The U.S. National Ice Center (USNIC) monitors and records ice conditions within the Mid-Atlantic coastal region. A main area of recurring seasonal ice (may have years of no ice) is the Chesapeake, Potomac and Delaware Bay region. When ice is present, USNIC produces an ice chart, weekly outlook and associated support files.
A periodic ice chart that displays ice conditions based off the Mid Atlantic analysis. An ice chart is produced when suitable satellite coverage over the region and/or reliable observations are reported. Ice coverage is detailed by color coded ice concentrations.
