Information on Weather Maps for California Subregions

---

1. Plots of surface weather station reports, including:
   • wind speed (in knots) and wind direction;
   • cloud cover;
   • temperature and dew-point temperature (both in degrees Fahrenheit);
   • sea-level pressure (coded, in millibars); and
   • current weather (represented symbolically, if present); and
2. Weather-radar echoes (showing precipitation intensities, color-coded).

3. A GOES-West visible satellite image.

The geopolitical background for each weather map shows:

• coastlines (gold lines);
• state and national boundaries (thick red lines);
• county boundaries (thin red lines); and
• interstate highways (thick green lines).

The time and date appearing on these maps is in Universal Time Coordinates (UTC), formerly known as Greenwich Mean Time (GMT). (See comments about time labels for more information.)

For information about reading some of the meteorological information on these maps, refer to the key to weather-station plots; and description of information on weather-radar maps and general information about weather radars.
