Trouble in the Tropics, Rain Ahead in the Forecast
Meteorologist Danielle Banks is tracking two areas to watch in the tropics: Invest 97-E, and another area that could impact the Southern Plains later in the week.
South Carolina's Lowcountry rivers will take days to return to their banks after the recent record-smashing rain event.

Dr. Matt Sitkowski, coordinating weather producer for The Weather Channel, calculated that if 12 inches of rain fell over the entire Palmetto State, that would equate to 6.68 trillion gallons of water. This is about 20,900 gallons of water for every American, or enough to fill the world's largest swimming pool 101,000 times over.
Peak rainfall totals from Carolinas historic rain event through Oct. 5, 2015, along with locations of dam breaches.
Now all that water is draining downstream.
South Carolina's elevation varies. The Blue Ridge Mountains touch South Carolina's far northwest, with elevations up to 3,560 feet.
The state's rolling Midlands, the transition between the relatively more rugged Upstate and the Lowcountry, contributed to the destructive power of the flash floods.
There is only a 272 foot elevation difference between Columbia – the state's capital in the Midlands – and Charleston on the Atlantic coast.
Major rivers draining the South Carolina coastal plain in the area of heaviest rain.
This gentle elevation change from the Midlands to the coast means some rivers will remain in flood for days, and some will be rising as the tremendous volume of water moves downstream into the Lowcountry.
The following forecast graphics are updated regularly by National Weather Service forecast offices. Minor (orange), moderate (red) and major (purple) flood stages are denoted on each graph. Some graphs also have the current or previous record stages labeled, as well.
