Chances of development increase for two systems in the Atlantic

ORLANDO, Fla. - Nana has weakened back to a tropical storm after barreling toward Belize and making landfall as a Category 1 hurricane.

Meanwhile, the National Hurricane Center (NHC) says the chances of development for two other systems in the Atlantic have increased. 

On Thursday evening, the U.S. National Hurricane Center reported that the center of Nana would move over western Guatemala and southeastern Mexico before crossing into the Gulf of Tehuantepec on Friday.  The storm had maximum sustained winds of 35 mph.

Meanwhile, Tropical Depression Omar is located 310 miles north northeast of Bermuda. 

"Omar is moving toward the east near 14 mph and this general motion is expected to continue through tonight, accompanied by a decrease in forward speed," the NHC said. "A turn toward the east-northeast and northeast is expected Friday and Friday night."  

Forecasters are also watching a broad area of low pressure located over the eastern tropical Atlantic several hundred miles west-southwest of the Cabo Verde Islands. The system has a 40 percent of developing over the next 5 days, according to the NHC.
