11 p.m. update by the National Hurricane Center in Miami.
Tropical Depression 28 will continue moving north-northwest, reaching the southern portion of Cuba on Sunday, where it will form into Tropical Storm Zeta - the 27th named storm of the 2020 Hurricane season.
Meteorologists forecast that the storm will eventually turn into a Hurricane by Tuesday over the southern Gulf of Mexico, keeping the center of the storm far away from South Florida.
But the broad counter-clockwise flow around the storm will pull up moisture all weekend.
A Flood Watch is in effect for Miami-Dade and Broward counties through Sunday evening.
