A tropical disturbance moving along Mexico’s eastern coastline is showing increasing signs of development as it drifts toward the western Gulf of Mexico.

The storm was moving to the northeast at 9 mph along the Gulf coast.

A tropical disturbance in the western Gulf will contribute to the risk for heavy rain and numerous flash floods across the South this week.

Forecasters say Arthur could generate life-threatening flash floods along the northern Gulf Coast. But it is not expected to strengthen further.
