It is not always the case, but there has been some research to indicate that the Atlantic Hurricane Season is enhanced during La Nina events. Last year's hurricane season confirmed the opposite, that during an El Nino year Atlantic hurricane activity is suppressed. We are already calling for an above-average hurricane season as a result of warmer-than-average sea surface temperatures in the Atlantic, and with the additional support of low wind shear from La Nina we should be on track for an active season.
Right now, tropical activity is low in the Gulf, Caribbean, and Atlantic Basin, but we will be monitoring for any developments!
