Weather: Forest fuel flammability up this week despite recent rains

precipitation and lower than climatically expected temperatures which prevailed in Greece from Thursday 8 November to Sunday 14 August resulted in a significant reduction in the flammability of dead wood fuel.

In particular, based on measurements from the network of automatic weather stations of the National Observatory of Athens (EAA)/meteo.gr, the flammability of dead wood fuel on Sunday afternoon is estimated to be low for the season in most cases. countries.

However, based on the latest available forecast data analyzed by the pyrometeorological group FLAME EAA/meteo.gr, a significant increase in the flammability of dead wood fuel is expected. during the new week from 15 to 21 August.

The reason for this increase is a predicted gradual rise in temperature to values ​​well above climatically expected, combined with a predominance of dry conditions.

Under these conditions, dead wood fuels, especially thinner ones such as leaves, needles, small branches and logs, release moisture into the atmosphere and dry out quickly. This makes it easier to ignite when a heat source is present, and then supports combustion and quickly spreads the fire.

Based on the forecast for moisture content in dead wood fuel for Wednesday, August 17, it is expected to fall below 10% in just three days over most of the country.

These values ​​create a favorable background for the emergence and spread of forest fires.
