A two- to four-foot storm surge or rise in water is still expected along the coast to the right/east of where Alberto makes landfall.
The current projected path shows it will make landfall near Pensacola around 1 p.m. Monday as a subtropical storm, with winds of 65 miles per hour.
In Taylor County, there were voluntary evacuations for those in coastal zones and beach communities, mobile homes, RV parks and low-lying areas.
Brief tornadoes are possible from northern Florida into central and southern Georgia, southern SC and southeastern Alabama. Unfortunately for Apalachicola, the maximum storm surge should arrive at this morning's high tide, resulting in a total water level roughly 3.4 feet above the normal high tide.
Mark Bowen, the Bay County emergency management director, suggested people stay safe - preferably indoors. "This is definitely a risky storm", said David Roth, a meteorologist with the National Weather Service's Weather Prediction Center in College Park, Maryland. The rain could lead to flash floods and mudslides on the island.More news: Uber to bring transparency and allow users to pursue sexual assault claims
Even hotter temperatures are forecast for some areas Monday - with more records possible.
Forecasters say 2 inches (5 centimeters) of rain is expected on saturated ground with isolated areas getting up to 4 inches (10 centimeters) of rain.
The storm disrupted long holiday weekend plans from Pensacola in the Florida Panhandle to Miami Beach on Florida's southeastern edge. This is the area that has the potential to feel tropical storm force winds.
"We need to really be careful with that rainfall", Graham added, noting that the storm was moving slowly at some 14 miles per hour northwards.
Alberto is scheduled to make landfall on the Florida Panhandle early Monday, and the three states likely to bear the brunt of the storm have begun preparing states of emergency.
