Somerset-based flood aid volunteers have joined with the British-based Sikh charity that came to the aid of the Levels to help in the Balkans flood disaster.
Mark Rosales and Tim Holmes, from the Flooding on the Levels Action Group are due to arrive in Sarajevo today, with a further team hoping to arrive on Monday, depending on funding.
More than one quarter of Bosnia's 3.8 million population has been affected by the floods after the heaviest rainfall on record began last week. At least 47 people have died as the swollen river Sava burst its banks, submerging houses and churches.
Chris Davey, son-in-law of a Somerset beef farmer, is already in Serbia with a team from the county.
A FLAG spokesman said yesterday: "The terrible events that have unfolded during the devastating floods in the Balkan region have galvanised the members of the Flooding on the Levels Action Group back into emergency relief mode once again.
"The suffering of the people in Serbia and Bosnia feels all too familiar to the people that live on the Somerset Levels and we feel compelled to help in any way that we can.
"Many items that were donated to us during the crises of the winter floods are in storage so FLAG volunteers, along with the Somerset Flood Relief Centre and members of the community are packing these goods up to send care packages to the afflicted regions."
"There is also a collection point for goods at the Latterday Saints church in Taunton."
FLAG was set up during the floods of 2012 to campaign for better water management throughout the Somerset Levels and catchment. It works with various agencies.
