There’s about a 50 percent chance of rainfall, said Tara Goggins, a meteorologist for the National Weather Service in Birmingham.
Rainfall, if it does arrive, is expected to reach about 1 to 2 inches as Isaac’s rain bands move northward, Goggins said.
“However, things right now are sort of in a constant state of minor changes here and there,” she said. “So things can definitely change over the next day or two.”
Isolated tornadoes or flash flooding are possible, and those same threats can carry throughout the day on Wednesday and into the late evening on Thursday.
“Now, with Calhoun County being a little bit farther removed from the actual center of the system, your impact will not be as great as the impacts in the southwestern portions of our forecast area,” Goggins said.
Amtrak announced Monday that all service to and from New Orleans is suspended on Tuesday and Wednesday due to the forecasted landfall of Isaac.
Crescent Trains 19 and 20, which stop in Anniston, will have no service in Alabama, Mississippi and Louisiana until further notice, Amtrak officials said.
Passengers who have already bought tickets can receive a refund or voucher for future travel. Amtrak spokesman Marc Magliari said more information will be available as the storm situation develops.
Calhoun County Emergency Management Director Jonathan Gaddy said local emergency officials are closely monitoring the development of the storm.
“Currently, Calhoun County is expecting limited impact from the tropical storm,” he said. “The forecast path is uncertain as always and we always are ready in case the storm shifts more to the east.”
Gaddy suggested residents keep up with the development of the storm and be ready in case anything changes.
“I think this is a great opportunity for citizens to take a look at their emergency preparedness supplies,” Gaddy said. “Even if this storm does not directly affect us, another one later in the season could.”
