The forecast on your call sheet was right when you sent it.
This is what tells you when it stops being right.
Once the call sheet goes out, the unit plans against the weather printed on it and nobody checks again. G-Casper Pro does. It pulls a fresh forecast for base camp every 30 minutes and compares it hour by hour against the sheet. A real change reaches the team by push notification. A severe one also goes out by SMS to the production office.
Weather alerts and radar come with every plan. Severe-weather texts use SMS credits, one per recipient.
What Counts as a Change
Each fresh hour is set against the same hour on the sheet. Rain up 20 points and past 30% is a change. So is wind up 10 mph and past 15, or a 15 degree swing in temperature. The floors keep a forecast going from 0 to 20% from paging anyone about a dry day. Severe is its own tier: wind at 35 mph or more, rain at 80% or more, or wording that turns to thunderstorms, hail, tornado, hurricane, tropical storm, blizzard, freezing rain or a dust storm. Every threshold can be changed per show. Drag the sliders and watch the finding change tier.
When the Watch Runs
The watch on a shoot day opens the moment the call sheet first goes out by email or text, or 12 hours before crew call if that comes first. It closes 12 hours after wrap. A sheet with no wrap time is treated as a 12-hour day, and a wrap earlier than call counts as the next morning, which covers night shoots. A day with no crew call is never watched: a day nobody has called is a day nobody is standing outside on. Until the sheet is sent, the baseline follows each new weather fetch. Once it goes out, the baseline freezes on what the crew was sent.

Who Hears About It
Push goes to everyone on the show who has switched notifications on for their device, and a worse forecast replaces the day's earlier notification instead of stacking up behind it. The severe text goes to the Production and Production Office departments by default, with the director left off. You can name other departments, or add and remove people one at a time. Each text carries a short link to the alert. The same finding is not sent twice unless it gets worse by a clear step, so a storm that holds steady all afternoon texts once. There are no quiet hours: a severe alert at 3 AM goes out at 3 AM.

Live Radar
Every day card in the Weather tab has a Live Radar view next to Hourly, centred on that day's base camp. It runs from an hour back to four hours ahead in 15 frames: observed radar every 10 minutes up to now, then forecast frames every half hour. Rain for each 15 minutes sits above the map and wind below it, with cells tinted where the wind crosses the limits for flying a 20x20, a 12x12 and a 6x6 overhead. Gusts get their own number, because the gust is what takes a frame down. Radar is drawn by Xweather and loads only when you open the view.
