NOTES:

  1. Real-time data are unchecked and preliminary. Please read this disclaimer.
  2. MSL = measurement referenced to Mean Sea Level. Seasonal and weather system biases highly affect estuarine water levels, therefore the MSL datum for this station is preliminary until data are collected over a sufficient length of time to define it accurately.
  3. NGVD29 = measurement referenced to National Geodetic Vertical Datum of 1929.
  4. Daily precipitation resets at solar midnight (midnight EST, 11:00pm EDT). Heated gauge converts frozen preciptation to liquid equivalent.
