A former tropical disturbance failed to form into a tropical depression before reaching the coast, but it could still have serious impacts.

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.

The disturbance dubbed Invest 93L washed ashore over Louisiana on Thursday, bringing widespread rainfall of 2 to 5 inches across much of southern Louisiana, with localized totals reaching double digits in the bayous of the Atchafalaya River basin north of Morgan City in coastal south-central Louisiana.
