Overnight Dave Tolleris meteorologist says the risk has gone down slightly according to overnight computer models. If it passes into the warmer waters of the Gulf of Mexico early next week, it could become a hurricane. It has a 40 percent chance of development over the next 48 hours.
According to the National Hurricane Center (NHC) in Miami, upper-level winds are expected to remain unfavorable for significant development during the next day or so while the system moves west-northwestward at about 10 miles per hour. The storm was located about 600 miles (970 kilometers) east of Bermuda.
The U.S. National Hurricane Center in Miami said Sunday that the depression is located 60 miles (100 kph) south of Key West and is moving west at about 9 mph. Heavy rains are likely to continue in Cuba today.
The tropical disturbance straddling the Greater Antilles called "Invest 99L" in meteorological circles, keeps providing challenges in future strength and impact projections for Florida and the Gulf region. He adds, "Upper-level winds are not conducive for significant development".
The National Hurricane Center is watching several areas of low pressure in the Atlantic and the Gulf of Mexico.
The center said the disturbance is better defined and producing a large, but disorganized, area of showers and thunderstorms.
"Any development of this system is expected to be slow to occur while it interacts with the terrain of Cuba through Sunday", the center said.
