The water level in Franklin and Wakulla Counties was already higher than usual Sunday morning, but this is nothing compared to the tidal surge that's expected to rush the shores early Monday morning.
Joe Blanchard, Wakulla County Director of Emergency Management, says, "We've got a high tide in the morning just after midnight. That tide does not go down very much tomorrow and so we're looking at a period of about 12 hours of high water tomorrow from midnight on."
Weather experts predict the tidal surge on Monday could be anywhere between eight and 10 feet high. This is bad news for businesses in St. Marks.
Stanley West, a riverside cafe owner, says, "We just mainly shut the thing down which means no income's coming in and we just have to keep our fingers crossed and wait."
Residents in Wakulla and Franklin Counties spent Sunday trying to secure their homes.
Wallace Giddens, a resident, says, "Sandbags I hope will keep the water out of the rooms a little longer. It's just a delaying tactic. It's not certainly nothing waterproof, but just hoping to slow it down."
Boat owners also tried to safeguard their property from the impending tidal surge.
Randy Miller, a Wakulla County boat owner, says, "Come down to lower the tops down and make sure that the ropes would be secure enough to keep the boat in place."
As Katrina hurls massive tidal surges to coastal areas just as Dennis did in July, Wakulla and Franklin Counties have issued mandatory evacuations of those places.
Tidal surges that hit the Big Bend coastline Monday may be as high as they were last month during Hurricane Dennis.
