The National Weather Service revises an active warning constantly — a tornado threat goes from radar-indicated to observed, hail grows from 1" to 1.75", an expiration gets pushed back. Until now those revisions either passed silently or arrived as a repeat of the original alert. Now every update spells out exactly what changed: "Tornado threat now Observed; Hail 1.00" → 1.75"; Warning extended to 4:45 PM CDT." You'll see it on the alert page, in the history timeline and CSV export, and in the text, email, and Slack update itself.

To keep the signal clean, you control how often updates reach you, per rule: Escalations only (the default) notifies you when a warning gets more dangerous, All updates sends every change, and Off stays quiet until the all-clear. Times are shown in the warning's own local zone, and routine continuations that don't materially change anything no longer ping you at all.

When a storm sweeps across your portfolio, you used to get a separate text for every location in its path. Now we group them: a single message listing all affected properties, so a fast-moving severe thunderstorm warning reads as one clear update instead of a buzzing pocket. Alerts that require acknowledgment still arrive individually, so a reply always refers to exactly one location.

Not every alert needs to wake you up. With quiet hours, overnight notifications are held and rolled into a single digest delivered when your morning starts. The digest includes a shareable summary page, so you can forward what happened overnight to anyone — no login required. You can also choose to let critical warnings — like tornado, flash flood, and severe thunderstorm — break through quiet hours, so the alerts that matter most still reach you right away.

You can now get LMKwhen alerts delivered straight to a Slack channel. Connect your workspace, pick a channel, and alerts arrive as rich messages with the location, hazard, and timing at a glance — and your team can acknowledge an alert without leaving Slack. It's the easiest way to put severe weather in front of the whole team at once. Set it up under Notification Channels in your settings.

Managing dozens or hundreds of properties? Upload a CSV and we'll add every address in one pass, ready to attach to alert rules immediately. What used to be an afternoon of data entry is now a single upload.

Setting up the right alerts is now a guided, three-path process. Choose official watches and warnings, severe weather outlooks for advance planning, or forecast thresholds like temperature and wind — and the wizard walks you through which locations and channels each rule covers. You get precise alerting without needing to know how weather products work behind the scenes.

You can now download your complete alert history as a spreadsheet — every alert, location, hazard, and timestamp. Useful for compliance documentation, insurance claims, or simply reviewing how a season treated your properties.
