Welcome to the Voluntary Observing Ship data entry page.
Thank you for taking the time to submit your observation. The data you
enter here plays a major important role in producing accurate weather and
wave forecasts. Your observation is included in the computer models that
create weather and wind forecasts. The more initial data in the model,
the better the forecast; especially over the data sparse open waters of
the Great Lakes.
If you need to make a correction to your observation,
click on the back button after you transmitted your observation and make
the final correction and retransmit your observation.
Your ship's radio callsign (which is also your login ID here) must be
registered with DMAWDS in order to send an observation.
