(CNN) – Tropical Storm Grace is the seventh named storm of this season, while Tropical Depression Fred degrades into a tropical wave.

Once a tropical depression, Grace has now strengthened and is a tropical storm located about 643 kilometers east of the Leeward Islands in the Atlantic Ocean, according to the National Hurricane Center.

The storm is expected to bring heavy rain and flooding, and has also triggered a tropical storm warning for parts of the eastern Caribbean, including the US Virgin Islands and Puerto Rico.

The maximum wind speed is approximately 72 km/h and is expected to intensify over the next few days.

According to the current forecast track, Grace Center is expected to move over the Leeward Islands Saturday night, the Virgin Islands and Puerto Rico on Sunday and the Dominican Republic on Monday. Weakness is expected early next week, after the system interacts with the Greater Antilles.

On Saturday morning, the US Coast Guard established port yankee case (which is determined when winds of 62-86 km/h are expected) for the ports of Puerto Rico and the US Virgin Islands, which means hurricane-force winds are expected within 24 hours.

The coast guard said in a statement that the ports are closed to all incoming commercial traffic.

“Recreational boat owners are advised to find a safe haven and to pay close attention to any changes in weather forecasts and small boater alerts over the weekend,” the statement said.

The Coast Guard also advised people to stay away from beaches and prepare to leave the area.

The track was released on Saturday morning for Tropical Depression Fred and Tropical Storm Grace, which are expected to continue over the next five days.

Farid may reorganize over the Gulf

A unique tropical depression retreated into a tropical wave late Saturday morning, according to the National Hurricane Center. All warnings are turned off.

Currently, Fred’s remains are located about 80 kilometers from Havana. On Saturday, the country flooded the island with rain.

Despite the weakening, conditions are favorable for some strengthening and Fred is expected to become a tropical storm again on Sunday.

It is expected to make landfall along the northern Gulf Coast on Monday night as a tropical storm.

A state of emergency was issued Friday in 23 counties, including Bay, Calhoun, Citrus, Dixie, Escambia, Franklin, Gadsden, Gilchrist, Bay, Holmes, Jackson, Jefferson, Lafayette, Leon, Levi, Liberty, Manatee, Ocaloosa, Santa Rosa, Taylor, Cola Walton, and Washington, according to Florida Governor Ron DeSantis.

As of Monday, 70 to 120 mm of rain is expected with local amounts of 200 mm in the Keys and southern Florida. Fred is expected to continue north across the bay, making a touchdown near the Alabama and Florida border Monday night.

Across Big Bend and northwest Florida, rainfall is expected from 70 to 170 mm with isolated heights of 250 mm.

Starting Monday, the effects of heavy rain and flooding could extend to parts of the interior in the southeast.
