Current Observation MapsEach arrow on the observation map represents an actual weather station. If you move your mouse over one of the arrows, the latest weather report from that station will be displayed to the right of the map, along with a 2 day forecast.
In addition to wind maps, XCWeather also provides maps of the current temperature, weather conditions, visibility and pressure. To change the map type use the tabs at the top of the map. Each map is colour-coded and a key is displayed at the bottom left of the screen.
Detailed ForecastFor a more detailed seven day forecast you can enter a location or postcode in the text field at the top right of the screen and click the Get Forecast button.
In addition to the usual information, this forecast also includes the expected total precipitation in millimeters over the next 3 hours, the total cloud cover as a percentage, the visibility in meters and the mean sea level pressure (red for high values, blue for low).
XCWeather can generate forecasts for towns and postcodes across most of the continent or you can specify a grid reference in decimal degrees for locations away from towns or over the sea (e.g. 52.67,-2.19)

PreferencesOnce you've got the basics, make yourself at home by using the 'Preference' button to set your default location, wind speed units and many other options.
Red Arrows and Gusting WindRed arrows show that the wind is gusting. The wind is said to be gusting if the maximum speed is 10 knots or more above the current average speed. The size of each arrow on the map is always based on the average wind speed.
Grey arrows indicate that a stations observation hasn't updated and that it's about to be removed from the map.
Wind ScaleThe colours used to display wind strength are based on the Beaufort scale with each colour representing a different force on a range of 1 to 11+. Wind speed can be displayed in several different units based on your preference settings, the images below show the MPH and Knots scales.
The wind direction is defined as the direction from which the wind originates. This means that an arrow that points from north to south indicates a northerly wind (a wind that comes from the north).
Temperatures below 0°C are shown in blue.
Forecast RainOn the detailed forecast, the amount of rain is given as the total water expected to fall over the next three hours. Be aware that the same quantity may arrive as a short sharp shower or a much longer period of lighter rain.
Rainfall and hail are given in millimeters of water against a blue background:
If snow is forecast the rain column will change to a pink background and display the expected snowfall in centimeters:
This is an estimate as the actual depth may vary according to the type of snow that falls.
Fog and Mist
For the forecast, Fog is defined as a visibility of below 1000 meters and Mist as a visibility of between 1000 and 5000 meters.
