NOHRSC footprint times are metadata; pixel analysis time is not independently verified. Snow-depth pixels have previously differed from the footprint time. This is modeled/assimilated snow analysis, not a measurement at a place. Unshaded and no-data areas do not establish zero snow.

    NWS gauge impact statements
    • 7 ft: Severe flooding will cause extensive inundation and flooding of numerous roads and buildings resulting in a significant threat to property and life. Water will be 2 to 3 feet or more above ground level in some areas. Severe flooding will extend inland from the waterfront and shoreline flooding homes, businesses and isolating some neighborhoods. Numerous roads will be impassable under several feet of water and cars submerged. Some areas will need to be evacuated.
    • 6 ft: Widespread flooding of vulnerable areas will result in an elevated threat of property damage to homes and businesses near the waterfront and shoreline. Water will be 1 to 2 feet above ground level in some areas resulting in a sufficient depth to close numerous roads and threaten homes and businesses. Flooding will extend inland from the waterfront along tidal rivers and bays resulting in some road closures and flooding of vehicles.
    • 5 ft: Shallow flooding is expected in the most vulnerable locations near the waterfront and shoreline resulting in a low threat of property damage. Expect up to one foot of water above ground level in low lying, vulnerable areas. Some roads and low lying property including parking lots, parks and lawns near the waterfront will experience shallow flooding.

    Capture times, quality and provenance

    Each report keeps its observation time, first capture of this version, and the SHA-256 of the source bulk body. Corrections at the same observation time replace that point and are marked; unrelated bulk-file changes do not freshen a report.

      Only observed gauge records enter this history. Forecast maxima and forecast hydrograph points never become observations. A missing datum or unsupported flow value remains unknown.
