Ts Isaac Still Weak

Good Afternoon, Tropical Storm Isaac continues to become more defined and is expanding in size. The hurricane hunters are currently investigating the system and could find the center relocating further south and west than the previous fix. This could have an impact on eventuall track. The models are in fairly good agreement through day 3 keeping Isaac just south of Puerto Rico, Hispaniola. Then the models diverge somewhat with the Euro model staying south of Cuba and the GFS crossing eastern Cuba toward southern Florida. I have little confidence in the five day track of Isaac, so interests from the GOM to Florida should closely monitor this situation!! Thanks, Jeremy
