Two instances of line type angel echoes as observed on the scope of a high powered 3-cm radar at Dum Dum Airport, Calcutta, have been presented in this paper. These appeared in the vicinity of thunderstorm cloud cells and were detected prior to the occurrence of surface squalls. The possible sources of the angel echoes have been discussed. It has been suggested that the line type angel echoes were due to undercutting of the weather front.
