Wind Forecast (WINDcast) Map
The WINDcast map shows the forecast wind speed and direction for the next 24 hours. This map shows wind information at the national and regional levels. Wind direction is determined by the direction from which it originates. For example, a northerly wind blows from the north to the south.

Jet Stream Map
The Jet Stream map shows today's high wind speed levels and jetstream directions. Jet streams are fast flowing, relatively narrow air currents found in the atmosphere around 10 kilometers above the surface of the Earth. Winds are commonly classified by their spatial scale, their speed, the types of forces that cause them, the geographic regions in which they occur, or their effect.

Wind is the flow of air or other gases that compose an atmosphere (including, but not limited to, the Earth's). It occurs as air is heated by the Sun and thus rises. Cool air then rushes to occupy the area from which the hot air has just moved. It could be loosely classed as a convection current. Winds are commonly classified by their spatial scale, their speed, the types of forces that cause them, the geographic regions in which they occur, and their effect. In human civilization, wind has inspired mythology, changed the course of history, expanded the range of transport and warfare, and provided a power source for mechanical work, electricity, and recreation.
