Lightning Chart Information:

These charts show the number of (cloud-to-ground) lightning strikes in the selected region. Lightning strikes are a unique method to track the monsoon as the data do not suffer from issues more common to rain gauges (low spatial coverage across the region outside of population centers) and can therefore give a more complete picture of thunderstorm activity. The bar chart displays total strikes to date for each year, as well as the total for the entire season ending September 30th. The charts are updated around 5pm daily. Data source: VAISALA NLDN.
