A front moving through Arkansas is expected to bring continued, and increased, rainfall throughout Tuesday and into the night time hours, the National Weather Service said.
Meteorologist John Robinson said severe storms are unlikely, but thunder is possible.
The largest amounts of rainfall are expected between Tuesday and Wednesday, but a weak upper level system, behind the front currently moving through Arkansas, will bring more rain chances Wednesday night and into Thursday.
The southeastern half of the state is expected to be affected the most by the system, Robinson said.
Rainfall totals are expected to reach 3 to 4 inches in some areas.
A flash flood watch is currently has been issued for southwest Arkansas, and parts of northeast Texas and northwest Louisiana.
