Figure 1 - Figure 2 shows the EFAS headline score, the Continuous Ranked Probability Skill Score (CRPSS) for lead times 3, 5 and 10 days for the April to May period across the EFAS domain for catchments larger than 2000km2. The scores are still for the old domain. The scores for the new domain will be presented starting with the next Bulletin. The reference score is the persistence forecast. A CRPSS of 1 indicates perfect skill, 0 indicates that the performance is equal to that of the reference, and any value <0 (shown in red on the maps) indicates the skill is worse than persistence.
