<p>Live radar from F5Weather</a></div>

Our radar is based off of US NEXRAD and Canadian weather radar sites through the quality controlled MRMS system. It compiles various sources for radar data and filters out erroneous returns such as sun spikes and ground clutter. We then colorize the precipitation based on our methods for determining precipitation type. Rain is in shades of green, mixed precipitation and freezing rain in shades of pink and snow is in shades of blue.

Current surface weather map around Rockingham County, VA

This surface map is from the HRRR computer model. It is a 1-hour forecast, updated hourly, which is a good estimate of the current surface conditions. This map shows the current high and low pressure centers, pressure isobar contours, wind streamlines and thickness contours. It also shows the currently depicted preciptiation estimates, although this should not be a substitute for actual live radar. The purple dashed contour is the 5400m thickness line, which is often a good proxy for the rain/snow line.

<p>Hurricane Tracking from F5Weather</a></div>

Our hurricane tracking map monitors for any current or forecast tropical disturbances in the Atlantic. (See our Pacific Hurricane Tracker) Various hurricane models will draw a 'spaghetti plot' in the Atlantic Basin when a disturbance is forecast or exists, showing the system's forecast track. Once a storm has developed, the National Hurricane Center will forecast their official track. This will show up on the map along with the storm's current intensity, track and name. We will also plot some of the storm's vitals and of course the spaghetti plots from the models along with the NHC forecast track will give you an idea of where it's heading, and its forecast intensity with time.
