What it does, and what it doesn't
Rain Nearby means any rain
Light rain counts too. The alert is there so you take an umbrella, not only for storms.
See where it is raining
Tap the weather card for rain measured at NEA's gauges: how many stations islandwide are wet, and the heaviest reading near you or near any area you pick.
Measured, with the station named
Temperature, humidity and wind come from the nearest NEA station, named with its distance and time, next to NEA's 2-hour forecast.
MRT disruptions too
MRT alerts start on for the lines near your saved stops and stations, and you can switch any line on or off.
On Android and iPhone
Android
Alerts arrive in English, 中文, Bahasa Melayu or தமிழ், following the app.
