Thunderstorms around Ao Nang.

The Boltek lightning detector is designed to detect only lightning strikes; a cloud to cloud lightning will generally not be recorded.
The map shows all lightning strikes the last minute (X) and the last 30 minutes (+).

The direction of the flashes is accurate; the distance is not.
A strong flash will appear to be closer; a weak flash appears to be farther away.

The circle indicates the most probable position of the thunderstorm, obtained by combining both weak and strong flashes.
