A lot little migrants on the border. "The numbers are decreasing overnight"

Sealing the barrier at the border, falling the temperature in connection with the coming winter, or possibly any kind of gratitude to the Belarusian government for beginning 2 border crossings that have been closed for respective years? Regardless of which of these factors - or possibly each of them has overtaken a bit - the number of migrants attempting to cross the Polish-Belarusian border illegally falls. This is confirmed by both border guards and activists. But everyone wonders what happens next? Is it just a temporary decline, or is it a permanent change?
