Guam: one station shown in each small area of the map, so it stays legible; the table lists every station in a state.

On the map

  • Observed temperature, °F, above-left of the station
  • Observed dew point, °F, below-left
  • Observed temperature and dew point are left off the map on a screen this narrow: the table below lists every station’s.
  • Observed wind: the staff points to where it blows from; a full barb is 10 kt, a half 5, a pennant 50; a ring is calm
  • Analysis cold front
  • Analysis warm front
  • Analysis stationary front
  • Analysis occluded front
  • Analysis dry line
  • Analysis trough
  • Analysis high and low pressure centres, with their pressure in millibars

WPC’s bulletin does not say which side of a front its symbols go, so this map draws no triangles or half-circles; each front is named on the map and in the list.

Observed 2,245 stations, each at its own time, most between and . Airport and other automated stations’ reports (METARs), as AviationWeather.gov decodes them. Left out: 471 reports flagged by the station for maintenance and one report that cannot be right; no other quality control is applied here.

Analysis WPC’s surface analysis valid , issued . A forecaster’s analysis of the fronts and pressure centres at that hour, every three hours.

WPC analyses no front across Guam; troughs are drawn on the map.

No current station report in Guam.
