Joining several surrounding cities and municipal districts, the city of Houston issued a boil water notice Feb. 17 as freezing temperatures and residents dripping taps have caused low water pressure across the region. Harris County Judge Lina Hidalgo added that residents in the region should assume they are under a boil water notice unless they are told otherwise by local leaders.

NEW: You should assume you are under a boil water notice unless you've heard different from your local authorities. Please boil all tap water for 2 minutes after it reaches a full rolling boil.
