Current Hyperlocal Storm alerts

These are the Hyperlocal Storms alerts (beta) identified around the UK for today. Using real-time radar rainfall we are tracking the path of areas of high-intensity rainfall and predicting their movement over the next hour, at 5-minute increments, using a machine learning algorithm. As these Hyperlocal Storms pass over any village, town or city we generate an alert. For customers interested in particular cities then we can create the alerts for any postcode sector in the city.

This is part of our MAP Rain service. For more information then click here.

We have created our own Hyperlocal Rainfall predictions for the past 5 years. Click here for more information and you can download the Hyperlocal Rainfall app on both the Google Playstore and the Apple App Store.

Hyperlocal Storm – predicting high intensity storms at any location

Hyperlocal Storm

Hyperlocal Storm tracks high-intensity rainfall, in near real-time, and predicts the movement of the storm for the next hour at 5-minute intervals.

We then overlay this information with a map of all urban extents in the UK to identify ANY village/town that will be affected. For major urban areas, we are generating alerts at the postcode sector level.

This service will be of particular interest to Councils and Companies covering large rural areas or having large numbers of locations dotted around the country.

The image below shows an example of the urban extents and postcode sectors around the Leeds area.

Why is this different – what is the benefit?

At present, using our MAP Rain point or polygon alerts, we identify rain events happening over the next 30 hours using forecast data. But, we need to know the location of that point or polygon.

With Hyperlocal Storm, we can identify any area at risk, without having to set that area up beforehand. So, for large rural areas, like Lincolnshire, we can predict these storms for any urban area across the 20,000+ km2 council area.

Next steps?

We are finalising testing at the moment and trying to work out the best way to visualise this information and/or share it with partners. This is where we need some help. We are keen to understand how users might want to use this information and share it within their organisations or with residents.

MAP Rain – new forecast alert dashboard

Our new MAP Rain alert dashboard now makes it much easier to keep track of forecast rain alerts for Points and Polygons in your area of interest. The alert dashboard updates every 5 minutes, as new rainfall data arrives, and updates the colour of your Points and Polygons depending on the level of flood risk. The alert dashboard also displays an animation of the forecast rainfall across the UK

The new forecast alert dashboard provides a simple way to see the alert status of your Points and Polygons along with an annimation of the forecast rainfall for the next 36 hours. We have designed this as a simple way to monitor flooding risk 24/7.

Toggling between current (Query) view and new Alert view

We have added a new button which switches between the existing view of the dashboard and the new Alert view.

New Alert view

The purpose of this new Alert view is to provide customers with a simplified 24/7 view of the rainfall and associated alerts in their area of interest.

  1. Click on the “Show Alarms” button to see the forecast state of your Points and Polygons
  2. The Alert colour will change as the alert state changes. The Points and Polygons will default to show the green Clear alert
  3. The dashboard refreshes every 5 minute so both the dashboard and the emailed alerts will be synchronised
  4. You can add an animation of the forecast rainfall for the next 36 hours. The animation shows the forecast rainfall for each hour and continuously replays. You can customise the speed of the update, the opacity of the image and the forecast duration
  5. You can stop the animation and use the Show Rainfall button to select historic or forecast rainfall for a particular time using the time slider that will appear. Note: The Points and Polygon alerts will not display historic colour changes, they only show show forecast alerts
  6. The forecast rainfall is displayed for the whole of the UK so you can have a better understanding of the rain that will impact your area of interest.
    Can switch back to the original dashboard view using the “Switch View” button.
