Get warned before frost hits your most vulnerable blocks
Every night during bloom and bud break, WebRun checks the overnight low temperature forecast on AccuWeather for your orchard's location, cross references it against each block's current bud or bloom stage and frost sensitivity threshold in Croptracker, and messages your crew lead on WhatsApp the moment a block is at risk, with the time the temperature is expected to drop.

How do I get warned before frost damages my most vulnerable orchard blocks?
WebRun checks tonight's overnight low forecast on AccuWeather and compares it against each block's current bud stage and frost threshold in Croptracker. The moment a block is at risk, it messages your crew lead on WhatsApp with the blocks affected and the expected coldest hour, giving time to start frost protection before damage occurs.
- Crew leads get a frost warning hours before the coldest point of the night
- Risk is judged against the block's actual bud stage, not a flat temperature rule
- A changed forecast triggers a same night follow up instead of a stale warning
Built for tree fruit growers · orchard crew leads · vineyard and orchard managers · frost protection coordinators

Questions, answered
How does it know which blocks are frost sensitive tonight?
It reads each block's current bud or bloom stage from Croptracker and compares the forecast low against that stage's frost sensitivity threshold, since a block in full bloom can be damaged at a much higher temperature than one still dormant.
Does it start frost protection equipment automatically?
No. It only sends a WhatsApp warning with the blocks at risk and the expected coldest hour. Starting wind machines, irrigation, or other frost protection is still a decision your crew lead makes and acts on.
What if the forecast changes overnight?
It checks the forecast again if conditions shift significantly and sends a follow up WhatsApp message, so the crew lead isn't acting on a stale forecast.
