Tropical storm chance increases in Atlantic
The agency was monitoring a storm system called Invest 94L about 800 miles west-southwest of the Cabo Verde Islands.
The storm hasn't changed much in recent hours, but environmental conditions are favorable for a tropical depression or tropical storm to form in the Atlantic Ocean.
There's a 70 percent chance a depression will form in two days, 80 percent chance in five days.
The storm is traveling westward or west-northwestward at 10 mph to 15 mph toward the U.S. Southeast coast.
If Invest 94L becomes a tropical storm, it will be the fourth named Atlantic storm of the season -- Don. Tropical Storm Cindy caused flooding along the Gulf Coast shores of Texas, Louisiana, Alabama, Mississippi and Florida in late June. ■
