Top winds for the weather system were about 40 miles per hour Thursday night.
Meanwhile, Isaac is a tropical storm that will eventually die out as it moves closer to the Yucatán Peninsula, according to Bridges.
The National Hurricane Center issues new updates at 8 AM, 11 AM, 2 PM, 5 PM, 8 PM, 11 PM, 2 AM, and 5 AM. When Isaac reaches the west-central Caribbean Sea in a couple of days, the shear may relax somewhat and the global models suggest that there will be an increase in mid-level moisture.
The governor of Georgia has declared a state of emergency after forecasts showed Hurricane Florence possibly taking a south-west turn.
Florence, a potentially life-threatening Category 4 hurricane, is on track to make landfall in North Carolina or SC on Thursday (Sept. 13).
The storm now appears to be on track to enter the Gulf of Mexico as a tropical wave early next week, meaning South Florida will hardly notice a thing.
"But it could have a positive effect on eastern parts because it could also bring tropical air".
A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours.
At 2 a.m., the storm was centered 625 miles (1,005 km) southeast of Cape Fear, North Carolina, moving at 17 mph (28 kph).
There is increased fear that Florence "will slow considerably or stall, leading to a prolonged and exceptionally heavy and unsafe rainfall event Friday-Sunday", the NHC said Tuesday. Swells generated by the storm could produce life-threatening surf and rip current conditions.
