Close to 600 forest, bush and grass fires have been recorded by the Rescue Board (Päästeamet) in Estonia so far this year.
The Rescue Board declared a fire hazard period on 6 April following a relatively warm and dry spell for the time of year, a phenomenon experience across northern Europe.
Precautions which should be taken include safety measures even when making a fire in a private garden, and only using specially designated zones when on public land.
A pall of bluish smoke which spread across much of south and central Estonia on Thursday afternoon is thought to have originated from bush fires somewhere either in the Russian Federation or in Belarus.
