How do Almanac fishing alerts work?

Almanac fishing alerts are optional email digests for signed-in anglers that fire when watched or nearby rivers are fishable or coming into shape — using forecast and live recommendation scores, optional drive-radius filters, storm banners when the user's own region buckets are active, and frequency settings such as daily or only on conditions change. An alert on Almanac is a personalized "worth looking" message, not a severe-weather emergency wire. NWS watches and warnings still inform the storm stack. Angler alerts translate Almanac's fishability and forecast engines into inbox timing. An alert can fire when rivers on the user's watch list or favorites score as fishable against their threshold, when rivers are coming into shape on the forecast trajectory, or in conditions-change mode only when rivers enter or leave the optimal or fishable set. Storm-aware personal forecast subjects and banners appear when an active storm bucket intersects the user's drive radius, using blowout versus reopening language. Seasonal and run-state tips — fall run starting, holdover, a summer smallmouth pivot, and similar — can ride along. The primary channel is email. Preferences control rivers, frequency, channels, and home location for drive-time filtering. Calls to action point back to the personal forecast and the public Index forecast, so the email is a pointer rather than a dead end. Alerts stay quiet when nothing in the user's radius changed, especially in conditions-change mode, so a message means the fishing picture moved.
