AUSTIN (KXAN) — Fire hydrants and pumps froze in Austin’s bitter cold weather, and the Austin Fire Department said it created some big problems while responding to a call.

At 10:26 a.m., AFD responded to a fire on Brodie Lane and had to use a ladder truck with a stream of water to keep the fire from getting to another building. AFD evacuated the building, but since Capital Metro suspended service for Monday, it wasn’t immediately sure where to send people. AFD said it was trying to move them to another building.

Twenty apartment units were displaced the agency said.

Later on Twitter, AFD said it responded to three structure fires on Monday, all related to blazes that originated near a fireplace.
