Data, not a government site
How NEA weather products work
This site republishes public products from the National Environment Agency and Meteorological Service Singapore. It is not NEA, and it is not weather.gov.sg. The homepage is the live dashboard. This page is the map of which product answers which question.

What this site is not
It is not an official warning service. It does not issue forecasts of its own. It does not sell ads on the weather. The about page covers who runs it. The guides cover how to read the products.
