St. John the Baptist Parish public schools will be closed Thursday because of water pressure issues, Supt. Kevin George said.

The arctic blast that's settled in south Louisiana has caused problems with running water in several areas, including Baton Rouge, New Orleans and Lafayette.

With customers dripping water in homes and businesses to prevent pipes from freezing, demand has increased and put a strain on resources in some cases. Some areas have implemented boil-water advisories. Others have asked customers to stop dripping water while temperatures are above freezing.
