Overpass closed after showers produce localized flooding
New Orleans police closed Carrollton Avenue at the I‑10 overpass Tuesday after showers pushed into the metro and produced localized street flooding. The closure came as meteorologists monitoring WDSU radar tracked a band of showers and occasional lightning moving from south to north into the city.
Traffic on the Carrollton approach to I‑10 was impacted while crews and public safety officers worked to block traffic at the flooded overpass. The closure underscores how even short bursts of heavy rain this week can interrupt daily commutes and strain low‑lying stretches of roadway across the metro.
Short‑term conditions and the forecast
Forecasters said the area is seeing increasing tropical moisture interacting with a front that will keep the region wetter through Sunday and Monday. The Weather Prediction Center placed the area in a marginal risk for flooding tomorrow and in a slight (level 2 of 4) risk for Monday.

Locally brief but heavy showers were moving into Metairie, LaPlace and other suburbs; some cells produced lightning. Forecasters cautioned that while today’s chance of flooding was described as an isolated possibility, the overall chance for rain increases through the coming days.
"Isolated flooding something we have to consider"
What this means for residents
For New Orleans drivers and neighborhood residents, the closure is a reminder that flash flooding can quickly make major intersections and overpasses impassable. Short‑duration, high‑intensity rain can pond on roadways and overwhelm drains, especially in lower elevations.
- Avoid flooded roadways and do not attempt to drive through standing water.
- Expect additional rain through the weekend with elevated flood risk Monday.
- Follow local alerts and NOPD traffic posts for real‑time closure updates.
Even as the broader tropics remain quiet, forecasters say increasing tropical moisture and an approaching front are the drivers behind the wetter pattern. City commuters should plan for interruptions in the mornings and evenings as rounds of showers move through the metro.
Officials have not released a timeline for reopening the Carrollton Avenue overpass. Motorists should seek alternate routes and monitor local weather and police updates for when the roadway is cleared.
