Heat lightning is a common name for a lightning flash that appears to produce no discernible thunder because it occurs too far away for the thunder to be heard. You don't want to run into either, but positive lightning may be considered more dangerous because its peak electric current is often stronger, the flash duration (continuing) is typically longer, and its peak charge can be much greater than a negative strike. The wind will blow each successive stroke slightly to one side of the previous stroke, causing a ribbon appearance. You are also fairly safe in a vehicle, if the windows are up and you do not touch any metal. The electrical discharge occurs either between two clouds, the ground and the cloud or electrically charged parts of a cloud.
