The New Orleans area remains under a flood threat as heavy rainfall persists, with isolated totals of up to 5 inches already reported. More rain is expected overnight, with drainage systems potentially overwhelmed, causing street flooding and impassable roads in low-lying areas.
A strong cold front is set to sweep through Tuesday, bringing relief from the rain but ushering in a sharp drop in temperatures. By late Wednesday night, areas north of the I-10/12 corridor could see freezing or near-freezing conditions, marking a dramatic shift from the current warm, moist air.
Residents are urged to stay alert for updates and exercise caution around flooded streets, especially underpasses. Prepare for cold weather by midweek as the storm clears out.
