St. Louis (KSDK)--A weakening Isaac continues to churn through western Arkansas Friday morning. The storm has winds of 25mph and has been downgraded to a tropical depression.
While the storm will continue to move fairly slowly, a general turn more to the north with an increase in speed will begin by tonight and Saturday.
Remnants of Isaac will bring rain into the Bi-state region today through Sunday. Locally, three to five inches of rain can be expected by the time the rain ends which is expected to be sometime Sunday. Locally higher amounts remain possible.
Since the rainfall is expected to be spread over three days, widespread flooding is not expected. However, flood prone and urban areas may experience some localized flooding.
Yearly rainfall deficits for the region are running between five and 12 inches, which has devastated corn and soybean crops, and led to one of the driest years on record.
In St. Louis, through August 27th, the rain deficit is 5.5 inches.
The rain that is likely to hit the area will be welcomed by most and could make a significant dent in the ongoing drought.
