PEARL (AP) — Mississippi Gov. Phil Bryant has declared a state of emergency as officials prepare for a hit from what’s now Tropical Storm Isaac.

Weather forecasters told Bryant and other state officials meeting Sunday at the state Emergency Operations Center that tropical storm winds could begin along the Mississippi coast Monday night and could last into Wednesday. National Hurricane Center Director Rick Knabb told Bryant on a conference call that forecasters expect Isaac to strengthen into a hurricane and drive a storm tide of 6-12 feet into coastal estuaries.

Knabb said forecasters are still having a hard time predicting where Isaac’s center will make landfall. It could come ashore Wednesday morning, seven years to the day after Hurricane Katrina killed more than 200 Mississippians and caused billions of dollars in damage.
