Other Info

note

Please note that there are forecasts every 3 hours at leads (L) from 0 to 72 hours and forecasts every 6 hours thereafter, out to 192 hours. The values at all the 6-hourly leads that are multiples of 6 (L = 6, 12, 18, etc.) are six-hourly values of the given variable (e.g., for precipitation, accumulations over the previous 6 hours). The values at the remaining 3-hourly leads (L = 3, 9, 15, etc.) are three-hourly values of the given variable (e.g., for precipitation, accumulations over the previous 3 hours).
