Danger level 3 with extreme temperatures, which have significant effects on health, is predicted by the METEO unit of the National Observatory of Athens today for Athens and on Friday for Athens, Thessaloniki and Larissa.

Also, today in Thessaloniki and Larissa danger level 2 with extremely high temperatures is expected, and in Patras danger level 1 with very high temperatures.

On Friday, risk level 2 with extremely high temperatures will be in Patra and very high temperatures (level 1) in Ioannina.

In addition, a significant increase in the flammability of dead forest fuels is expected in our country in the coming days due to the gradual prevalence of very hot and dry conditions. Under these fire-meteorological conditions (hot and dry weather), dead forest fuels shed moisture, dry out and ultimately facilitate fire initiation and spread.

The METEO unit of the National Observatory of Athens, in collaboration with the scientific committee of the Arsht-Rock Resilience Center of the Atlantic Council, operationally applies the categorization of days with high temperatures for six major cities of the country (Athens, Thessaloniki, Larissa, Ioannina, Patras and Heraklion).

The categorization system is based on an algorithm for predicting the impact of upcoming days with high temperatures on the health of residents of the six cities. The algorithm takes into account, in addition to temperature, other parameters that affect human thermal sensation, such as humidity and wind. The categorization includes four classification categories (0-1-2-3), where 0 is high temperatures with risks for vulnerable people and 3 is the category with extreme temperatures and a significant health risk.
