When the family reached the third floor, they were hit with a blast of heat and smoke.
They were met by a blast of smoke and heat coming from the lobby.
I screwed up my eyes as the main blast of heat hit me.
A blast of heat greeted them as the door was opened.
The three friends felt a blast of heat from the explosion.
A blast of heat hit them as she opened the door.
Then felt a blast of heat and saw red through his eyelids.
A blast of heat came to me, but this was memory.
Then the light and the blast of searing heat were gone.
They headed out the door, to be met by a blast of heat, light, and noise.
