Use the score as a filter, not an all-clear.Official warnings, local closures, surf conditions and access rules always take priority.
Why separate alerts from the score?
An alert is an official product, not just another weighted input. CoastEventRadar keeps it visible as its own layer so a high “interesting conditions” score can never hide a High Surf, Coastal Flood, Rip Current or other active warning product.
