El Niño and La Niña events, indicated by anomalous warm and cold sea surface temperature in the Pacific Ocean, have significant effects on the ABC islands. La Niña events have positive rainfall anomalies and El Niño the opposite. La Niña's have been linked to an increase in TUTT lows and the K-index, while El Niño was the opposite. Above normal K-index during La Niña events suggests an increase in low-level moisture on the ABC islands. The surface to 500 mb dewpoints averages indicate above normal conditions during El Niño, while cap strength was below normal. The above normal surface to 500 mb dewpoint averages were linked to mid level moisture but had no effect on the rainfall anomalies. The unexplained Cap strength anomalies could be blamed on the time of the sounding.
