Forecasters are looking at a weather system off the Mexican coast just south of Texas that they say has a one-in-five chance of developing into something tropical in the next five days.

Dennis Feltgen, a meteorologist at the National Hurricane Center, says if it does develop, it would do so slowly and that it shouldn’t be seen as an imminent threat. He says it wouldn’t necessarily hit Harvey-flooded areas, but there’s a chance.

The system is so far out that forecasters can’t say how much more rain it would bring.

Hurricane Harvey has weakened to a minimal tropical storm, with maximum sustained winds of 40 mph (64 kph), down from 45 mph (72 kph). Warnings and watches have been dropped for nearly all of Texas, except Sabine Pass.
