eventdescription
val>1forecast/observed value greater than 1 unit of the forecast parameter
an>4forecast/observed anomaly with respect to the station climate mean greater than 4 units of the forecast value
an<-1.5stdforecast/observed anomaly with respect to the station climate mean less than -1.5 times the standard deviation of the climate at the observation station
