TALLAHASSEE, Fla. (WTXL) — You've probably heard about the tropical moisture heading toward Florida from friends, social media, or on TV.

'Tropical' and 'moisture' are two words that will get Floridian's attention this time of the year.

A very deep, rich plume of moisture will fill in across the peninsula this week, but it's not from the formation of a tropical storm.

This tropical plume originates in the Caribbean, funneling moisture over an area of the peninsula this week.

Rain will fall over a section of Central and South Florida for several days. This is also known as 'training'. Think of Central and South Florida as a track for this moisture plume. Rain falls along the track steadily over several days.

A boundary to the north keeps moisture from traveling too far above Central Florida.

Moisture will be wrapping around a high in the Atlantic and rain is held, just at, or slightly south of the Big Bend by a stationary front.

Deep moisture means excess moisture in the atmosphere. A lot of rain can fall over the next few days from Tampa to the Keys.

Here are some of the expected totals.

Flooding concerns will increase across these areas as moisture falls at a steady to fast rate\.

Even though this area remains in a drought, the ground will have no where for the rain to go once the ground gets saturated.
Extra water will flow into creeks, streams, rivers, and low lying areas increasing flooding concerns.
