HPE risk in summary

Next 12 and 24 hours rainfall probabilities
Quantiles

Xaxis : date, each column represents a part of the day (6 hours for PEARP , 12 hours for EPS). Yaxis : run date and ensemble member. The Graph is divided into 3 parts, representing the last 3 runs of the ensemble; each line represents an ensemble member. A red box indicates the prediction of an HPE by an ensemble member for the corresponding period. The more red boxes the highest probability of HPE occurrence over the domain. It's an EXPERIMENTAL product, not operational yet.
Xaxis: date, the graph is horizontally divided in time (6 hours for PEARP , 12 hours for EPS) Yaxis: probability constructed by the combination of climatology and the ensemble. The exponent “C” refers to climatology compared to past graphs “a” and “E” refers to the graph “a”. It's an EXPERIMENTAL product, not operational yet.
