The MSLP animation is for the North Atlantic Ocean from 15 January at 0000 UTC to 17 January at 0000 UTC. It shows that lows are moving zonally north of 60°N, and that the value of the center remains above 960 hPa from 15 to 17 January. These lows are not associated with strong winds and will not generate high waves. So there’s no intense deepening, and the pressure values in the center of the lows are relatively high when compared to the situation in the first case.
The fetch oriented from north-northwest to south-southeast is also relatively short compared to the first case because the storm is closer to the coast.
