After a few moments of waiting, the fire department finally showed up. Eventually they were able to put the fire out, but not before much of the neighbor's house was destroyed. The heat from the flames did damage to my parents' house and several of the other nearby houses.
Thankfully it seems no one was injured. While my parents' house was damaged, it did not catch fire (which considering how close together the houses are and how strong the wind was, they were very fortunate.) Firefighters went through the house to make sure it was safe. My mom went back today to survey the damages. My sister sent me some pictures. Fortunately the insurance will cover the damage.
We pray that the rebuild process will go smoothly for everyone affected.
