The National Hurricane Center is now tracking three tropical systems as well as Tropical Storm Gaston. While Gaston is not headed our way the three tropical systems are expected to influence weather in the U.S.
A weak area of low pressure located located south of Andros Island in the Bahamas continues to produce disorganized showers and thunderstorms mainly to the south and east of its center. This system is moving northwestward through the Straits of Florida at about 10 mph. Some development may occur when the system moves across the eastern Gulf of Mexico next week.
Heavy rains, with the potential to cause flash floods and mud slides, are likely to continue over Hispaniola today. This activity is expected to spread over eastern and central Cuba over the weekend. Gusty winds and locally heavy rainfall are likely over portions of the Bahamas, and will spread into parts of southern Florida and the Florida Keys late this weekend.
The National Hurricane Center now estimates the probability of this system becoming a tropical depression or storm within the next 48 hours at 20 percent. The odds of tropical formation within 5 days is now 40%.

A second area of disturbed weather is located located about a hundred miles south of the coast of southwestern Louisiana. This system is producing disorganized shower and thunderstorm activity over the north-central Gulf of Mexico. This system is not expected to develop into a tropical storm or hurricane before it reaches the coast of Texas later this weekend.
Heavy rainfall is possible along the Gulf Coast from Louisiana to southeastern Texas during the next few days.
The National Hurricane Center now estimates the probability of this system becoming a tropical depression or storm within the next 48 hours at 10 percent. The odds of tropical formation within 5 days is also 10%.

The third system being watched is a broad area of low pressure centered a little over a hundred miles south-southwest of Bermuda. The associated shower activity is currently disorganized. However, data from the NASA/NOAA Global Hawk aircraft indicate that the low is producing winds near 35 mph east of the center. This low is forecast to move westward and then west-northwestward at about 10 mph toward the coast of the Carolinas during the next few days, but any development is likely to be slow to occur due to the system's proximity to dry air.
The National Hurricane Center now estimates the probability of this system becoming a tropical depression or storm within the next 48 hours at 30 percent. The odds of tropical formation within 5 days is also 30%.
The National Hurricane Center will be issue an update on these tropical systems at 2:00 PM EDT.
