Actually it got down into the 20s for about 5 days!! For S.Texas that's super cold. Most water pipes froze and many lost power completely. Houses around here aren't built to handle those low temps for many days in a row. You couldn't find a pumber to fix the broken pipes for weeks they were so busy. On top of that there was no PVC piping or copper pipes to make the repairs because the trucks couldn't bring supplies. There was a shortage of all plumbing supplies for about 6/8 weeks. The infrastructure designed to deliver power under normal circumstances collapsed under the extreme cold conditions.
