What happened
Strong sustained winds and wind gusts, in association with Tropical Storm Lee which made landfall across the south central and southeast Louisiana gulf coast, were felt across all of Northeast Texas on September 4th. These winds, along with very low humidity values and exceptional drought conditions across Northeast Texas, resulted in critical wildfire threat being met across the region. A wildfire, which became known as the Moore Fire, began 4 miles southwest of Gladewater consuming 1556 acres of timberland and grassland near Hwy. 135. Twenty homes were destroyed along with 15 outbuildings. A 20 year old woman and her 18 month old daughter died in a house fire on Lincoln Springs Road off Old Gladewater Road. One man was in the home and escaped with minor burns. One firefighter was injured when a tree fell over on him. The fire was not contained until September 13th.
