Troup County could get more than 4 inches of rain from Tropical Storm Isaac after it makes landfall late Tuesday on the Gulf coast.

“(The forecast) is changing quite rapidly,” said Dennis Knight, Troup County Emergency Management director. “The further west it moves, the less impact it will have here. With every briefing it’s looking better.”

Rain and flooding continue to be the main threat from the storm, however, that’s predicted to come ashore as a Category 2 hurricane seven years to the date of Hurricane Katrina. With the rain bands comes the possibility of tornadoes. Most of the rain should fall Tuesday and Wednesday.

“Everyone should keep an eye on the weather,” Knight said. “If you have a weather radio, make sure it’s working.”

Nate Mayes, a forecaster with the National Weather Service, also cautioned residents with interests or family members along the Gulf to monitor the situation closely. He also warned everyone to fill up their cars with gas before the storm hits.

“They’ve already evacuated the oil rigs, so you know gas is going to go up,” he said.

The forecast for the week includes a 60 percent chance of rain Tuesday, going up to 70 percent on Thursday.
