Emergency responders monitored a series of powerful explosions involving fuel barges with liquified natural gas on The Mobile River.
The initial blast happened around 8:30 Thursday night, and could be felt as far away as Bay Minette.
Tall flames lit up the night with an orange glow. Fire and multiple explosions on two fuel barges critically injured three people.
Authorities set up a one mile safety zone around the area, blocking roads. They also evacuated the Carnival Cruise Ship Triumph. Austal employees were sent home, and BAE employees told to shelter in place.
Mobile Fire Rescue crews have been keeping a close eye on the burning barges, being very cautious not to approach the scene too soon.
