The poor weather conditions in Guatemala resulted in a moderate lahar on April 4 in the early evening on the slopes of Fuego.
The lahar, which borrows the Seca barranca, consists of blocks of pasty material of two meters in diameter, stones, branches and tree trunks, and generates steam columns, endorsed by the high temperature recorded.
It is not excluded that the rains cause lahars in other drainages during the night or the morning of April 5th.
