QPE = Precipitation Estimate (observed) · QPF = Precipitation Forecast
Upstream rainfall too light to drive a rise
Ground: VERY DRY ground (by pre-storm baseflow 0.1 cfs; about 1.1" of rain soaks in before runoff starts)
No rise indicated by recent rainfall
Soil: DAMP · Confidence: CALIBRATED
Calibrated chance the gauge rises from BELOW_LOW to LOW within the next 12 h, from 6 h rainfall (7.3 mm) at this gauge level (history stratum gq0); ground DAMP by 7-day rain. Experimental.
| Level | Chance | Rain before past rises 6 h total · p25 / p50 / p75 | n | ||
|---|---|---|---|---|---|
| LOW 3 ft | ~0% | 0.35" | 0.47" | 0.66" | 27 damp soil |
| MEDIUM 4 ft | ~0% | fewer than 10 past rises on record | |||
| HIGH 6 ft | ~0% | fewer than 10 past rises on record | |||
Rain columns are context, not a probability: the 6-h rain that fell before past rises to each level (quartiles of n past rises; the population is noted under n). This basin: 0.29" so far in the last 6 h. The Chance column is the calibrated forecast.
