D)region of greatest pressure decrease

The movement of a surface low-pressure area can be predicted by looking at the region of greatest pressure decrease. Low pressure systems move towards areas of higher pressure, so identifying the location of the lowest pressure can give an indication of the direction of movement. The orientation of isobars behind a cold front and in front of a warm front can provide information on the organization of the storm, but this information may not be directly related to the movement of the low-pressure area. Movement during the previous two hours is also not a reliable predictor of future movement, as weather patterns can shift quickly.
