The frontal depression responsible for remarkable rainfall totals and record floods in Northern Ireland on the 21-22 October, 1987, was part of a synoptic sequence of severe storms that affected the British Isles in the middle of that month. The airflow relative to the synoptic system in which the precipitation event occurred, is examined within the framework of surfaces of constant wet-bulb potential temperature (Ow). Autographic rain gauge records are used to determine meso-scale precipitation areas throughout the passage of the depression. From these data, orographic enhancement of background moderate to heavy rainfall is found to be largely responsible for amounts in excess of 100 mm. This enhancement is associated with a deep, very moist, strong low-level airflow, and the release of potential instability in a slow-moving synoptic situation. This study elucidates the interaction of dynamic and orographic influences responsible for the meso-scale precipitation signatures associated with the synoptic event
