The Snow Water Equivalent of any snow on the ground.
Snow water equivalent is the water in the snowpack that will be released when the snow melts.
Snow depth if/when snow is on the ground.

For a national perspective on snow, data is available from the National Operational Hydrologic Remote Sensing Center (NOHRSC) where the National Snow Analysis and an Interactive Snow Map are available.
Note: If there are areas in yellow, then these areas are experiencing abnormally dry, but not quite drought, conditions. See below for additional drought related links.

The water resources and supplies outlook is good for the Mid-Atlantic Region.
Winter has arrived. This typically means that our weather systems will bring snow and rain (as well as ice from time to time) depending upon temperatures relative to freezing. A snow pack typically develops in northern areas and in the mountains but a snow/melt cycle occurs further south. Autumn left us with some wetter than normal areas as well as some dryer than normal areas (especially in Virginia). But, no especially wet nor dry areas were dominant in the Mid-Atlantic. There are no strong indicators of a wet winter. Though possible any time of year, the flood threat is usually lower during this time of year. So, in the absence of a wet pattern developing, any flood threat is "normal" while the threat for drought is quite low.
