The background geographical information in this page comes from OpenStreetMap and the usage is subject to OpenStreetMap's License Terms. : Station higher than 500 metres above mean sea level M: Under Maintenance / Data Temporarily Not Available Only limited data validation has been carried out. The lightning information displayed above is provisional. Other factors, including interruption to telecommunications services and power supply, can also affect the reliability and availability of the lightning information. As it takes time for communication and computation, there is normally a delay of a few minutes in the display of data. There will be some low clouds and fog across eastern and southeastern VA this morning.
There is no guarantee that all occurred lightning strokes can be detected and false detection of lightning strokes cannot be ruled out completely. 1 day ago &0183 &32 Posted at 5:17 AM, and last updated 2:17 AM, RICHMOND, Va. The location accuracy and detection efficiency will be reduced when the lightning stroke occurs outside of the network or when not all of the stations are operative. The efficiency of cloud-to-cloud lightning detection is more than 50%. the probability that a stroke with peak current greater than a certain level can be detected by the network, is estimated to reach 95%. The accuracy of the enhanced system in determining the location of cloud-to-ground lightning strokes is about 250 m within the network when all stations are operative. Although the map can be scaled down to show other parts of the world, it will only display lightning location within the vicinity of Hong Kong. Please note that the actual location of the lightning stroke may be more than several hundred metres away from the displayed position. The above map can be zoomed into street level so that the lightning symbol may be displayed over a street or a building. The location as shown depicts roughly the starting point of the discharge from one cloud to the other. Worldwide animated weather map, with easy to use layers and precise spot forecast. However, it should be noted that they may sometimes precede cloud-to-ground strokes. This view provides specific radar products for a selected radar station and storm based alerts. Weather radar, wind and waves forecast for kiters, surfers, paragliders, pilots, sailors and anyone else. As such, they might not affect people or facilities on the ground. Cloud-to-cloud lightning strokes are those detected strokes that did not reach the ground. The lightning records are updated at 5-minute intervals. The image shows cloud-to-ground or cloud-to-cloud lightning strokes as detected by the Lightning Location Network over the Pearl River Estuary and nearby regions in the past 30 minutes.
