Joggers run down a street empty of cars Thursday, Feb. 18, 2021, in Nolensville, Tenn. A second winter storm in a week is bringing more snow to much of Tennessee.
A rural hospital in Anahuac, Texas, about 50 miles (80 kilometers) east of Houston, lost both water and power.
Memphis, Light, Gas & Water issued a boil-water advisory on Thursday out of concern that low water pressure caused by problems at aging pumping stations and water main ruptures could lead to contamination.
That hospital has a water purification system for dialysis and has water reserves for tasks such as cooking and bathing patients, he said.
Methodist Le Bonheur Healthcare also reported problems at some of its Memphis-area facilities due to water pressure problems and the boil advisory.
