Two reasons... a) the stretch of time without an El Nino and b) warm waters in the Pacific. If you take a look at a sea surface temperature map, and/or look back at maps from the past few seasons, you'll see that the subtropical Atlantic has been anomalously warm. When this occurs, the Hadley Cell (you can read a lot about this on the internet) is broadened and the air across the tropical Atlantic is forced to sink (which leads to drying). An El Nino is correlated with below-average ocean temperatures in this region, which is good for Atlantic tropical cyclone activity...but we haven't seen one to cool the waters. Additionally, the warm waters in the Pacific act to focus the upward MJO (rising air) there, which subsequently leaves the descending branch of the MJO (sinking air) over the Atlantic.
