ORLANDO, Fla. - Tropical Storm Nana weakened to a depression after rapidly losing strength as it cut through northern Guatemala. Meanwhile, the National Hurricane Center is keeping its eye on several other systems, including one tropical wave with high odds of developing.

First, Nana moved inland of Belize early Thursday and is moving west-southwest at 14 mph, according to the NHC's 5 p.m. update. The storm has maximum sustained winds of 35 mph, and is about 220 miles west-southwest of Belize City.

Nana is expected to keep moving southwest through Central America and is forecast to become a remnant low while over the Gulf of Tehuantepec by Friday.

All watches and warnings for Nana were canceled Thursday afternoon.

Nana is expected to bring 3 to 6 inches of rain that could result in flash flooding in Guatemala and portions of southeastern Mexico, forecasters said.

Farther north, Tropical Depression Omar is hanging on and retains its maximum sustained wind speeds of 35 mph. Omar is moving east-southeast at 10 mph, but is expected to lose speed Friday. The storm is expected to become a remnant low Friday or sooner, and then should dissipate by Saturday in the mid-Atlantic.

Meanwhile, the NHC is monitoring three systems off the coast of Africa including one tropical wave with a 70% chance of becoming a tropical depression or a tropical storm in the next five days.

The wave is merging with a disturbance a couple of hundred miles south of the Cabo Verde Islands. Development is expected to happen slowly as it moves west at 15 mph. The wave has a 20% chance of developing in the next two days.

A broad area of low pressure located several hundred miles west-southwest of the Cabo Verde Islands is producing scattered showers and thunderstorms. The system has a 20% chance of developing in the next two days, but a higher chance, 40%, of developing early next week as the aforementioned tropical wave passes north of it Sunday.


Finally, another tropical wave is forecast to move off the coast of Africa over the weekend. As a result, an area of low pressure is expected to develop and move west early next week. The system has a 20% chance of forming into a tropical depression or tropical storm in the next five days.

The Atlantic has been busy with tropical storm thus far, and is expected to remain busy, according to the National Oceanic and Atmospheric Administration, which forecast an estimated total of 19 to 25 storms this year - the most it has ever forecast.

Hurricane season runs from June 1 to Nov. 30, with the statistical peak of activity coming Sept. 10.

The next named storms for the 2020 season would be Paulette and Rene.
