Snowfall is rare in Sacramento, which is only above sea level. In the downtown area, only three significant snow accumulations have occurred since 1900, the last one being in 1976. During especially cold winter and spring storms, intense showers do occasionally produce a significant amount of hail, which can create hazardous driving conditions. Snowfall in the city often melts upon ground contact, with traceable amounts occurring in some years. Significant annual snow accumulations occur in the foothills east of the city, which had brief and traceable amounts of snowfall in January 2002, December 2009, and February 2011. The greatest snowfall ever recorded in Sacramento was on January 5, 1888.
