Wind chills as low as seven degrees below zero are possible, with the coldest ones in the Hill Country and Austin metro area. Cold wind chills can result in hypothermia if precautions are not taken. Avoid outside activities if possible. When outdoors wear clothing, a hat and gloves.
Gusty winds could blow around unsecured objects. Tree limbs could be blown down, possibly resulting in a few power outages. Frost and freeze conditions will kill crops, and other sensitive vegetation and possibly damage unprotected outdoor plumbing.
Use extra caution when driving, especially if driving a high-profile vehicle.
To prevent freezing and possible bursting of outdoor water pipes they should be wrapped, drained or allowed to drip slowly. Drain in-ground water systems and cover above-ground pipes to protect them from freezing.
Keep pets warm and dry and indoors if possible. Limit time outside and bundle them up. Provide plenty of food and water. Dehydration is especially dangerous in winter. Thoroughly clean paws when bringing them in.
The pollen count for mountain cedar could rise considerably on Friday due to high winds.
