Add your home, vineyard, or any spot you care about. Used by farmers, vineyard owners, event planners, and property owners.
Not a forecast. Not a weather app.
We track what's moving right now — and alert you before it arrives.
What is this app?
It notifies you when heavy rain is moving toward a place you care about. Add a location on the map and we'll let you know when heavy rain is approaching.
What is it useful for? Is this a weather forecast app?
It helps you plan ahead and avoid getting caught by incoming heavy rain — for your home, land, vineyard, or any property. This is not a forecast. We don't predict days ahead — we track what's happening now and notify you when rain is on the way.
How will I be notified?
By email, or by SMS if you add your phone number. You choose — and you can change it anytime from your dashboard.
How do I choose a location?
Search for a city or address and select it from the results — the pin moves to that spot. You can also drag the pin to fine-tune the exact position. The location name is set automatically based on the city.
How accurate is it? How often will I get notifications?
We aim to notify you before heavy rain reaches your location, but timing can vary. It's a simple tool meant to be useful, not exact. Notifications are sent only when there is heavy rain near your location — some weeks none, other times a few in a day.
What's the difference between plans?
Starter (free) lets you try it with one location and 3 notifications — enough to see how it works. Basic (€2.90/month) monitors one place with no notification limits. Plus (€7.90/month) covers up to 3 locations with more frequent updates — useful if you care about more than one place, like your home and land in a different area. Cancel anytime.
Where is this available? Is this a finished product?
Currently focused on Slovenia and nearby regions, using radar data from ARSO. More countries may be added over time. This started as a personal tool and is still evolving based on real usage and feedback.
What the service does
RainFlow monitors weather radar data and sends notifications when heavy rain is detected moving toward locations you have set up. It is a best-effort notification tool, not a guaranteed early-warning system. We do not predict weather days in advance — we track what is happening in real time.
No guarantee of alerts
Notifications depend on radar data availability, internet connectivity, and the accuracy of storm-movement predictions. Alerts may be delayed, missed, or occasionally incorrect. We are not liable for any damage, loss, or harm resulting from a missed or late notification. Do not rely solely on RainFlow for safety-critical decisions.
