Rainfall amounts of 1 to 3 inches (locally up to 4 inches) over already saturated ground will have the potential to produce minor flooding of urban, low-lying, and poor drainage areas. .EXCESSIVE HEAT IMPACT... Very warm temperatures and high humidity will combine to produce peak afternoon heat index values of 102 to 107 degrees with up to 110 degrees across portions of Okeechobee, Saint Lucie and Martin counties. A Heat Advisory is in effect this afternoon for the aforementioned three counties. A Moderate to High Heat Risk exists across all of east central Florida today.
