NASHVILLE — Forecasters expect remnants of Tropical Depression Cindy to drench parts of Tennessee, Kentucky and West Virginia this afternoon and evening, bringing heavy rainfall, possible flash flooding and higher river and lake levels through the weekend.

Flash flood watches were in effect in much of Kentucky and West Virginia. Crews in Memphis, Tennessee, worked Thursday to clear storm drains to help prevent street flooding.

Meanwhile the Gulf Coast is still suffering from the effects of Cindy, a former tropical storm in the Gulf of Mexico that crawled ashore early Thursday near the Louisiana-Texas state line. Downgraded to a tropical depression, Cindy weakened as it crossed Louisiana toward Arkansas but a broad circulation around the system swept moist Gulf air over the South, fueling severe weather and pushing up coastal tides.

The storm forced Carnival to reroute two of its ships. Carnival Valor was rerouted west from Cozumel to Progreso. Carnival Triumph was also rerouted to Progreso but circled back later to stop in Cozumel. The cruise line also made a change to Carnival Vista’s itinerary due to Tropical Storm Bret, passing on a stop at Curacao.
