18Z model run delayed
Model status ...HAFS MODEL PRODUCTION ISSUE - UPDATE...
The 18Z model run is running late. Products that depend on it — including automated forecasts and the graphics many weather apps use — may show up later than usual.
What the message says: “The 18Z HAFS-A for Hurricane Polo is expected to be about 70 minutes late.”
“18Z” is the run’s start time in UTC. NWS runs its main models four times a day — 00Z, 06Z, 12Z and 18Z — and each run begins by digesting a global snapshot of current conditions taken at that hour.
