Southern Baptist churches in Tennessee were urged to make today a day of prayer for relief from the Southeast's drought. "Farmers are already severely affected economically, and all of us will soon feel the effect," said Dr. James McCluskey, a Knoxville pastor. Agricultural losses from the drought are estimated at more than $2.3 billion. Scattered rain showers last week did little to curb the months-long drought, a hydrologist with the U.S. Geological Survey said. Atlanta got its steadiest rain in weeks Friday, but it was only 0.58 of an inch.
