Priority

Every alert rule has a priority: either Normal or High. Channels can use this flag to filter what they receive — for example, sending only High-priority alerts to SMS while keeping email open for everything.

Priority is available on every plan.

Smart defaults​

When you create a rule, LMKwhen picks a starting priority based on the events you've selected:

  • High — Tornado Warning, Severe Thunderstorm Warning, Flash Flood Warning, Hurricane Warning, Tropical Storm Warning, Blizzard Warning, Ice Storm Warning
  • High — SPC convective categorical at Enhanced or higher, or fire weather categorical at Critical or higher
  • Normal — everything else

You can override the default at the Delivery Options step of the rule wizard. Once you change it, future edits to the rule keep your choice.

The "High priority only" channel filter​

Each notification channel has a priority filter:

  • All alerts (default) — channel receives every alert
  • High priority only — channel skips Normal-priority alerts

Set this in Settings → Notifications under each channel's preferences.

Example​

Say your phone is set to High priority only and your email channel is set to All alerts.

  • A Tornado Warning fires (priority: High) → both your phone and your email receive it.
  • A Wind Advisory fires (priority: Normal) → only email receives it. Your phone stays quiet.

This lets you keep paging-style alerts focused on the things that genuinely need your attention right now, while still seeing the full picture in your inbox.
