The nearby flash rate counter shows the number of
nearby flashes within the last minute.
Nearby flashes are very likely to be no more than a
few miles away. With version 4.6 and later of the
software,
only flashes that exhibit certain
characteristics are logged as nearby flashes. This is a
significant change from older versions when this
counter registered strong flashes. (The Custom
Summary language keywords still refer to these types
of flashes as “strong” flashes rather than “nearby”
flashes.) If you want to reset the record value for this
counter from its previous value, right-click on the
counter and choose Reset record… from the popup
menu.
A red alert on this counter is almost always an
indication that a storm is nearby. It is not necessarily
an indicator that the storm is going to impact your
location, since the storm may be moving away from
you.
