MANATEE -- The National Weather Service has issued a river flood warning for the Manatee River near Myakka Head.
The warning will be in effect from Tuesday evening until Friday morning, the Weather Service said.
Forecasters were calling for "minor flooding."
Flood stage at Myakka Head is 11 feet, and as of Monday evening the river was at 5.7 feet.

Waters were expected to rise as more rain falls this week.
"The river is forecast to rise above flood stage by (Tuesday) evening and continue to rise to near 13.5 feet by Wednesday morning. The river is expected to fall below flood stage by early Friday morning," the Weather Service said.
The river last crested at 13.5 feet on Oct. 13, 1998, according to the Weather Service.
At 11 feet, a private road and bridge one mile downstream and surrounding farmland will flood, the Weather Service said.
Tuesday afternoon, Florida Highway Patrol reported that westbound State Road 64 was closed in Myakka City just west of Bear Bay Road because of high water.
Similar river flood warnings were also issued for the Little Manatee River at Wimauma and the Myakka River at Myakka River State Park.
Meanwhile, the rest of Manatee River and the entire Tampa Bay region remain under a flood watch through Wednesday evening.
Already this week, 4 to 6 inches of rain have fallen in some areas, and an additional 3 to 5 inches is expected through Wednesday, according to the Weather Service.
A flood watch means flooding is possible within the next 24 to 36 hours.
