The tropical wave we’ve been monitoring over the last several days, known as Invest 99-L, is struggling and continues to look very disorganized on satellite this morning to the northeast of Cuba. By early next week, the chance of its development is 60% if it survives into the Gulf of Mexico, the hurricane center said.

It was located 950 miles west-southwest of the Mexican peninsula of Baja California, and moving westward at five miles per hour. 99L will travel around the perimeter of a ridge of high pressure located along the southeastern coast of the United States. Conditions are not expected to get any better today as it moves to the west around 13 miles per hour.
Keep in mind this system has not formed yet, and large changes are possible in the forecast for the next several days. “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 by Sunday”.
As to where along the Gulf Coast the system will eventually track, it appears somewhere between Louisiana and the Florida Big Bend area. Tropical Storm Gaston is making its way across the mid-Atlantic but it is not expected to make landfall.
The hurricane center gave the system only a 10 percent chance of development but said it would reach the coast of Texas on Sunday and bring more rain to the area in the process.
Invest 99L could become a named tropical storm Thursday or Friday as it dumps heavy rains on Puerto Rico and Hispaniola. Be sure to check back in over the next few days for the latest forecast information. This region has a 90% chance of development over the next 5 days and could become a tropical depression over the weekend.
