accumulated rain in mm
- Availability generally reliable but not guaranteed!
- All times in UTC - always check validity timestamp!
- Runtime displayed above images near top of page
- Validity time displayed in image caption
- Validity time is accurate, but H+xx prog offset is assumed based on existence/number of images
- Maps show total accumulated rain since model runtime at H+0
- First image at H+0 never contains rain (no previous period to sum over)
- H+6 also missing rain (since GFS upgrade in Jun 2019), H+12 shows 12 hour accumulation!
- Maps are 6 hourly out to 10 days (H+240)
- Updates 4x/day soon after 05/11/17/23 UTC (ie 5/11 am/pm NZST or 6/12 am/pm NZDT)
