There is important information on the web about the global state of weather that comes from national observation networks, radars and satellites. Likewise, forecasts for the entire planet are published on the web, prepared with sophisticated computer models.
The vast network of automatic weather stations operated by San Luis (58 stations) makes it possible to validate these forecasts and consequently select which websites offer the best forecasts for each of 39 locations. Thus, the best forecasts for the province available in the world are used.
With this methodology, the weather forecast for the day and the next two (72 hours) is issued. Additionally, when there is a risk of unfavorable events (fog, hail, etc.), alerts are issued as soon as they are detected.
The forecasts are published on the website (www.clima.edu.ar) with high receptivity (120,000 monthly entries). To this, are added the local news media that disseminate these forecasts and conduct interviews with the forecasters. Related information is disseminated on Facebook, Twitter and Instagram.
The prediction of the general weather and the issuance of alerts are made by 6 forecasters trained at the University of La Punta, who cover 365 days a year from 6 to 21 hours.

• San Luis province, Argentina

The climate of San Luis presents a great diversity due to its orography that includes the massif of La Punta, the Conlara valley and the Comechingones mountain range. It is also a transition zone between a relatively humid region in the East and another desert in the West. Despite this spatial variability, the National Meteorological Service has only 3 stations, which are insufficient to inform about the weather and to issue and validate forecasts for other locations. The execution of the project, focused on providing local forecasts, allowed to overcome this lack. Now the population of the province receives more accurate forecasts and is warned of extreme weather conditions. In the particular case of 36 locations, it has specific information for its place of life or activity. That is, the right to consult and have relevant information has been extended, which is part of the common vision of the Information Society. This was possible due to the development of the provincial infrastructure that ensures connectivity throughout the province and facilitates applications such as those of the Project, in accordance with the idea that the opportunities offered by ICTs are for the benefit of all. The lack of meteorological and climatic information by the national State was exacerbated by the change in the regional climate that made the need for more and better information felt. Important climatic trends were registered during the last decades, probably linked to global climate change. The new conditions include a higher frequency of storms and heavy rainfall affecting the population and its resources. Consequently, the Project has as one of its main focuses generating the corresponding alerts. This is in line with a WSIS value, that is, in the use and deployment of ICTs, efforts should be made to generate benefits in all areas of our daily lives, particularly in disaster prevention.
