72-hour Forecast Precipitable Water

WorldWinds has generated an hourly forecast TPW product using the GFS model. Interest in a forecast TPW field was expressed by Beta Test users to better help predict where pockets of moisture are expected to travel. The product is a 72 hour forecast, at hourly increments that will be updated 4 times a day as new GFS (00, 06, 12, and 18 UTC) data becomes available. This will aid in forecasting high rainfall events in conjunction with the observed bTPW analysis.
