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 is no guarantee that all occurred lightning strokes can be detected and false detection of lightning strokes cannot be ruled out completely. 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. Youll find animated books about lightning, safety tips for all kinds of situations, games for kids and resources for teachers.

This website will teach you how to stay safe and offer insight into the science of lightning. The efficiency of cloud-to-cloud lightning detection is more than 50%. Lightning kills about 20 people in the United States each year, and hundreds more are severely injured. 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. Left-clicking on the 'Speed' area will slow the loop and right-clicking will accelerate the loop, ranging from 0.05 to 5 second interval. Clicking on the map will start/stop the loop. However, it should be noted that they may sometimes precede cloud-to-ground strokes. When both the flight category and weather are displayed, the flight category icon will be on the inside and the partially-transparent weather color on the outside. 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.
