Announcing New Weather Visuals in v2.5.0
We are excited to announce the release of v2.5.0, taking the Weather Visuals even further, right down to your own region and summit - available now across the UK and Ireland:
- Weather Fronts map — a new synoptic chart showing cold, warm and occluded fronts with isobars and pressure centres, so you can see the bigger picture of what's driving your local forecast.
- New Region Weather Visuals card & page — a regional map showing 24hr Wind Flow, Precipitation, Temperature, Cloud Cover, Freezing Level, Midge Forecast & Weather Profile, for all 37 mountain regions across the UK, Isle of Man and Republic of Ireland.
- Region Weather Profile chart — a cross section elevation of the region showing key peaks, cloud levels, visibility, precipitation, wind and temperature over 24 hours, so you can see how conditions change with height across the whole area.
- New Mountain Location Weather Visuals card & page — a summit map showing 24hr Wind Flow, Precipitation, Temperature, Cloud Cover, Freezing Level & Weather Profile, for any of over 11,500 hills and mountains.
- Mountain Weather Profile chart — a West to East elevation profile of the mountain showing cloud level, visibility and a Terrain Wind Map with speed range, mean wind speed and gusts across the terrain, so you can see how wind changes as you climb.
- Midge Forecast — a seasonal 0–5 midge activity forecast overlay on the Region Weather Visuals page, so you know what you're walking into before you set off.
Release v2.4.0: New Synoptic Weather Visuals
Mountain Weather UK brings the forecast to life with interactive, real-time synoptic maps of the UK and Ireland — all beautifully presented, hour by hour, up to 72 hours ahead, with a time slider so you can scrub through the whole forecast at a glance:
- Wind — animated wind flow across the landscape, showing speed and direction hour by hour as conditions change through the day.
- Precipitation — rain, sleet, snow and thunder plotted by location, so you can see exactly what's moving through and when.
- Pressure — atmospheric pressure gradients and animated isobars, showing the bigger picture of what's driving the weather.
- Temperature — temperature patterns across the UK and Ireland at a glance.
- Clouds — cloud cover from valley fog to high cirrus, with new, more accurate cloud weather codes (Mainly Clear, Partly Cloudy, Mostly Cloudy, Mainly Overcast, Hill Cloud, Hazy, Cloud Inversion) for a clearer picture of what to expect overhead.
- Freezing Level — the altitude where temperature reaches 0°C, essential for judging where rain turns to snow.
- Sun and UV — sunshine duration and UV index, so you know when to reach for the sun cream as well as the waterproofs.
Introducing New Weather Animations in v2.2
The Mountain Weather UK App v2.2 has now been released! This version includes new beautiful Mountain Weather Animations on the forecast page.
The animations use the weather data to produce animations based on the weather type, cloud cover, wind speed and direction. These are translated into weather animations using a physics engine to create the clouds and precipitation.
These are entirely optional and you can turn them off if you don't like them and just show the static weather backgrounds. Or you will also be able to turn both off and just have a plain background.
