>> sandra: massive explosion, injuring at least three workers there. at near the louisiana border. residents with an a half of a mile work evacuated. joining us live from the facility. >> good morning, sandra. the one thing i can tell you is that the fire is still burning. however, not nearly as bad as i was earlier. it seems to be simmering down. you can somewhat see that it is very toxic. going to the southernmost edge of port neches. about 15 to 20 miles per hour. people who lived in that area where the smoke is actually blowing, they are effective. what we are seeing gives us hope in relation to the fire and when it could be completely evacuated. evaporated, if you will.
