Tropics Trying To Awaken?


There are two areas of convection ongoing in the Tropics this morning, one in the Eastern Caribbean, and another Southeast of Florida over the Bahamas in the Atlantic. However, the odds are against these two areas of convection because of high pressure in the vicinity of #2, and too much wind shear in the upper levels over #1. In fact, too much shear in the atmosphere is a sign of the El Nino conditions in the Eastern Equatorial Pacific. During El Nino hurricane seasons, tropical cyclone development can be suppressed because storms are unable to organize in the shear tearing the circulation apart. So indications are that the Tropics are trying to get their hurricane season act together...but perhaps El Nino is going to prevent storms from organizing and strengthening.
