How frost, heat and wind alerts work
Every three hours AgriIntel checks each farm's forecast for the next 3 days. A daily low at or below 0°C raises a frost alert, a high at or above 32°C a heat alert, and peak wind at or above 50 km/h a wind alert. Alerts appear in the dashboard and are emailed if email is on.

Before you start
- A farm with a weather point. See add a farm.
- An active plan or trial on the account. Alerts are only checked for accounts with one.
- For email: Email notifications and Weather alerts both turned on in Settings. Both are on by default.
The thresholds
| Alert | Raised when | Priority |
|---|---|---|
| Frost risk | Daily low at or below 0°C | Medium |
| Frost warning | Daily low at or below -2°C | High |
| Extreme heat | Daily high at or above 32°C | Medium |
| High wind | Peak forecast wind at or above 50 km/h | Medium |
- Values are rounded to whole degrees and whole km/h before they are compared, so a forecast low of 0.4°C rounds to 0°C and raises a frost alert.
- A day with no wind reading cannot raise a wind alert; missing wind is never counted as calm or as a value.
- These are software thresholds for planning. They are not crop injury thresholds and they cannot be changed per farm, per field or per crop yet.
When checks run and what they look at
- Checks are scheduled every three hours, at 15 minutes past the hour (UTC).
- Each check reads the first 3 days of the farm's forecast, normally today and the next two days, in farm-local dates.
- There is at most one alert per farm, per type, per day. Later checks do not duplicate it, and they do not rewrite it if the forecast changes.
- An alert is marked resolved automatically once its day has ended everywhere in Canada.
Email delivery
- New alerts are sent to your account email from [email protected], combined into one email per check.
- In Settings → Notifications, turning off Email notifications or Weather alerts stops alert emails. Alerts still appear in the dashboard.
- If an email fails, it is retried on later checks for up to 24 hours and 3 attempts.
- If your address bounced permanently or reported an email as spam, AgriIntel stops emailing it and the dashboard shows a notice.
Work with an alert in the dashboard
- The Alerts screen lists alerts in Active, Resolved, Snoozed and All tabs, sorted by priority.
- Each alert's menu offers Acknowledge, Mark Resolved and Snooze for 30 minutes, 1 hour or 24 hours.
- The Weather screen shows the active alerts for the farm you are viewing.
Official weather alerts
AgriIntel alerts are not official warnings. Environment and Climate Change Canada publishes the public colour-coded weather alerts (yellow, orange and red), and those remain the authority for your region. AgriIntel does not include that feed today, so keep watching official alerts as well.
Limits
- Alerts carry forecast uncertainty. A check can miss a change that happens between runs, and an alert can arrive late or not at all if a check or an email fails.
- Alerts are by email and in the dashboard only. There are no SMS or push notifications.
- Alerts use the farm's weather point, not each field, and the thresholds cannot be adjusted.
- No crop-specific advice is given.
