LAFAYETTE, La. (KPEL) -- Hurricane watches have been posted from Morgan City to the Florida gulf coast as forecasters shift Tropical Storm Isaac's predicted path further to the west.

As of 11 a.m. Isaac was just north of Cuba, moving to the west-northwest at 18 miles per hour, with maximum sustained winds of 65 miles per hour.

The National Hurricane Center expects Isaac to slow down over the next 48 hours. It is expected to move over the Florida Keys at some point today or tonight.

"Though it is still too early to know how Isaac will impact Louisiana, we encourage our citizens to spend this weekend getting prepared for tropical weather early next week," says Kevin Davis, Director of the Governor's Office of Homeland Security and Emergency Preparedness.

"Check to make sure you have supplies like water, batteries, flashlights and medications on hand, walk around the outside of your home to pick up or secure any objects that might fly around in strong wind and check on your neighbors, family and friends to make sure they are safe and ready if a storm comes our way," Davis says.

On its current track, Isaac is expected to make landfall as a hurricane somewhere along the gulf coast Wednesday morning.
