An indirect low-pressure system is a type of atmospheric low-pressure condition where the center of low pressure does not lie directly over a region, but its effects are felt due to nearby pressure systems. In this situation, weather changes such as cloud formation, increased humidity, and light to moderate rainfall occur because air flows toward the low-pressure area from surrounding regions. The influence is often indirect, as the associated winds, moisture transport, or frontal systems extend into the area without the low-pressure center being overhead. Indirect low-pressure systems commonly cause unsettled weather and can act as a precursor to more intense weather conditions if the low pressure strengthens or moves closer.
