Weekly reported cases and deaths and example equally weighted median ensemble forecasts (predictive median and 95% interval) for selected U.S. states. Forecasts were produced each week, but for legibility, only forecasts originating from every sixth week are displayed. Data providers occasionally change initial reports (green lines) leading to revised values (black lines). Vertical dashed lines indicate the start of the prospective ensemble evaluation phase. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
