The hurricane center said dry air near 91L could slow its development.
The National Hurricane Center on Thursday decreased the odds that Invest 99L will develop into a tropical depression.
Chances for hurricane formation remain at 30 percent for the next five days. Gaston is expected to weaken over the next 24 hours as it moves into cooler waters.
Although the forecasts Friday are a relief, Grigsby said Louisiana residents need to keep the system in mind throughout the weekend and watch for updates.
Meanwhile, forecasters are keeping an eye on a low-pressure system about 200 miles northwest of Puerto Rico, which could become a tropical system over the weekend.
Madeline’s centre is located about 1,235 miles (1,990 kilometres) east of Hilo, Hawaii and moving towards the west-northwest at a speed of 12 miles (19 kilometres) per hour. This low is forecast to move westward and then west-northwestward at about 10 miles per hour 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 broad area of low pressure is associated with a tropical wave.
The second area that has gotten more attention – Invest 99L – continues to struggle to get organized. Models should begin to come into agreement Friday as the system moves toward the Bahamas. If it crosses into the Central Pacific it will be called Ulika.
The NHC advises interests in the northwestern Bahamas and Florida to monitor the progress of this disturbance since it is increasing likely that some impacts, at a minimum heavy rains and gusty winds, will occur beginning this weekend..

At 11 a.m., Tropical Storm Lester was 530 miles southwest of Baja California with sustained winds of 70 mph. People should also have storm supplies and an emergency plan in place, whether or not the storm hits Hawaii. If it continues west, it could fizzle as it gets ripped apart over the mountains of Cuba.
