Abstract
This work presents a detailed scientific concept of an operational warning system concerning weather hazards, which is a component of the IT System for Country’s Protection against extreme hazards currently under development in Poland. The system displays eight weather hazards that prevail in Poland (air temperature extremes, heavy rainfall, strong wind, intensive snowfall, fog, glaze, rime, and thunderstorms with hail), which are presented on the maps. The information will also be made available to the public in the form of warnings sent automatically via the Internet or text messages. The weather hazard maps consist of two highly complementary components. The first contains maps of areas vulnerable to the hazards’ occurrence (climatological maps). These are based on observational and measurement data covering the period of 1951/1966–2010. The second component consists of operational maps based on current weather conditions, including primarily predictive data provided by the mesoscale numerical weather prediction model ALADIN (warning maps). The climatological information has been applied to the operational maps for several extremes not directly predicted by the ALADIN model.

Summary
Primarily weather-related natural disasters, play a prominent role in the functioning of the environment, society, and economy They cause economic losses as well as human suffering and casualties. Within the implementation of the WMO Disaster Risk Reduction Programme (WMO 2014), early-warning systems (EWS) (WMO 2005, 2010) are being developed in a growing number of countries. For the realization of the concept of the abovementioned Disaster Risk Reduction Programme, meteorological hazard maps were implemented as a part of the system Their main aim is to present select weather phenomena in Poland, by relying on a detailed climatological analysis and displaying the information on their forecast occurrences. The work discusses the scientific and climatological basis, methodological assumptions, and solutions that were employed in the presentation of particular meteorological hazards
