GRAPHICAL WEATHER (OPTIONAL) (Cont)
New images are available according to the schedule listed below:
The Zulu (Z) forecast times refer to that time in the future for weather forecasts. Therefore, if the current time is 15Z, an
18Z is for 18Z today and a 12Z forecast is for 12Z tomorrow. The hr forecast times refer to the number of hours since the
last model run for weather forecasts. The model runs are completed at 0Z and 12Z each day. Therefore, if the current time
is 15Z, a 30 hr forecast is for 18Z tomorrow (i.e. 30 hour from the last model run, which is 12Z today).
