Storm Attributes show information about the severity of storms. This information is recorded by NEXRAD sites wherever there is heavy precipitation. Storm attributes include the direction and speed of the storm over time, as well as the elevation of the top of the storm. Measured in 100s of feet, this value indicates the height of rain within the storm. The higher the values, the more intense a thunderstorm is likely to be. Additional information can be displayed: mesocyclonic activity (MESO) - a strong wind vortex, tornado activity (TVS), and the presence or possibility of hail. This feature is available over the Continental United States.

This color-coded image shows a complete view of any precipitation across North America, including the type and severity. Rain is shown as light green, dark green, yellow, orange and red as intensity increases. Hail, freezing rain and snow are represented with colors from bright pink to blue. The images are displayed as pixels on screen and the resolution of this feature is 2 km per pixel. Coverage includes the Continental US, Canada, and portions of Mexico/Caribbean.

The Lightning feature contains the latitude and longitude of each cloud-to-ground and cloud-to-cloud lightning strike detected in the five minutes prior to the time stamp displayed on the screen. It uses the National Lightning Detection Network (NLDN), the official lightning detection for the U.S. National Weather Service - the most accurate and reliable large-scale lightning detection network in the world.

Alerts can be set to appear and display warnings for weather changes in a selected area helping to provide advance warnings of changing weather conditions.

Weather watch boxes can be set to appear when weather in a selected area is changing.

This is a 5-day overview of the weather based on the closest major metropolitan area to the selected location.

Offshore surface Winds provides a graphical model of surface wind conditions 24NM from shore and beyond. The display is either an arrow showing the wind's direction, or a 'wind barb' to reflect direction and speed. The display can be set to show the current/most recent conditions, or to show the forecast up to 48 hours ahead.

This High-Res wind feature displays surface wind conditions inland and up to 24NM from shore. The display is either an arrow showing the wind's direction, or a 'wind barb' to reflect direction and speed. The display can be set to show the current/most recent conditions, or to show the forecast up to 24 hours ahead.

The Weather Map displays high ('H') and low ('L') pressure systems. Pressure is measured at the center of the system in millibars. The map also indicates cold and warm fronts, the front's direction of movement, Pressure Centers (High and Low Pressure), and Isobars (lines of equal pressure). It can be set to show the current conditions, or to show the forecast up to 48 hours ahead.

High-Res Wave information displays forecasts of the height in 0, 6, 12, 18, and 24-hour increments - up to 24NM from shore. Colors range from blue to green to yellow to red depending on the wave's height. Dark blue denotes waves 1 ft. or less. Red indicates waves 20 ft. or higher. This forecast is available for the Atlantic and Pacific oceans.

Great Lakes Waves displays forecasts of the height, period (time between swells), and direction of waves in the Great Lakes in 0, 6, 12, 18, and 24-hour increments. Colors range from blue to green to yellow to red depending on the wave's height. Dark blue denotes waves 1 ft. or less. Red indicates waves 20 ft. or taller. The Wave Period is provided numerically in seconds. An arrow shows the direction the swells are moving.

Marine warnings are displayed for designated marine zones. Select a particular zone to receive hazardous weather warnings for that region.
