*Values in “Departure from Average” show the difference between observed ACE and average values (positive = higher than average; negative = lower than average).
Statements in parentheses show how observed ACE compares to past seasons:
- “Well Above Median” – > 90th Percentile
- “Above Median” – 75th to 90th Percentile
- “Slightly Above Median” – 60th to 75th Percentile
- “Near Normal” – 40th to 60th Percentile
- “Slightly Below Median” – 25th to 40th Percentile
- “Below Median” – 10th to 25th Percentile
- “Well Below Median” – < 10th Percentile
