Those images are the 200-850mb wind shear and relative humidity respectively.
For the shear image, any color from dark blue to red will rip apart any cyclone that is forming or has already formed. The bottom image, relative, relative humidity, any color from light sand to brown is not conducive for tropical cyclones.
You will notice a 1005mb low south of Puerto Rico and 1010mb low by the Cape Verde Islands. Those entities, most likely tropical depressions, will probably not develop much due to the hostile environment.
