Prague weather, overpowered.
Rain timing from several forecast models, ČHMÚ stations, warnings and radar — for Prague first. A web app plus a Chrome extension.
In development · screen design final


Several forecast models side by side. You see how many of them expect rain, when it starts and roughly how much.
Current readings from ČHMÚ stations around Prague — Kbely, Libuš, Ruzyně and more.
ČHMÚ warnings with level, time window and a short description.
One full-screen radar with layers. Play it, or scrub through time.
48 hours by the hour, 14 days by the day, plus air quality, UV and pollen.
The app’s own visual system, “Pražské ticho” (Prague quiet): calm, dark by default, light when you want it. Desktop and mobile share one design.

How many models expect rain, and how sure the forecast is for 48 hours and 10 days.

The weather at a glance from the browser toolbar, without opening the app.





Screens from the approved design manual (Czech UI). Values on the screens are samples.
Designed and built at TMM: product, design system, web app and extension — all inside TMM.
