Winter hikes:

Winter hikes are more dependant on the weather than during the rest of the year. If driving conditions are unsafe on the morning of a hike, or are predicted to be unsafe before we return, the hike will be cancelled.
Deep snow on the trails will also cause cancellation, although it is not always possible to determine what the trail conditions are in advance. If there is a possibility of snow on the trails, you must have hiking boots.
You should always bring an extra pair of socks, as well as the usual things for cold weather; hat, gloves, etc. Wearing cotton clothing, particularly jeans, is not recommended, since cotton takes forever to dry and does not retain warmth when wet.
If the weather is uncertain, you may call the hike leader on the morning of a hike, no earlier than 90 minutes before departure.
