Early on the morning of June 16th as severe storms crossed over North Texas, crews from TCFD were alerted to a possible structure fire in the NW corner of the city. Having just returned to quarters from a commercial alarm in their first due, E11 crews were first to be enroute and arrived within moments of the first due T13. Companies reported on with heavy fire from the attic of a large 2 story frame and made an aggressive interior attack with selective application of the master stream. Mutual aide companies from Little Elm and Plano arrived and provided relief crews as the fire took the attic and crews were forced to temporarily suspend interior operations. The main body of the fire was knocked down within 25 minutes of initial tones and placed under control shortly after. crews remained into the morning to complete extensive overhaul and salvage operations.
