Torrential downpours that can trigger dangerous flooding is the main threat from a tropical rainstorm along the north-central Gulf coast for the balance of this week. Southern Louisiana is in the crosshairs.

A low pressure system near Florida has a 40% chance of developing into at least a tropical depression, according to the National Hurricane Center.

There’s growing concern for another significant rain and flooding event this week, this time along the Gulf Coast, from what could become the Atlantic basin’s next tropical system.
