The website has cost €400,000, and work on it started more than two years ago. It was originally decided that it should be ready by the end of 2018, but the website has become available to the public only about a month ago.
The variety of mistakes is broad - wrong rainfall forecasts, location of weather stations on the map, sophisticated operational meteorological data.
LSM forecaster Toms Bricis, commenting on the website, said: "(..) for example, the website regularly shows what they indicate as the red warning: extreme rainfall which can cause flood, endanger human life, interrupt supply of electricity (..).
In fact, this is simply a mistake: one millimeter of rain displayed as fifty. A simple fiftyfold mistake."
The only excuse, Bricis said, is that the page is "in the initial stages", despite it having missed the intended deadline by two years.
Antra Zariņa said it was planned to correct the errors and loopholes on the website by the end of this year, but the portal will continue to develop next year by introducing new products. Zariņa could not specify what they will be because it depends on users' expectations.
