Experts predicted a wave of immigrants when Title 42 restrictions ended in May. However, crossings have reached new lows for various reasons, some of them temporary.

A Colombian official said that in recent weeks there have been fewer migrants crossing from Colombia into Panama through the dangerous Darien jungle. The rainy season has made the journey even muddier, slippery and treacherous.
