South Louisiana Residents Say They Heard Port Arthur Explosion

An explosion and fire at Valero’s refinery in Port Arthur, Texas on Monday evening triggered a shelter-in-place for parts of the city, including Port Arthur’s west side, Pleasure Island, and Sabine Pass. Officials said all personnel were accounted for and no injuries had been reported as emergency crews responded and air quality monitoring got underway. State Highways 82 and 87 were also closed as a precaution.

But while the emergency response unfolded in Southeast Texas, the reaction across South Louisiana quickly became a story of its own.

Comments poured in from Lafayette, Broussard, Youngsville, Scott, Milton, Carencro, Breaux Bridge, Maurice, Delcambre, Opelousas, Church Point, Sunset, Kaplan, and even farther north, with people saying they heard a loud boom, felt a rumble under their feet, or thought something had hit their roof or garage door.

One person in Lafayette said it “shook our garage door and felt like something fell on our roof.” Another in Scott said it “sounded like thunder but no clouds.” A commenter in Carencro said it was “VERY loud,” while others in Youngsville, Broussard, Milton, Breaux Bridge, and Delcambre described rattling windows, shaking houses, and a sound that did not feel like normal thunder.

What Officials Have Confirmed

So far, officials in Texas have confirmed the refinery incident, the shelter-in-place, road closures, and air monitoring. Jefferson County Sheriff Zena Stephens said the fire may have involved a heater unit, while Valero said its emergency response team was coordinating with local authorities. Sabine Pass ISD also announced it would be closed Tuesday because of the incident.

What has not been officially confirmed is whether the explosion itself could be heard across such a large stretch of Louisiana.

That has not stopped the speculation online.

Social Media Reacts Across Acadiana

The KTDY Facebook page turned into a roll call of South Louisiana communities checking in after the blast. Some people were convinced the Port Arthur explosion was the source. Others were skeptical, pointing out the distance between Acadiana and Port Arthur.

That split reaction may be what makes this story so compelling for Louisiana readers. The confirmed incident happened in Texas. The unanswered question is whether the boom people heard in Acadiana was actually connected, or whether residents across the region experienced something else at roughly the same time.

Either way, Monday night left plenty of South Louisiana residents with the same reaction: What in the world was that?

This Is Still A Developing Story

Officials continue to monitor the situation in Port Arthur, where fire crews and hazmat teams responded and air monitoring remains part of the emergency response. Authorities have not reported any injuries, and no evacuation order had been issued as of the latest updates.
