St. Johns To Rise, Flood After Storm: "When Hurricane Frances eventually blows out of Central Florida, its torrential rains will already be causing flooding in many communities. But for others, especially neighborhoods along the banks of the St. Johns River, the floodwaters may not arrive for days.

"From its headwaters in Indian River County, north through Brevard and Orange and Seminole and beyond, the slow-moving St. Johns will fill up over the next several days as tributaries swollen from Frances' rains flow into it."

"That means places such as the Seminole County communities of Geneva and Sanford can expect to see rising river levels for days after Frances, said Peggy Glitto, a meteorologist with the National Weather Service."
