The remnants of Tropical Storm Arthur, now downgraded to a low-pressure area along the upper Texas coast, are poised to unleash life-threatening flooding and days of heavy rainfall across a significant portion of the southeastern United States.

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

A tropical storm watch has been issued for portions of the Texas and Louisiana coasts for a system that could soon become a short-lived tropical storm.
