This made it diffficult to forecast the storm , since it tracked through an area of 84 Â F ( 29 Â C ) water temperatures , light shear , and a large low-level cyclonic envelop with abundant convection .
This led to difficulties in forecasting , as its environment favored further strengthening ; the storm tracked through an area of 84 Â F ( 29 Â C ) water temperatures and light shear , and the system maintained a large low-level cyclonic envelop with abundant convection .
