Weekend of rain coming for Nashville as Isaias moves inland

State of play: Most of the rain will be concentrated during Sunday afternoon and evening, with as much as 3 inches of precipitation possible.

Threat level: Nashville and surrounding counties will be under a flood watch from Saturday to Sunday morning. Forecasters warn that excessive runoff could flood creeks, streams, low-lying areas and low water crossings.

• Thunderstorms could develop, and wind gusts could exceed 30 mph. The NWS cited a low chance of "quick spin-up tornadoes."

The big picture: Isaias is expected to strengthen before reaching the northern Gulf Coast late Friday or early Saturday, bringing a more dangerous combination of storm surge, damaging winds and heavy rainfall there.
