PredictWind's lightning feature provides the most comprehensive and accurate lightning network worldwide. Real-time updates include new lightning strikes every five minutes. Lightning coverage includes sensors in over one hundred countries, remote areas, oceans and polar regions with precision near 100m. The sophisticated algorithms and machine learning models which process the sensor data offer world-leading location and lightning classification accuracy with filtering to maintain a low false alarm rate.
Tracking lightning is essential for safety and protecting equipment on land or at sea. Lightning strikes can cause injury, fires, and equipment damage, disrupting critical systems like navigation and communication on boats and damaging structures or electronics on land. Monitoring lightning enables you to make informed decisions, such as finding shelter or adjusting your route, to avoid high-risk areas. Staying aware of lightning risks helps you protect yourself, your gear, and your journey, wherever you are.
Lighting strikes can be viewed using the timeline on the map for up to the last hour, appearing and fading in opacity on the map over ten minutes.

Additional meteorological data about Lightning
Lightning strike details include the time, location and the following:
Type of Lightning
Cloud to Cloud - A type of lightning that occurs between different clouds or within separate parts of the same cloud.
Cloud to Ground - A type of lightning that occurs when an electrical discharge travels from a cloud to the Earth’s surface. Cloud to ground is the most well-known and visually dramatic form of lightning.
Amplitude
The amplitude of lightning is measured by its peak current (amps), which can vary widely depending on the type and intensity of the strike. Lightning is displayed on the map in kiloamperes (kA), where 1 kA equals 1,000 amperes and can carry either a positive or negative charge.
Negative Lightning
Negative lighting is the most common type and the primary form of thunderstorm activity, making up about 90-95% of all strikes. Negative lightning transfers negative charges from the cloud to the ground or from within the lower regions of a thundercloud to the upper part.
Negative Cloud-to-Ground Lightning: This is the most common type of lightning. Negative cloud-to-ground strikes generally have a lower peak current than positive ones, making them less intense but more frequent.
Negative Cloud-to-Cloud Lightning: Transfers negative charges between different clouds or within separate parts of the same cloud. It is less intense than cloud-to-ground lightning, with the electrical discharge moving horizontally in the sky rather than reaching the Earth.
Positive Lightning
Positive lightning is less common (5-10% of strikes) but much more powerful. It occurs when positive charges from the upper parts of a thundercloud travel to the negatively charged ground or cloud areas. These strikes often carry currents up to ten times higher than negative lightning and last longer, causing more significant damage.
Positive lightning is typically associated with severe weather, especially near the end of a storm, and is more common in winter storms. Its longer duration increases the risk of wildfires due to its ability to ignite dry vegetation.
Positive Cloud-to-Ground Lightning: Positive cloud-to-ground lightning strikes are less frequent but significantly more intense, often with higher peak currents that make them more damaging and dangerous.
Positive Cloud-to-Cloud Lightning: Similar to negative cloud-to-cloud lightning, this type transfers positive charges between different clouds or within parts of the same cloud. Positive cloud-to-cloud lightning is relatively rare and often involves stronger discharges than the negative form, contributing to brighter flashes in the sky.
