Climatic conditions - In the higher regions of the country exist mountainous climate with various subtypes; - In the other parts is changing from continental to variable continental; - In the river Vardar valley and in the lower parts of some tributaries exist Sub-Mediterranean climate.

Flood Forecasting Activities • Collection and processing of Hydrometeorological data • Analysing meteorological products; • Receiving Weather Forecast; • Analysing hydrological data; • Water Forecast; • Hydrological Information and Alarming.

Meteorological Data Needs of new automatic stations especially in the mountainous regions Collection and processing of

Hydrological Data Needs of new automatic stations especially in the mountainous regions Collection and processing of

Analysing meteorological products • Satellite Maps -EUMETSAT; • Internet Maps -Wetterzentrale; -Meteo Blue; • NMM Maps; -temperature; -air pressure; -precipitation; -wind direction; -cloud cover • Forecast Meteograms.

Receiving weather forecast and alarming

Hydrological Analysing • Hydrological Data;

Flood forecasting of the upper catchment of the r.Vardar Hydrological Station Info Hydrological Station Rain Gauge Station

Graph-analytical method forFlood Forecasting • Estimation of average precipitation for relevant catchments;

Graph-analytical method

Hydrological Information and Alarming • Centre for Crisis; • Centre for informing and alarming; • Relevant Ministries; • Public and Media

What is reality • With our NMM model, weather forecast is on very high level; • METEO ALARM give public information about bad weather situations; but • for better water forecast we need modernization of our hydrological network, raingauge system and update of our hydrological forecast model.
